Cleaning the bushing on an avid v brake?
I'm trying to put some life back into a set of rear brake avid SD 7 calipers that have become very gritty. I noticed that the rear calipers didn't want to spring back after you hit the lever. I took them off the bike and realized that the spring didn't want to move freely. I cleaned them off with some rubbing alcohol, squirted a bit of light weight "turbine oil" I have kicking around in them, and worked them for a bit and used a shop towel to wipe away the bit of grit that came out of them. They're smoother than they were, but it seems like the best solution would be to take them apart and clean the bushing out, as there's still a tiny bit of grit in there. Is there any way to clean the bushings out, or do you just oil them and hope for the best once they get gritty? (I could replace them, but they're only a year old, and I want to reuse them if possible.)
That'll teach me for riding in the winter.
