How to adjust the cantilever brake correctly?
Hello, I own an older bike with cantilever brakes. Unfortunately, the front brake isn't working properly. After applying the front brake lever, the right brake shoe stops, drags on the rim, and doesn't return to its original position. The left brake shoe works as it should. What could be the problem?
It is a Shimano cantilever brake, with only one spring adjustment screw (left side).
Did you remove the brake arms yourself? In some models, the lower part in which an end of the spring is made of plastic and broken. The feather won’t stay where she should be. Look at this! This is the only real damage occurring at Shimano-Cantis.
If it is, the brake has finished. And good, because then you can afford this as a replacement:
XLC BR-C03
(I don’t think, because my Cantis are a little better, without plastic, and work perfectly.)
Hello Felix, you’re right. The gray spacer made of plastic of the right brake shoe, in which the spring is located, is torn. Will replace him immediately. You know, too. 😉
Thank you.
You usually have three holes on the frame to choose from, into which you could put the feather. Did you pay attention to that?
Yes, brakes were exchanged, worked as good as possible, took the middle hole.
It is usually located on stretched bases for the brake arms.
Finishing, cleaning, lubricating, assembly. Lubricating and testing for ease of use.
Once I’ve already done, both brake shoes have been removed from the base, ground with sandpaper, cleaned, and then reassembled. Unfortunately, as before, the right brake shoe does not go into the initial position.
The problem is not the base, the bearing is in the brake. Mostly a brass jack. It is riveted in most cases, and therefore bad to clean/oil. If there are rust approaches, only the exchange helps.
Have the solution, the gray plastic spacer in which the tension spring is located has a crack. Will replace him, then it should work.
that doesn’t sound good
oh weia best buy you a new one because with shimano I never did good experiences
