I took the brake calipers off a truck that hasnt been moved or drove in a long time for my 95, anyway i took them off to paint and to replace the brake pads. My problem is that i need to compress the cylinder just a little bit to get it to go onto the rotor. I tried beating it and putting a c-clamp on it but no luck. Do you guys have any other tricks or just find some different calipers? Thanks.
