This video is a lifesaver. I’ve always been poor at adjusting V or U brakes. Now I have a much better idea of what to do. The BT-2 tool is essential for this job. Thanks Park Tool.
Great video, I was able to easily diagnose and fix my u brakes after watching. I still have the original 5 piece park tool pocket tool I bought with my first BMX in the 90's, and used it to perform the adjustments needed. Thanks a lot!
@@brandonaskari well your friend is stupid. Thats means its the ubrake type, the brake system you are watching in the video. No brakes is called brakeless. Simple as that.
I’ve tried everything in this video on a new brake setup but they still won’t grab enough to stop me. I can pedal through when I’m pulling the brakes my hardest. Do you think it could be the brake cable just being a cheap one?
This style of brake on a BMX bike is notorious for bad braking. The design offers poor mechanical advantage. Good quality housing (stiff) can help a little. Just a new cable alone might help a bit, but don't expect a great stopping brake afterward.
@@silentsilence5785 You could go to Cantilever brakes but that would not be a worthwhile change. I would stick with linear pull brakes if you want decent stopping power.
How does a person quickly loosen the front U-brake to allow the front wheel to be removed, say for example, putting a bike in the back seat of a car prior to a trip?
Disconnect the cable at the caliper pinch bolt. Now move the arms by hand and see if the brake caliper spring seems weak or strong. If the arms feel normal, the issue is in the cable and housing.
I've got a vintage mountain bike from 1988 that has a Shimano Deore U-brake under the chain stays. It has a short straddle cable that the main brake cable pulls on with a yoke to apply the brakes. Will a BMX U-brake work on this bike? It looks like the straddle cable doesn't have a quick release method.
The mounting system is the same. The common BMX brake does not use the straddle wire, and that gives them horrible leverage. It might fit but avoid it if you can.
@@parktool Thanks for the advice. I got the Shimano working again. The notch in the adjusting washer was worn and the tension adjustment screw was probably slipping under it and lifting it up instead of rotating it to increase tension. I ground the washer notch flat and the brakes now work again. I just got done with an hour long ride and now it's time to use my favorite Park tool - the BO-1. :)
Their somthing strange about your video your bmx bike chainwheel drive is on the left side of the bike.I wonder rhe chainwheel the left work as the right.

thanks to you I am now an expert at fitting and adjusting U Brakes! 🤙👊🏻
Best bike brakes how to video ever. So well explained I finally understand how to set u brakes up properly. THANK YOU SO MUCH!!!

Thank you! Was really stuck whilst installing onto my bmx. Turned out I was turning the tension springs the wrong way. 👍👍👏👏👏
I have been doing these repairs for many years; these videos are fantastic. Always something to learn!
This was super helpful and I was able to adjust my brakes. I love Park tools and these videos! keep 'em coming.
I have 2 GT performers and my brakes are always giving me problems I found this very helpful thank you I infact like the video and subscribed
Very good directions for this older brake style. Thanks Park Tool.

Perfect, just got a new BMX bike and I don't remember this tech been on disc brakes for decades now lol.
What is a u brake? My friend said that means there is no brake so u have to use ur feet

Man, these videos are just bike mechanic porn... Thank you Calvin and Park Tool!
Easily the best brake video. Thanks for sharing'
Awesome tutorial!
Hello! My question is that can a REAR U brake work/install on my Front?
My local bike shop guy it SHOULD fit maybe.
Restoring a 7 year old Sapient 24 Titan, looks like it needs new brake pads and spring tension is poor. I can fix it now thanks!
are the spacers supposed to be in that order
Can you tell me what brake this is? I can't find this model with the barrel adjuster.
That is a Black Ops U-brake. The barrel adjuster is at the lever on these styles, not at the caliper.
Super informal
Thanks. Now my u brake is perfect.
Do U-brakes use a regular-pull lever and not a linear pull?
Regular
I’ve tried everything in this video on a new brake setup but they still won’t grab enough to stop me. I can pedal through when I’m pulling the brakes my hardest. Do you think it could be the brake cable just being a cheap one?

can i swap out my linear pull v brakes for u brakes on my se big flyer?
No. The pivot for the V brake is below the riim. The U brake pivot is above the rim.
@@parktool so is there any other type of brake i can use other then the linear pull v brakes on my se big flyer? i dont want to switch it to disk.
@@silentsilence5785 You could go to Cantilever brakes but that would not be a worthwhile change. I would stick with linear pull brakes if you want decent stopping power.
Awesome!

Deflate tire
Push calipers against the rim and pop the cable out
Youre a pro
My cable doesn't go back after a squize the lever on the rear brake The pads stay against my rim. Do you have any idea why that is?
Disconnect the cable at the caliper pinch bolt. Now move the arms by hand and see if the brake caliper spring seems weak or strong. If the arms feel normal, the issue is in the cable and housing.
Thanks, I didn't know how to get tension back when one side went limp and pressed into the wheel.
This is awesome thanks a lot

How much price the break in Bangladesh.
Cool
How abt the back I need help
Can you remove all the tension in my marriage. ?

BMX bikes can have a Left Hand Drive transmission :) It works the same, and can be useful when using pegs
Yes, we were hoping someone caught that!
