Is this caliper OK
I was going to clean up and paint my front brake calipers, but found a alot of corrosion on the outer part of the caliper piston. Is this OK, or will it leak? Should I rebuild the calipers? I'm thinking that part of the piston doesn't go into the caliper any further, so it'll probably be fine, but I want to make sure before going to the trouble of cleaning and painting etc. Also, as the everything is taken apart ... how do I get the piston out further?
... can't take credit for the graphic ... but it's cool, ain't it?
