I assume you are changing the brake pads, either a vice, really big channel lock and steady pressure,, a c- clamp, or the proper tool to do it and made for it, it's a cheap tool worth it's weight in gold... like a c clamp that has a flat surface on it and a squeeze handle... Anyway you do it, slow steady even pressure , take off the cap on the brake resevior, and clean any mess that might come out of there....
Use a "C" clamp to fully retract piston into caliper body
Clockwise to retract piston into caliper body
Use a "C" Clamp to fully retract the piston into the caliper body
Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body
Rotor "Out of Round" when rotating "High" spot will cause piston to retract into caliper body
Remove caliper mounting bolts Slide caliper off rotor Use a "C" clamp to fully retract piston into caliper body If parking brake is used on this caliper piston is threaded and a special tool (not expensive) is required to thread piston into caliper body
If it is the front brake use a "C" clamp to retract piston If it is the rear and the parking brake is used by this caliper piston is threaded and a special tool (not expensive) available at Sears or auto parts to "screw" piston into caliper body
Remove wheel Remove caliper mounting bolts Slide caliper off rotor Use a "C" clamp to full retract piston into caliper body Replace inner and outer pads Re-install caliper PUMP BRAKE PEDAL TO SET PADS AGAINST ROTOR PRIOR TO MOVING VEHICLE
Just a "c" Clamp to retract piston into caliper body, and a 3/8 Allen socket/wrench to remove the caliper bolts
