Great channel, most of contents were easy to understand and follow 👍
Thanks very much ! :)
put grease on the bleeder screw threads to prevent air from getting sucked in.
Thanks for the tip 👍
Naw use Teflon tape
I love the feeling of passing air bubbles! fffrrrrappp! Lol!
Neat little tool.Thank you for sharing.M
Cheers :)
So far it worked for me on my rear disc brake. I had no grease so I used some other grease to put in.
By far had no air going back up after releasing the foot brake.
Only issue I had was that the disc pad was stuck as it was being pushed by the cylinder, I had to set it free and unstuck using a flat head screw driver. Once it did let go, the brakes was more responsive and not spongy and manage to pump all the brake fluid and topped it up until it all cleared out.
Old fluid had black particles probably from the hose line or the rubber grommet on the cylinder plastic cap.
1:55 Do not put cylinder cap back on till all bleeding is done !
Soundest one-man DIY method though (affordable vacuum bleed kits are useless), so good video.
One point is important to mention however.
It's not enough to just pump the brakes till you see no bubbles and a full continuous flow through the bleed tube. You can often have this in 2-3 pumps of the brake pedal - yet still have a spongy brake pedal clearly needing more bleeding.
For bleeding with a one-way valve, I've found that 10 pumps of the brake pedal are needed for each nipple with a top-up of the reservoir before each. It may take even more pumps if the brake fluid is being renewed.
Thanks for the tips ! :)
Thanks for tips. So basically just pump brake atleast 10 times for each caliper and top up fluid for each and we good?
@@grilledchickenwrap Yeah - except if renewing the entire system. That could take more, pump till real stiff.
Fluid is really inexpensive and can't really be kept in an open bottle. You may as well keep flushing until you have one left. The fluid in this video looks clean but always checking to see what the water content is (a £10 tool) to see if a full flush is necessary.
Try the brake bleeder that uses the car tyre. Not expensive and works well. I tried a vacuum hand pump one and that was rubbish.
Beautiful
Thank you
this is a great method, thanks
Thanks for watching ! :)
Is it worth cutting down the check valve to caliper part of the hose to aid in priming the valve?
I bought one of those valves but it leaks
nothing beats the two person method👍👍
ah, so with this one way tube you dont have to open/close the drain screw all the time. Nice.
1:08 what is the meaning of a cheap one way valve since the fluid turns back as we see?
those are bubbles that haven't pass the valve yet... what you're seeing is the bubbles moving, not fluid going back through the valve.
I seen bubbles go back through the valve
@@UNKLEWHEELIESON And they are then pushed out in the second press of the pedal. The only reason there was that initial backflow was due to air in the system.
@@LBCAndrew ok...im learning
I assume I don't need to open and close tbe bleed nipple like I would normally do if I didn't have this tube
No you shouldn't need to open and close the bleed nipple when using these
My valve stopped working after doing the first caliper. Instead as soon as the fluid hits the valve, the tube pops off the nipple from the pressure. It was facing the right direction. Can they get air locked or something?
The valve must have failed internally. Surprising, considering it's such a simple design
Where'd you get the one-way/check valve?
I bought it on ebay :)
I have some questions, I'm about to change my rear caliper, when I put the hose on the nipple, do I remove the brake resevoire cap or not? Do I pump the pedal all the way to the bottom or like some people say put a block underneath the pedal?
You should leave the cap off as you will probably need to top up the brake fluid reservoir as you bleed the caliper. I always push the pedal all the way down. I've never heard of the block under the pedal idea
Get the brake bleeder that uses a car tyre. It uses air to fill the reservoir and pushes the old fluid out. You just need to open close the bleed valve. Nice and easy. Non of this one way valve, pumping on gas pedal...
@@kingmonkey88 yip, and 4 times the price.
@@antonywilson4539 Nope, something like the Gunson Ezibleed. Less than £20. Unbranded versions are even cheaper. Makes brake bleeding so much easier.
@@kingmonkey88 You mean £40 don't you?
There is no need for the one way check valve.. If you just submerge the hose in the bottle, it won't allow air to travel back. Also a cheaper alternative to self bleeding.
The check valve is just an additional layer of safety since if you screw up and get air in the system, it can get into your ABS and cause a big problem.
"open the screw half a turn".... It's better to open it a quarter of a turn like you did in the video, it's critical not to open it too much as you can pull air in the threads when you lift off the pedal.
If you put some heavy grease around the bleeder, it will help seal it so air is not sucked in if its a loose thread.
i alreadly order this item..
i try blow air with my mouth to that valve.. with correct arrow.. but why the air can not throught that valve 😅
It might need a bit more pressure :)
@@screwsnutsandbolts maybe.. thanks.. i will update later

Great concept but I wouldn't use it. You can see air in the tube which is more than likely being sucked back past the threads of the bleed valve, this is the reason I wouldn't use the vacuum method either. If you're in a pickle then go for it.
use 1/4" teflon tape or silicone grease on the bleeder valve if yours are not tight...
The vacuum method is different. If you keep vacuuming by holding the trigger and then you tight the bleeding nipple while you still holding the trigger, you will be fine, as the liquid will going in one direction and the system will not take any air from the nipple.
@@arvacon Correct, I didn't make myself clear. With bubbles in the tube it's difficult to know where they're coming from and if the system is bled or not. Personally I prefer the pressure method, which also, in my experience, can help to dislodge air locks due to the speed at which the fluid can be forced through the system.
You didn't show us the other end of the tube. Incomplete instructions.
It’s up his ass bro common sense come on
This video pretty much proves the product (check valve) does not work as you can clearly see brake fluid flowing both ways through the device.
It's crap, a one way valve shouldn't allow anything to pass back but you can clearly see it does. Thanks for helping me decide not to get one! 😁
I think once the check valve got fluid in it, it started to seal. You can see the bubbles grow when the pedal is released indicating lower pressure. That could only happen if the check valve was sealing.
It is actually working fine. what looks like backward flow is the air expanding behind the valve. :)
It's a shame you're not smart enough to see what is actually going on there. Ignorance is bliss though eh?
