Thanks Dave. I just wish I knew everything the first time I did this... Or even the second....or third It's been a learning experience if anything. With the copper grease, I mean where the pad sits at the top and bottom. First time I changed the pads and re-greased the sliders, I thought that would fix it. I looked past the fact that I had to hammer out the brake pads because the build-up of rust meant they had zero room to move. Not having much experience doing brakes I didn't see what else I could do. Because of this they still had issues sticking. The next time I removed all of the rust so we were back to a smooth surface. Re-fitted, and I've had no issues since, other than this one calliper which I think may be the piston. But like I say, I'm not sure if I should have added a little grease too, to help the pads slide freely, and prevent rust building up again. Can the handbrake mech be removed with the calliper still fitted?
