Unlike the front calipers, pistons in the rear usually have to be rotated to compress them.
Use a large C- clamp to depress the piston enough to remove the caliper.
How do you compress the rear break caliper, pistons on a 2002 Sierra ?
Jack up and block the car remove wheel pry back the caliper pistons with out breaking the pistons then remove caliper and pads.Reverse to install and pump brake pedal until it gets hard.
I just did mine. Use a screw driver to press the brake pads away from the rotor and compress the caliper pistons back some so you can remove the caliper off of hte rotor. Losen and remove the bolts to the brake caliper. DO NOT DISCONNECT the brake line from the caliper! Get you a c-clamp and a piece of 1/4 board about 4 inches long. Once you have removed the caliper from the mount and removed the brake pads support the caliper with one hand. Place the wood over the caliper pistons and using the c-clamp place it over the wood and center of both pistons and other side of caliper to compress the pistons back into the caliper. Make sure you DO NOT PINCH the rubber boots on the pistons. Once you have compressed the pistons back into the calipers install your new pads and calipers back on the mounting surface and tighten the bolts back to torque specs.
Depending on the make/model/year of vehicle, you may have to get a rear caliper tool. Some rear calipers need to be turned to retract them.
you will need a c clamp to depress the caliper after pulling the brakes, first take the tire off second there are usually 2 bolts to the caliper remove the bolts third you will find the pads once you remove the caliper they will just snap in then you will need a flat surface to push agaisnt the caliper to depress it i usually use the old pad when you have finished you will need to pump your brakes in the car until the are hard.
Best to just buy a rebuilt caliper complete. Cost is about 20 bucks or so.
Remove the wheels, then the bolt that holds the pin that holds the caliper on. Drive the pin out then depress the piston completely in the caliper. Make sure to use the anti squeek grease or shims when reassembling it.
same as on all disc break pad changes, but you must have special tool to depress caliper. a c clamp will not work. must have tool to put onto 3/8 in. drive socket and turn clockwise and this will depress caliper. replace pads, bleed and this was the most challenging part of the job.
jack and support vehicle Remove wheel Re-intall 2 lug nuts to hold rotor in place Remove caliper mounting bolts (2) Slide caliper off rotor use a "C" clamp to fully depress piston into caliper body Replace inner and outer pads Re-Install caliper DEPRESS BRAKE PEDAL TO SET PADS AGAINST ROTOR PRIOR TO MOVING VEHICLE Re-install wheel
screw it in turn the piston clockwise and screw it in , only for rear brakes
To change the disc brake pads on a 2003 F250 you will first need to remove the wheel and tire. There are 2 caliper bolts behind the caliper which need to be removed. Then use a special tool or C-Clamp to push in the caliper pistons and replace the disc brake pads.
