brake problem - caliper not opening
I have an older Dia Compe brake caliper. When I pull the brake lever the brake closes, but when I release the lever the right arm stays closed/in.
I think the springs on the back are in the right position, I think the brake is functioning.
Any ideas on how to fix this? The left arm releases, but the right arm stays in and doesn't move off the rim, which is a problem.
