hi fellow cyclers,
I'm intending to put back on the road an old bike with shimano moutain LX (nowadays Deore LX family of components) parts and I'm having an issue with the rear U-brake. Basically, there is a spring system inside the brake housing but it doesn't seem to be effective at all as the brakes are not pushed appart when releasing the lever. Any idea why?
Also, when I unmount the brakes and look at the return spring, it looks just fine. Note that the springs are self-contained inside each arm (pivot?) of the cantilever, with no attachment to the studs/frame fittings.
Here's a link to a picture and description of this brake model.
thanks for any help!
EDIT: I found a post on the same brakes model linking to Sheldon's take on the U-brakes. got my answer on setting the springs but it still doesn't work, there's no elasticity in the mechanism... Might the brake be dead?
