So, I have a set of Tektro Oryx cantilever brakes. They've been used (and abused) off and on for a couple of years now. I just took them off to replace the brake pads. But now, my front brake set doesn't "spring back" when I put the spring into the middle tension hole. I have to put them into the top-most tension hole to get any sort of spring-action. Now, my yoke angle is 'flatter' than in the rear, where I am using the middle tension setting.
Just by looking at the brake arms taken off the bike, the front and rear arms both look similar (as in, the spring doesn't look busted and everything seems to be where it should).
Any ideas, besides just getting a new brake?
