Adjusting Noisy Disc Brakes on an Electric Scooter
HTML-код
- Опубликовано: 8 янв 2018
- It's quite common to have an intermittent rubbing/rasping sound on any vehicle fitted with mechanical disc brakes, especially on electric scooters.
It almost sounds as though something is not correctly aligned.
However the likelihood is it can be remedied with this quick fix.
NOTE: This procedure does not require adjustment of the brake cable. Only do so if there is slight pad wear or excessive play in the brake lever.

*The **Latest.Bike** Scooter was everything I imagined. I’m 6ft4 200 lbs and it cruises perfectly… worth every penny!!! Thanks Gotrax!!!*
Seriously appreciate you keeping it short and sweet without a 5 min intro. This fixed my issue on my Vsett 9+ in under 5 minutes.
Thanks very much Logan! Glad to hear, hope it continues to work ok.
I’m trying to fix mine but the bolt is TIGHT as hell and I can’t move it for nothing, have you experienced the same thing?
I had this issue. what happened was some idiot in the assembly factory got a little to excited with the bolt driver. I had to have my local scooter/bike shop take it out with an impact drill. (my biggest advice for scooter people is buy your scooter from a local shop so you can always take it back for repair)
@@Logan-jb3uo Thank you for the advice, very helpful but I got the bolts out on my own. After getting them out, seems as if someone got lock tight and dipped the bolts in it haha.
@@v6_stone511 oh yeah man I'm sorry I didn't even think about that. If they used locktight then they probably recommend re applying on that bolt then. I have a Vsett 9+ so some bolts get locktight some do not. My rule of thumb is if was on it before re apply again.
Thanks so much for this great vid! Helped me HEAPS with my brakes! I had no clue how to adjust them. Easy as pie. Thanks again!
Thanks so much! This fixed my out-of-the-box xiaomi knock off! As you said, its really important to keep the caliper in that sweet spot while tightening. I had to redo it a few times but finally got it. Thanks again!
Thanks so much. You might have to repeat the process. But I hope it works and stays working. Cheers.
You made an issue I had no idea how to fix completely solved with very little effort. Thank you so much.
Hey thanks so much. Appreciate it.
Thank you so much for this!! I knocked my disc on a kerb and the sound was so loud, it has been bugging me for weeks. But amazingly, this fixed it! Thanks again🤗
Really glad to hear!
Respect my brother you helped me now I can go inside my room with my scooter without making so much noise bless up fam one love
Ha! Excellent stuff Jeffrey.
Thank you for this video! My scooter was making a noise new out of the box this Christmas. I was able to follow your video and adjust the brake caliper, found the sweet spot and the noise was gone. Thank you so much!
Glad it helped!
Damn! That was perfect. Super clear explanation - cheers!
Very good to hear, Vincent. Many thanks!
Thank you- I’ll try this tomorrow as it’s 1am now. I have a straight out of the box $1500 nanrobot D4+ and have this issue on the rear. I tried the rear bolt but didn’t touch the front. I’ll try it and hopefully it’ll fix it otherwise I’ll have to open a customer service ticket as the rotor isn’t bent
Good luck, cheers!
@@marcusoroberts never saw your reply, sorry haha! Your method worked and I have 400 miles on the scooter now and in a couple more hundred it’ll be time to replace pads and I’ll probably have to do this again haha!
My Scooter was left outside on its stand I came back outside it had fell over and ever since I had this feint grinding sound coming from the brake disk. I tried everything I could think of including removing the break cleaning the brake pads taking the tire off checking the bearings and I could not sus it out until I seen your video and have to join the appreciation club in Thanking you ever so much cause it was getting worse and worse and was stressing me out more and more and really I was convinced it wasn't a simple fix like that. Once again Thanks Very much Marcus Roberts 2 years on and still assisting people.... Amazing.. I was about to box it away and get it checked out and that is a total nightmare
Very kind of you to say, Mark. Thanks and have a great day.
This worked like a charm on my HiBoy S2 Electric Scooter. Thank you so much!!!
Really glad to hear it!
Thank you! It helped me fix my scooter!! Amazing no more scratching noises
Thanks for the comment, much appreciated. Cheers!
Thank you, that was way easier than I thought. Great video!
Thanks for watching! Hope it helped.
This is the only instruction I found on youtube that works. Love the simple explanation although I messed it up the first time. My brakes are on the left side of the wheel and I was still tightening the left nut first (the front) which does not work. Need to tighten the rear nut first with the brakes engaged.
Thanks so much for saving me time and sweat. I even asked the vendor for instructions and it just talks about loosening the nuts and wiggling till it doesn't make noise. Well, it keeps making noise no matter what with those instructions.
Hi David, thank you for letting me know. Let me know if you get problems with it. I can't guarantee it's a perm fix, and may have to repeat after a while. It's a common issue with all mechanical disc brakes on scooters. Cheers!
I never had experience with scooters or disc brakes before so good to know it does this a lot. I found another video that adjusted the front nut first which didn't work for me. ruclips.net/video/3HsH59EkaKk/видео.html Maybe I just wasn't patient enough?
You just helped me out so much, thank you for making this video.
More than welcome James. Hope it works. Cheers!
I was going a little crazy trying to figure out the source of the noise on my new Mantis Pro SE. Thank you so much for posting this! Issue solved! 👍
Zach, thanks. Hope it helps. You might need to readjust once, but it should work permanently. Cheers mate.
Thank you. I just bought one and had the exact same problem. It was very easy to fix it using your video. And I am the worst person in this kind of things..
That's really great news Hugo! Thanks.
Thanks for the vid, I got mine sorted in a few minutes. You took that hit like a champ as well lol.
Thanks Steve! Hope it continues to work ok. Cheers!
Thank you for this advice. Recently purchased a Solar P1 and it was the same fault out of the box. Making exactly the same noise when turning the rear wheel. Will adjust the caliper.
Thanks and good luck.
Thank you, worked perfectly on my brand new scooter.
Hey thanks very much for feedback. Much appreciated!
Awesome. I was looking into fixing this is as well in my new electric scooter and I think I have the same one as you on top of it. Can’t wait to try this out. Thank you
Thanks Stephane and hope it goes well. Keep us posted.
Thank you very much! Resolved the issue very easily with this instruction
Cool. Stay safe. Cheers!
Thanks mate, just did this repair on my lighting V2 (dual pro in UK) worked perfectly:)
Glad to hear!
I have the SAME problem with my hummer. I didn't even notice the front wheel was not turning free. This should EXACTLY help me to fix it MYSELF. THANKS ALLOT!!!
Hi Geoffrey, too kind! Hope it might help. Thanks.
Thank you very much for this video, I was going mental as I've just got a new scooter and was wondering why it was making that sound after one ride. Much appreciated 👌🏿
Cheers Michael!
Thanks so much just got my new nanrobot d6+ and had this problem but this fixed it! Key is to do the back first then the front caliper...just wow!...super simple fix.
Hi Kenny, glad to hear it!
Thank you, this helped me a lot with my new E-Scooter.
Thanks Kevin, glad to hear.
Awesome video!! You saved me so much time. Thank you! 😊
Thanks very much. Hope it will work for a while.
Thanks for info, was getting frustrated with the noise from my rear brake, saw this and bingo, thanks
Thanks for letting me know David. You might have to do it again every so often. It's just one of those things I'm afraid!
Thanks for the great explanation, it was very helpful!
Thank you ~ hope it continues to work.
I have the same issue on a brand new one myself - will try this. Thank you!
Good luck, hope all goes well!
Thanks buddy, just sorted out noisy front brake on my nanrobot d4+ 💪
Really glad to hear. Stay in touch and stay safe.
Awesome. Took 2 minutes and saved me a trip to the bike shop :-)
Thanks very much Kasper, nice of you to comment. Glad it might have helped a little.
This is perfect! I tried it on my m365... Worked 99%
Thanks for feedback. Cheers!
thanks so much it was embarrassing to have a loud rubbing brake in a crowded place
thanks :D
Glad to hear it, Humaid!
Thank you sooo much for this video, you helped me on my xiomi m365 and future scooter I plan to get! You got my sub!
Thank you Chris, much appreciated!
@@marcusoroberts No problem much appreciated!
Awesome, thanks a lot! Just got my Furo Systems Fuze, and its doing exactly this... so fingers crossed it will fix it.
Hope it works. Let me know how it goes. Good luck!
@@marcusoroberts Worked perfectly... The back wheel was really easy, exactly as you described.
The front was a bit more fiddly, pulling the break and tightening the 1st screw didn't work, it actually made the rubbing worse.
Instead I had to loosen both screws, then manually adjust it, constant small tweaks near 1st and 2nd until it was not rubbing on either part... then incredibly carefully tighten them up!
@@EViL3666 Great workaround! Thanks for sharing your experience Kelvin.
Nice one Marcus - thank you. Insofar as I'm aware, the rear/brake flashing light MUST be active in order for regen to engage if it's on the scooter (a [micro] switch engaged with the use of the brake level), so always ensure that not alone is the brake fully functional but also that circuit remains active, after the adjustment. Happy travels.....
Correct Dave, for most Chinese scooters that is the case and the controller(s) recognise that
@@marcusoroberts Thanks again Marcus - always good to learn something new every day. Take care.......
@@daveroche6522 stay in touch Dave, take care on your scooter
@@marcusoroberts Wildo Marcus. Y'know, years ago (when I was around 12), my favourite part of Saturday mornings (after a bit of football while avoiding doing school homework) was doing the car checks with my Dad - he gave me some of the best advice I've ever heard (a wise man, with a fantastic sense of humour - still miss that lad, R.I.P.) - "After you've done all the checks, when you sit in the driver seat, always - always - make sure you're comfortable - if you're not, you'll get distracted. Which is dangerous - the same when you cycle - you always make sure you're ok before you let rip". How true - I stopped driving years ago (never really took to it, so don't need/have a car now - my trusty eBike is perfect for my needs) but I realised that when cycling (and therefore scootering), it's best to be certain we're physically/mentally good and try to achieve a far greater sense of situational awareness when we're travelling - plus the realisation that sometimes simply stopping, dismounting, crossing the road then continuing on the bike/scooter is the best/safest option - nothing wrong with that!. When scootering, always - always - bear in mind others also use bicycle lanes/roads etc. It makes sense. And remember kiddies - "No helmet? NO WAY!". "Go n'eirigh an bóthar libh, a chairde" (yep - that's todays freebie Irish lesson). Enjoy the trip!
@@daveroche6522 lovely, very cool. Enjoyed reading that. Thank you for share.
Dam handy vid thx & hope the bump healed quick ;)
Thanks, very kind of you. Cheers!
Thank you!!! This saved me! I thought my brand new scooter was broken
That's great news Ellie, take care!
Perfect it works great video keep it up
Thanks, very kind of you! Cheers.
Thanks a lot, fixed the same issue on my Xiaomi M365 Pro. Awesome!
Really happy to hear it. Take care and cheers!
Thanks mate, you're a legend!
Kyrill - you are too kind sir - thanks!
good and helpful video,thanks
Cheers!
Marcus i have a motorino xpb sometimes a god awful noise comes from the back wheel and the bike stops. It sounds as if something has got caught in the wheel spokes. I start it again and it goes but I feel every time I accelerate some catches for a moment and then it goes ok. I would really appreciate your help
Life safer just out the box checking before use I had no idea what I was suppose to do thanks to you I fixed my disc brakes 😁👍
Thanks Benjamin, glad to hear it. Cheers!
i watched another video on disc straightening my disc was damage but tweaked on it lol after 2hrs i turned pro mechanic haha.
@@ben_eighth Cool 😀
Thanks so much I was going crazy as I just got it new
Cool! Thanks for letting me know. Hope it continues to be ok. Cheers!
Me too. Mine is only 5 days old!
Your dog have perfect timing lol
Thank you sir! Knowledge gained!
Thanks!
I have this issue on a new hiboy. And it comes and goes. It has a mechanical break and handbreak. When i clasp the handbreak once or twice it goes away. But comes back. Don't want to have to unfasten any bolts and make things worse.
i got my scooter today and noticed when i hit the throttle the rear disc brake makes a bell noise?how can i fix it they are hydraulic brakes...
And it works! Ty!
Thanks I did exactly what you said and it works🎉
Great to hear! Thanks for letting me know
It works man many thanks 😊
Great stuff. Let me know if you have any problems. Cheers!
My scooter isnt making noise when it just moves, but rather when I'm braking, will this still work?
Brilliant information - thanks
Thanks Tim, very kind! Hope it works.
@@marcusoroberts it did, I always tighten both bold at the same time and the sound is still there, but doing it as you say works - thank you
@@timpriestley8997 great stuff Tim, thanks again for letting me know. I do so appreciate any feedback. G'weekend to you Sir.
very very useful video, my spider desperately needed that
Thanks for the comment Tommy!
Bought my 1500w one and seems to squeak something on the back tire, can wait to try once home 😅
That will probably be the brake caliper. They all need slight adjusting even when new. Hopefully my other video on brake adjustment might help. Good luck!
Hi got same problem on the front it’s spins half then stops spinning and is hard to turn wheel I think it’s slowing scooter down too.Its a qiewa 800watt hummer looks just like yours I got new brake cables fitted the cycle shop said the brake calliper and disk is the wrong side of the bike as the back one is on the right and front on the left is this meant to be I bought it bran New a year ago from amazon for a £1090 not cheap thanks if u can reply.
Hi Steven, it's normal on scooters like these to have diametrically opposed brakes i.e. rear and front brake on different sides. This is down to balance and also ease of cables with 2 motors. It's more likely they still need adjusting.
When I ride my scooter o get a weird loud speaking noise but it happens when I put weight on it if I run the scooter without weight it's fine
This fix didn’t seem to work for my new Mantis 10. Is it ok to continue riding it even if the front wheel makes a slight scraping sound w each rotation
Sounds like distortion in the disc or dirt in the pads. I assume the pads are not worn? As long as the scooter stills stops safely and the noise doesn't bug you, should be ok. Cheers.
It worked thank you.
That's really great to know. Might not be a permanent fix, you may have to repeat the process. Cheers!
Perhaps a silly question, is it the rear bolt on the front caliper as well? Thanks.
No such thing as a silly question. Yes the same applies to the front disc. Rear bolt first . Thanks for asking.
Awesome video mate. You spared me some unessesary work and bad language. = )
Glad it worked. Hope it continues to be ok. Cheers!
I am having issue on my scooter, every time I turn on the lighting the motor does jerking and run very rough on the front wheel, but when I turn off the light it runs just fine. Any Idea?
You could try swapping the controller output cables so that the rear and front motors are opposite. This will isolate whether there is a problem in the front motor, the wires or controller. There might be a short circuit between the wire for the light and the front motor power. Let me know if you find the problem.
hi marcus,. i got one of those chinese scooters with front and rear discs, front breaks are ok, however when i adjusted the actually calipers and brought them closer, they would rub badly on the rear disc, when i loosened them up a bit to leave space for the disc between them, they are then too far away for actual friction of the disc,i am currently riding with only i disc break that actually works, how do i go about fixing the rear one
Hi Alon. It's only ever the rear brake that causes the problem. Ok I will try to assist. Slacken off the 2 bolts on the top of the brake caliper enough so that it moves just little. Squeeze the brake lever and keep it squeezed (might need another person) and then tighten the rear bolt but not overtighten so it doesn't move, just to keep the caliper from moving. Rotate wheel backward and find the sweetspot where the brake grips and doesn't make a sound. Then tighten front bolt all the way and return to the back bolt and retighten.
If it really doesn't grip the brake discs at all then you might have to do cable adjustment. Start with the caliper end and pull the cable through until you the point where the wheel becomes slower to rotate without pulling the lever. Set it there then micro adjust at the lever.
Please do shout if I can help more. Don't go riding with only one brake mate!
@@meroawrr yes. It sounds when the wheel rotates that the disc is distorted but it really isn't. You hear the 'twirrling' sound? It just needs 'recallibration'. It rubs, then it doesn't, then it does. It's the minor tweak the caliper needs gentle adjustments.
great you solve my annoying mysterious sound
Happy to hear that Ferdz!
Great video! It worked for my rear wheel, but I'm still stumped on the front wheel. So the problem is the disc is rubbing on the non adjustable side and no matter how much I push the break to the left it still rubs on the left pad. Is there a way to fix this or is my scooter just faulty?
nevermind, I was able to fix it by truing the disc!
Sorry for not getting back sooner, but glad you fixed it!
Hello Marcus, thank you for sharing. we have the same scooter viper duel 2000. but i have a problem with mine, the front wheel is a little bit wiggle when i go 50 kph above it's very hard to control because the vibration of the front wheel is strong. Could you please help me about this. Thank you very much in advance.
Hi Wenceslao, is the wiggle definitely from the wheel or is it from the handlebar stem? Also, is it a constant sideways wiggle above 50 or a knocking/rumbling thing. And does it happen with the front motor on and off? Hope that makes sense. I will also do some higher speed testing at the weekend to see if I can replicate. Thanks bro'.
Marcus Roberts i tried to check it very carefully yesterday and i found out that the rim is aligned but the tyre and the disc rotor are wiggled. So i think i will change the tyre and try to align the disc rotor but it's a lot of work. What do you think the best idea? Do you know where i can buy the tyre if ever? Thanks for the reply bro.
Hi Wenceslao, did you resolve this problem? If not, did you try putting the scooter on a block and turn the front wheel without power, and also turning at high speed with power? Does the problem only occur under load? I think if the tyre has around 45psi and has no deformities then that's not the problem but you can get 2.50 x 10 tyres here:
www.ebay.co.uk/itm/Kenda-Tyre-2-50-x-10-Inch-4-Ply-Rating-Scooter-Moped-Classic-K-313-C-10-001-NOS/263512017072?epid=17010288938&hash=item3d5a8a48b0:g:DG8AAOSwUn9aF19F
I think 2.75 x 10 tyres also fit and are slightly wider profile.
Perhaps the wheel might need balancing if the wobble is high speed? I don't think there are places you can do this professionally but you could try to balance through trial and error.
Very helpul thanks it works in my scooter
Thanks for watching Scott, glad it might have helped!
Marcus Roberts no thanks to you it helps a lot in me,more helpful reviews for scooter...more power to your channel.
Cheers Dude!
Glad I stayed right to the end haha is your head okay lol
Cheers!
My xiaomi m365 makes that scratching noise when riding but from time to time and it doesn't affect the performanse, bought it 2 weeks ago and a use it to go to work. Can I leave it alone without adjusting it ?
Yes you can leave it. It won't affect breaking performance or damage the disc. It's only suggested because the noise is annoying.
@@marcusoroberts thank you very much sir, God bless you.
Hi what could it be possibly be we hear like a clunking noise coming from the rear. It already had a new disc break when come back from repair from the company but they said it could slightly warped break disc. We can’t notice anything warped. You only hear it when riding not on work bench accelerating
Do you hear the noise when breaking?
@@marcusoroberts the noise is constant. As soon as start riding. And goes quieter when slowing down letting of the accelerator

@@marcusoroberts ruclips.net/user/shortsaXrNUZDwneM?feature=shared
thank you
Why would you taste it rolling the wheel in the opposite direction of when it's running on the road? (just want to understand)
@Pedro, it's a good question. The way the wheel rotates forward you only check the front of the brake pad touching the disc first. This is usually over biased and makes the squeal sound. Rotating the wheel backwards ensures the 'negative toe' or 'toe-out' is neutral. The pad should hit the disc at the same time. Hope it helps.
@@marcusoroberts Yes, thanks for answering
Marcus do you know by any chance what could be making a rear wheel when spinning it looks like its wobbling could it be the tire or the rim.. i know it may not be in this subject video but as you are at the rear end of the scooter you might be able to help
Thank you once again
Oh by the way merry christmas and a happy new year hehe
Hiya mate, you probably already tried it, but have you checked that the hex bolts on the hub are tight and evenly torqued? Most hubs have 6 hex bolts on the inner and/or outer rim. I heard of someone who described the same problem as you, and one of the hex bolts was not quite tight. I guess the axle on the hub is secure too and the tire is about 50 psi? It's very unlikely to be a warped wheel rim. Let me know if you find the problem bro'.
Thanks marcus for the quick reply and info ive just checked it out and all the screws and bolts are tight at the rear side of scooter..
I will give it another over look some other time maybe i could of mist a srew or bold something
Thanks once again
All my best regards to you
Booboo Bambos did you find a way? Because I’m also having the same problem as you
Sorry to hear that. Do you have a scooter with a hub motor and if so have you checked the 6 hex bolts keeping the motor tight? They can work loose and have to have even torque Sorry to ask the obvious. Let's work through this together.
If you've done hundreds of miles it would be the bearings, but it's more likely to be an incorrectly fitted tyre. Is the tyre inflated to 50psi?
its work thx 👍🏻
Thank you so much
Thanks Pranav!
When i squeeze , the break just doesn't clip anymore , isit because i ran out of brake pad?
It sounds more like the cable needs adjusting. If the brake pad is worn, it would probably make a squealing noise. It wouldn't hurt to change the pads anyway because they are really cheap. Good luck!
Mine just makes a noise every now and again when riding is something faulty or do I need to adjust it
It's worth adjusting the breaks on a regular basis anyway, but you might just have some dirt on the pads.
@@marcusoroberts I was suspecting the pads avovo are a good company tho straight away they sending new disk brake and pads
I wonder how you fix brake squeal? When you brake hard and there’s this high-pitched noise weeee
If you're brakes/scooter is new that's normal
If not get new pads and mabe also new disks
I’m more fascinated by that iPad on your wrist 🤣
No, it's an Android watch. Would never use any Apple crap. This is a standalone watch that has it's own SIM. Forget the iWatch 🤣
you are GOD ! thanks so much !
Thanks Ivan, very kind of you. I hope it continues to work for you. Stay safe dude!
ive tried doing this and it is still being noisy. any tips?
I guess if this doesn't work then the discs are distorted or the pads are worn.
How about noisy Hydraulic brakes?
What happened my back break stopped working.
Give me a little more detail so I can help. You say your 'back break stopped working' is like saying the engine on your car stopped working. Give me some clue so I can help!!
mine squees really weird like its engine or something help
I have a chaos 1000w electric scooter and I have the same problem thanku
Great stuff Nitro! Cheers.
I wish i watched this video when i first got my escooter, i have 600 miles on mine and they're noticable worn unevenly.
Hope it works ok for you dude
Your welcome
I have this noise from my front wheel and I think it’s slowing my scooter down as it has slow accel and my friend has faster accel than me
Is it a dual motor scooter or has it a motor on the front wheel? if yes, then you need to run it on a block to see if it turns the wheel as expected. Then turn the front motor off and turn the wheel and check for friction. It will either be the brake or the bearing. Detach the brake calliper an see if it still rubs, then it's the bearing.
@@marcusoroberts it is a back wheel motor it pulls from the back wheel but the front wheel disc brake and pads are touching i think this is slowing it down
@@BigLen904 OK, so now you know it's the brake, just follow the instructions for the back wheel. Its sounds like your brake seizure is more extreme. Slacken it all off, but don't slack the cable too much. Clean up grime and reassemble. It is definitely a calliper alignment issue.
@@marcusoroberts i am going to do this now thank you very much, do you think this is why the scooter was slow on accel and bad at top speed because the brake was slowing it down?
@@BigLen904 what is the make of your scooter out of interest? Like I said, Put the scooter on a block and test it. Turn the front wheel. Unscrew the bolts for the calliper. Does the wheel rotate quicker? The brake pads will last for at least 2 years unless you drive 50 miles a day. The calliper might need adjustment.
It the scooter ghost, You wanna bless that scooter with some holy water before you hit top speed on it, lol, Only joking, At least the light didn't blow up on your head, Having issues with my brakes already an only done about 60 70 miles, How many miles do the discs usually last for on the electric monster scooters anyway's?
But you explained this easy, Pity about the light falling on you tho, I will be honest had a little chuckle off that one soz, lol...........
Hi Matthew, the discs will last forever unless they've become contaminated by grease or oil from the road. The pads should last 500+ miles
Didn’t work I guess I’ll send it to the shop I have a warranty on it that’s good
Sorry to hear that. Most cases works, but not guaranteed.
Lol he he ha ha x
I get a grinding noise when I brake with my Aovopro ES80, it’s brand new any ideas on how to fix?
Are they mechanical or hydraulic brakes? Shouldn't be too different, the principle is the same if you follow my vid.
Is it possible to loosen the Calipers if the wheel is a slight wobble ?
Do you mean the wheel wobbles when you ride it without braking? Does it wobble all the time?
@@marcusoroberts yea all the time
