Holy crap it worked! Thank you thank you thank you. I tried the simple bleed just from the top at first and couldn't extract any air bubbles. Tried this way and it worked beautifully. I feel like an expert now.
nice video thanks for the walk though. one suggestion 3:45 do not put the brakes back on, if oil leaks it will get all over the brake disk. better to leave them hanging and put a bag or something underneat to catch any drips.
Good instructional video on this man..... I'll be doing both my zoom and nutts brakes in the coming weeks. One tip id give is when you remove the cup off the brake lever and before you at the srew back in the final time, adjust the brake lever tension screw till you see oil come up to the top of the oil screw hole, then put the screw back in (a little messy, but makes sure no air gets in the system)
Hi Lantea, Many thanks from France. After all the videos I watched before taking the plunge, yours is the best! I've just done the brake bleeding on my Dualtron Victor with you by my side for the step-by-step.💪🏽💪🏽
Hello there!. It’s a very nice video on how to bleed the zoom breaks. But i have some questions because im planning to bleed my scooter: 1. Ill be using a red shimano and you’re using a transparent one. How would i know if i flushed out the old oil? 2. What do you do with the leftover oil you used after you bleed your breaks? Do you discard them or you put it back on the new oil container ? I hope you can help me with this.. it’s my first time in doing it and i don’t want to screw my breaks. 🙏🙏🙏
I also used red shimano during my second brake bleed, it works fine. To flush out the old oil unscrew the bottom plug and to release the oil unscrew the top plug and let it drain out. It does not have to be 100%. Collect the old oil in a separate container and throw it out. Dont reuse the old oil.
When I received my Varla Eagle One I had no brakes! The levers pulled all the way to the handlebars. I was pissed to say the least. I had Sram and Shimano bleed kits for my mountain bikes but their fittings didn't fit the master cylinder port of the Zooms. I was desperate to try my new ride out so I took out the bleed screws at the master cylinders and just kept the hole filled with the Shimano mineral oil enough to not allow air down in the plunger and flicked the levers enough to burp but not puke out fluid. After only a dozen or so flicks per side I had full lever on both brakes. I couldn't believe how easy it was! And I was off! - to see how many times I could almost kill myself on a scooter with shitty handling that does 40mph! At least the breaks work great!
Which tool are you referring to? I just use standard pliers, and a screwdriver with allen and torx bits that are listed in the description. Don't have a specific link for the ones shown as I had them for a long time, if you have trouble finding similar ones on amazon or other gardware store let me know and I will try to link some similar ones.
Could you possibly tell me what the exact model of hydraulic brakes is on the Apollo? I'm looking for aftermarket hydraulic brakes & it's one of the most complex items I've ever tried to find. I've got a '22 Apollo with regular brakes (very big mistake not getting the one with hydraulic brakes) & so far, "Zoom" is all I can get out of anyone. I know it's 140mm discs, top-mount calipers, both on the right side of the wheels. It's impossible trying to find out what people who speak Chinese mean by "right side" - sometimes it's handlebars, sometimes it's calipers.
The ZOOM brake model number should be HB-875-E. Here are all the details I could find when I was trying to repair my ZOOM brakes imgur.com/a/07yk16h But I would strongly advise you to get the NUTT hydraulic brakes instead of the ZOOM brakes. The ZOOM brakes on my Ghost (VDM-10) started leaking at the caliper and there was no way to repair them. I decided to upgrade to NUTT hydraulic brakes and so far they are way better. I bought a set on aliexpress for around $110 (US). The seller I bough from no longer sells them, but if you search for "NUTT Hydraulic Disc Brake Set" you will find plenty of sellers, then just find a listing that clearly indicates the correct brake caliper orientation (on the Ghost both are on the right side), you can always also confirm with the seller over chat before you order (just an example aliexpress . com/item/1005005202156542.html no idea if this seller is good, you need to do some research on it and compare with other sellers). Hope this helps.
@@Lantea13 Thank you, you have no idea how long I've been searching for a simple model #. It's a huge mess of configs (right handlebar for rear brake, which is on right side, 140mm disc, etc, etc), and so far you're the first person to ever direct to me to a specific model #. I knew what to get, but the configs were all in broken English (e.g., "Right side" means handlebars to one person, but means disc/caliper to another - specifics always seem to be missing). I appreciate your going the extra mile here.
Hello thank you for that amazing video. I have question ; I realize that especially in hot days my breakpad squize the disk and give more heat to electrical motor. Do I have any change to little bit loosen the brake pad from disk?
On hydraulic brakes there is no way to loosen the brake pad squeeze on the brake disc, that is adjusted automatically as the brake pads wear down; you only need to center them on the brake disc properly. The heat from the brake disc should have no impact on the temperature of your motor.
@@Lantea13 Thank you for your answer, I realized that in summer hot days may hydraulic oil expand and squize brake pad. I feel that motor wants to go further but brake do not let it easily at that time .In evening I didnt face such problem.

Hi. I am about to but the bleed kit that you put the link. But is there two same port adapter thread in that kit? It seems like you need one for the caliper and one for the lever. Pls let me know. THnx
Everything I used was from a single EZmtb bleed kit. It had all the parts in it for both the top cup attachment as well as the bottom syringe attachment, so if you buy one it should have parts to do the bleed as I did it in the video.
Nice video I'm currently fixing my varla eage one icause a a bent disc brake I removed the zoom caliber and 4 sliver washers came off from the bottom. I'm fixing the front one not the back tire I'm a little confuse? Help
As long as its miniral oil for bicycle hydraulic brakes it should be fine. If you are switching to a different brand oil its generally recomended to empty the old oil and fill with the new one. If a little bit stays in it should be fine.
@@Lantea13 thank you for coming back to me. Do you by any chance know what the size of the tiny washer is? The prev bike shop that bleeded it for me. Never puted the one washer back. When i did the bleeding myself over the weekend i saw that one the one side the tiny wahser is gone. And i did tell them to be aware of it. But they have no pride in their work it seems.
@@sn3ke124 Which washer? Do you mean one under this screw ruclips.net/video/d4OY8q4Ymks/видео.html older zoom models had a washer here, but there was no washer under this screw in my brakes. If you mean a different one let me know which and I might be able to help.
@@Lantea13 yes exactly under the screw as in the video. I also have zoom breakes. But mine has a tiny washer under the screw like u said the old ones use to have.
@@sn3ke124 Sorry not sure what size it is, since I can't measure mine. If you still have the other washer you could take it out and go to a bicycle service or hardware store and ask if they have a same one. If not take the screw instead and measure the diameter of the opening.
They were stock on the scooter. But I found them here revrides.com/collections/all-accessories/products/zoom-hydraulic-brake-kits You can probably get them cheaper on sites like aliexpress. You should also consider NUTT brakes if you are upgrading, as those are generally regarded as better than Zoom brakes.
Yes, the links to the bleed kit I used are in the video description. e.g. see: Bleed kit - EZmtb Bleed Kit ezmtb.com/ www.amazon.de/dp/B07K9J32XD/ www.amazon.de/dp/B08D922KYF/ www.amazon.com/dp/B089MFMTD5/
Not sure what might be causing the smoke. Maybe if some oil residue was left on the brake disc or brake pads it might be smoking when the brakes heat up during use.
@@Lantea13 i had very much trouble to put in brake pads it took my maybe 3 hours i really pressed out the brake so it could fit . Its still coming smoke i think its to tight how can I lossen the place so its not so tight normally its not like that it happend after i was bleeding the brake
@@fixmyscooter729 Did you place a block between the brake pistons before you started the bleeding? (ruclips.net/video/d4OY8q4Ymks/видео.html) If not, that is the only reason I can think of why the brake pads would be hard to put back and too tight. If you did not use the brake block to keep the spacing for the brake pads, the only way to loosen it is to bleed out some oil and allow the pistons to fully retract and insert the brake block to maintain the correct spacing.
Afaik, it means that you have some air trapped in the brake lines. If you bleed the brakes and get the air bubbles out it should solve the spongy brake problem.
Not sure if its normal, but it is common on stock tyres that are not manufactured perfectly and are not balanced. You can try to balance the wheel with weights (ruclips.net/video/zSzrtAGhc60/видео.html), or if you get a high quality tyre such as PMT it should not wobble if seated correctly. Cheap chinese tyres will wobble as they are not perfectly balanced.
I can't understand why was so difficult ask question ti the direct seller... Anyway , they tell me to use " mineral oil,DOT 4 " So why here i see mineral oil but whith 3 " not DOT " write on the box??? all zoob brake was the same ? That looks like my ( gunai 5600W )
I had the same problem, no seller can even tell me who manufacturers the zoom brakes, or provide a manual to them. The ZOOM brakes use mineral oil, Not DOT fluid, do not use any DOT fluid or you can damage the seals. There is no manual to the zoom brakes and no bike or scooter shop sells zoom oil (at least where I am), so your best option is to just buy any brand mineral oil that can be used in bicycle brakes. The original oil in my zoom brakes had red colour so the closest to it is the Shimano mineral oil, I got a different one because that was the only one they had at my local bike shop at the time.
Not sure If you're still responding to comments but can I use any bleed kit for these brakes or do I need the specific one you're using? Thanks in advance
Hi, always responding :) You can use other bleed kits, but you need to make sure the bleed kit you use has the correct size adaptors to use with the brakes. Usually the bleed kit has a list of compatible brakes its designed for.
Hi, the scooter came with the zoom hydraulic brakes already installed. If you have the version with mechanical breaks its possible to upgrade to hydraulic brakes. You can check out this post www.reddit.com/r/ElectricScooters/comments/rq0nn2/ghost_mechanical_to_full_hydraulic_nutt_brake/ where a user upgraded to NUTT brakes.
I bought the bleed kit in a local scooter shop, but I linked the US and German amazon store pages in the video description where you can buy the same kit, check the video description above for all the used tools. The EZmtb bleed kit had the needed adapters for the zoom brakes. Let me know if you are still having trouble finding it. here is another link I found www.amazon.de/-/en/Bicycle-Mountain-Hyaraulic-Bleeding-Mineral/dp/B08D922KYF/ or for CA e.g. www.amazon.ca/Professional-Universal-Hydraulic-Bicycle-Mineral/dp/B07FYFDNSY/ you will find more if you search for EZmtb bleed kit. This one should work as well as it specifically mentions zoom brakes, but I have not tested it, so no guarantees www.amazon.de/Cycobyco-Mineral-Hydraulic-Shimano-HS33-Nutt/dp/B07845XW4X/
I don't think so. You can adjust the spacing of the brake lever with the tiny screw (imgur.com/a/pLNUNSU) but that won't really improve the braking. You can also try a top bleed. You take out the reservoir screw on the brake lever, put in the yellow funnel (with a bit of hose and a hose clamp), put some oil into it and press the brake lever several times until all air bubbles come out, then secure the hose clamp and remove the funnel with the remaining oil, and screw back the reservoir screw. A top bleed can help a bit, if you don't want to do the full bleed; but if your brakes are very bad you really should do a full bleed as in the video, as the top bleed is of limited help if you have a ton of air in the brake lines. If you have any questions about the full process in the video, feel free to ask, and I will try to help where I can. If you really don't feel like doing it yourself, any competent bike shop service should be able to bleed the brakes for you, as they are basically the same as on bicycles.
In that case I am not sure what size o-rings it uses, I only had to deal with both my calipers leaking, but in the end I was not able to fix them even with new orings and just replaced the whole zoom brakes with nutt hydraulic brakes. Maybe someone else has experience with the brake levers, if not, you might just have to try and disassemble them and see what orings or other parts are faulty. The main problem with zoom brakes is that there is no service manual or any other manual or documentation available from anyone about the brakes; and the only advice I got from the seller was to replace the whole brakes when they leak...
@@Lantea13 its actualy not orings , its a different type of seal , kooks like in shimano leawers , I was ither thinking to order shimano seals and mayby ill get Lucky with the size , or just replace it with normal orring , in theory it should work ,its only low pressure side seal , and other leavers using just normal orings
I've a Buyoeda scooter with same zoom brakes, and my front brake started squirting fluid where the brake pads are, I don't know what to do or what caused it. Has anyone encountered this?
I have not encountered this issue, but it could be due to the rubber o-ring in the piston being damaged. If the leak is big you could try taking apart the caliper to see what is broken inside and ask a local bike repair shop if they have a spare part that would work. The problem with zoom brakes is that there are no spare parts, manuals, or guides available anywhere for them, so you will most likely need to replace the whole caliper if there is a leak.
@@Lantea13 Thanks so much for the quick reply. I guess i'll have to order new ones. I just don't know what model those are,they're exactly like the ones in your video. All i see on amazon is HB-875. Or i might have to order from China. Today's a terrible day for me, because I use the scooter for work :(. But thank you so much for the information. Hopefully i'll get it fixed soon.
@@lukasgadzijevas7163 From my research they should be the HB-875-E this is what I was able to find out about them imgur.com/a/jFBpwiN I also got a leak in my zoom brakes, but at the banjo where it connects to the caliper. Luckily its a slow leak so I still did not get around to fixing it. I ordered replacement NUTT brakes instead of zoom, as I heard they are more reliable and you can find bit more info about them online. I ordered them direct from china as it was about €60 cheaper compared to a local shop. But you need to make sure they are compatible with your scooter setup. From what I remember there were some sellers in EU that sell a replacement zoom brake caliper for around €50 iirc. The full NUTT set cost about €115 from allie seller.
@@lukasgadzijevas7163 Found the site in my favorites with the zoom brake caliper fastride.fr/en/pieces-pour-dualtron/1764-etrier-avant-de-frein-zoom.html and fastride.fr/en/pieces-pour-dualtron/1781-etrier-arriere-de-frein-zoom.html might be the cheaper option if you want to stick with zoom brakes.
Yes, that should work fine. I used it myself when I needed to bleed the brakes again. In theory any mineral oil for bicycle brakes should work. If you are switching between different oil brands its best to drain all the old oil out first, before filling the system with the new mineral oil. The original oil in my Zoom Brakes had red colour similar to the Shimano mineral oil.
The red Shimano mineral-oil is (according to label) compatibel with all mineral oils, and will work on any system that uses mineral oil. I would however do as Lantea here writes and first drain old oil if you are changing brand and/or if the old oil has not been changed for several years. Another suggestion is to use the mineral oil that is easiest available to you.
I did it after 450km, but it was not good out of the box. I only did a top bleed back then, and it was usable. But as I had more downtime over winter I wanted to do it properly to get ready for Spring riding.
I am not sure. These were the stock brakes on the VDM-10 scooter. There is no model number on them that I could see. They are the same I have seen on many other electric scooters, such as Vsett, Dualtron, Zero, etc. I tried to get a manual for the brakes, but the manufacturer of the scooter as well as several sellers I asked all said there is no manual or more detailed information on the Zoom Brakes.
Fail 15:53, Should never reuse a lower grade Chinese knockoff brake caliper cotter pin, and Always replace said pin with premium grade cotter pins. Said reused pin will eventually fail & loosing or back out when your failing to brake while failing to beat a train at a train crossing and that will be the end of you in a instant, cheap life with a cheaper unsafe result.
Well, it held up for 12+ months and through several more brake bleeds, until I replaced the whole brakes with NUTT ones because of the constant oil leaks on the zoom brakes.

You can probably get them cheaper on sites like aliexpress. You should also consider NUTT brakes if you are upgrading, as those are generally regarded as better than Zoom brakes.
@@Lantea13 Best video I saw online actually expalinning this procedure. Thank you
@@Nuno_Tomas Your welcome, glad it helped you out :)
Do you have a link for the bleed kit . I bought one and It doesn’t have the fittings for the caliper nor for the master cylinder on the brake handle .
Yes, the links to the bleed kit I used are in the video description.

I was bleeding and put new oil IN my dualtron but when brake it Comes smoke fro the brake . What is this i noticed it direktly
Not sure what might be causing the smoke. Maybe if some oil residue was left on the brake disc or brake pads it might be smoking when the brakes heat up during use.
@@Lantea13 i had very much trouble to put in brake pads it took my maybe 3 hours i really pressed out the brake so it could fit . Its still coming smoke i think its to tight how can I lossen the place so its not so tight normally its not like that it happend after i was bleeding the brake
@@fixmyscooter729 Did you place a block between the brake pistons before you started the bleeding? (ruclips.net/video/d4OY8q4Ymks/видео.html) If not, that is the only reason I can think of why the brake pads would be hard to put back and too tight.
If you did not use the brake block to keep the spacing for the brake pads, the only way to loosen it is to bleed out some oil and allow the pistons to fully retract and insert the brake block to maintain the correct spacing.
What does it mean if the brake lever feels spongy after folding and unfolding it and then the pressure comes back after priming the lever?
Afaik, it means that you have some air trapped in the brake lines. If you bleed the brakes and get the air bubbles out it should solve the spongy brake problem.
At the end of the vidrio, when testing no rubbing in the pads on the rotor, your tire seemes to wobble. Is this normal?
Not sure if its normal, but it is common on stock tyres that are not manufactured perfectly and are not balanced. You can try to balance the wheel with weights (ruclips.net/video/zSzrtAGhc60/видео.html), or if you get a high quality tyre such as PMT it should not wobble if seated correctly. Cheap chinese tyres will wobble as they are not perfectly balanced.
I can't understand why was so difficult ask question ti the direct seller...
Anyway , they tell me to use " mineral oil,DOT 4 "
So why here i see mineral oil but whith 3 " not DOT " write on the box???
all zoob brake was the same ? That looks like my ( gunai 5600W )
I had the same problem, no seller can even tell me who manufacturers the zoom brakes, or provide a manual to them.
The ZOOM brakes use mineral oil, Not DOT fluid, do not use any DOT fluid or you can damage the seals.
There is no manual to the zoom brakes and no bike or scooter shop sells zoom oil (at least where I am), so your best option is to just buy any brand mineral oil that can be used in bicycle brakes. The original oil in my zoom brakes had red colour so the closest to it is the Shimano mineral oil, I got a different one because that was the only one they had at my local bike shop at the time.
@@Lantea13 how STUPID can be this china seller!!??! They tell me mineral dot,like if was the same thing not the opposite
Very helpful! Thanks very much!
Not sure If you're still responding to comments but can I use any bleed kit for these brakes or do I need the specific one you're using? Thanks in advance
Hi, always responding :) You can use other bleed kits, but you need to make sure the bleed kit you use has the correct size adaptors to use with the brakes. Usually the bleed kit has a list of compatible brakes its designed for.
Hi bro can i ask how you installed your hydraulic brakes 😊
Hi, the scooter came with the zoom hydraulic brakes already installed. If you have the version with mechanical breaks its possible to upgrade to hydraulic brakes. You can check out this post www.reddit.com/r/ElectricScooters/comments/rq0nn2/ghost_mechanical_to_full_hydraulic_nutt_brake/ where a user upgraded to NUTT brakes.
Where did you buy the tools for bleeding the caliper?
the say shimano bleedinh kit wont fit.
Thanks.
I bought the bleed kit in a local scooter shop, but I linked the US and German amazon store pages in the video description where you can buy the same kit, check the video description above for all the used tools. The EZmtb bleed kit had the needed adapters for the zoom brakes.
Let me know if you are still having trouble finding it.
here is another link I found www.amazon.de/-/en/Bicycle-Mountain-Hyaraulic-Bleeding-Mineral/dp/B08D922KYF/ or for CA e.g. www.amazon.ca/Professional-Universal-Hydraulic-Bicycle-Mineral/dp/B07FYFDNSY/ you will find more if you search for EZmtb bleed kit.
This one should work as well as it specifically mentions zoom brakes, but I have not tested it, so no guarantees www.amazon.de/Cycobyco-Mineral-Hydraulic-Shimano-HS33-Nutt/dp/B07845XW4X/
Is there a way to adjust the brakes without bleeding them? I just received my scooter and my back brakes don’t have much stopping power at all
I don't think so. You can adjust the spacing of the brake lever with the tiny screw (imgur.com/a/pLNUNSU) but that won't really improve the braking.
You can also try a top bleed. You take out the reservoir screw on the brake lever, put in the yellow funnel (with a bit of hose and a hose clamp), put some oil into it and press the brake lever several times until all air bubbles come out, then secure the hose clamp and remove the funnel with the remaining oil, and screw back the reservoir screw.
A top bleed can help a bit, if you don't want to do the full bleed; but if your brakes are very bad you really should do a full bleed as in the video, as the top bleed is of limited help if you have a ton of air in the brake lines.
If you have any questions about the full process in the video, feel free to ask, and I will try to help where I can.
If you really don't feel like doing it yourself, any competent bike shop service should be able to bleed the brakes for you, as they are basically the same as on bicycles.
Thank you for this video!!
Hello , my zoom brake is leaking from pump , did anyone had this problem and know the o-ring size to fix it ? 😀
By pump, do you mean the brake lever on the handlbars or the brake caliper on the brake disc?
@@Lantea13 brake lever
In that case I am not sure what size o-rings it uses, I only had to deal with both my calipers leaking, but in the end I was not able to fix them even with new orings and just replaced the whole zoom brakes with nutt hydraulic brakes. Maybe someone else has experience with the brake levers, if not, you might just have to try and disassemble them and see what orings or other parts are faulty. The main problem with zoom brakes is that there is no service manual or any other manual or documentation available from anyone about the brakes; and the only advice I got from the seller was to replace the whole brakes when they leak...
@@Lantea13 its actualy not orings , its a different type of seal , kooks like in shimano leawers , I was ither thinking to order shimano seals and mayby ill get Lucky with the size , or just replace it with normal orring , in theory it should work ,its only low pressure side seal , and other leavers using just normal orings
I've a Buyoeda scooter with same zoom brakes, and my front brake started squirting fluid where the brake pads are, I don't know what to do or what caused it. Has anyone encountered this?
I have not encountered this issue, but it could be due to the rubber o-ring in the piston being damaged. If the leak is big you could try taking apart the caliper to see what is broken inside and ask a local bike repair shop if they have a spare part that would work.
The problem with zoom brakes is that there are no spare parts, manuals, or guides available anywhere for them, so you will most likely need to replace the whole caliper if there is a leak.
@@Lantea13 Thanks so much for the quick reply. I guess i'll have to order new ones. I just don't know what model those are,they're exactly like the ones in your video. All i see on amazon is HB-875. Or i might have to order from China. Today's a terrible day for me, because I use the scooter for work :(. But thank you so much for the information. Hopefully i'll get it fixed soon.
@@lukasgadzijevas7163 From my research they should be the HB-875-E this is what I was able to find out about them imgur.com/a/jFBpwiN
I also got a leak in my zoom brakes, but at the banjo where it connects to the caliper. Luckily its a slow leak so I still did not get around to fixing it. I ordered replacement NUTT brakes instead of zoom, as I heard they are more reliable and you can find bit more info about them online. I ordered them direct from china as it was about €60 cheaper compared to a local shop. But you need to make sure they are compatible with your scooter setup. From what I remember there were some sellers in EU that sell a replacement zoom brake caliper for around €50 iirc. The full NUTT set cost about €115 from allie seller.
@@lukasgadzijevas7163 Found the site in my favorites with the zoom brake caliper fastride.fr/en/pieces-pour-dualtron/1764-etrier-avant-de-frein-zoom.html and fastride.fr/en/pieces-pour-dualtron/1781-etrier-arriere-de-frein-zoom.html might be the cheaper option if you want to stick with zoom brakes.
Is the red Shimano mineral oil also suitable?
Yes, that should work fine. I used it myself when I needed to bleed the brakes again. In theory any mineral oil for bicycle brakes should work. If you are switching between different oil brands its best to drain all the old oil out first, before filling the system with the new mineral oil.
The original oil in my Zoom Brakes had red colour similar to the Shimano mineral oil.
The red Shimano mineral-oil is (according to label) compatibel with all mineral oils, and will work on any system that uses mineral oil. I would however do as Lantea here writes and first drain old oil if you are changing brand and/or if the old oil has not been changed for several years.
Another suggestion is to use the mineral oil that is easiest available to you.
Nice instructions. How many miles/km did you have on your ghost before having to do this maintenance?
I did it after 450km, but it was not good out of the box. I only did a top bleed back then, and it was usable. But as I had more downtime over winter I wanted to do it properly to get ready for Spring riding.
what zoom model is that?
I am not sure. These were the stock brakes on the VDM-10 scooter. There is no model number on them that I could see. They are the same I have seen on many other electric scooters, such as Vsett, Dualtron, Zero, etc.
I tried to get a manual for the brakes, but the manufacturer of the scooter as well as several sellers I asked all said there is no manual or more detailed information on the Zoom Brakes.
I did bit more research; it looks like the model number of the brakes is ZOOM HB875-E. That is all I could find, still no manual/parts list, etc.
Fail 15:53, Should never reuse a lower grade Chinese knockoff brake caliper cotter pin, and Always replace said pin with premium grade cotter pins. Said reused pin will eventually fail & loosing or back out when your failing to brake while failing to beat a train at a train crossing and that will be the end of you in a instant, cheap life with a cheaper unsafe result.
Well, it held up for 12+ months and through several more brake bleeds, until I replaced the whole brakes with NUTT ones because of the constant oil leaks on the zoom brakes.
