Try pumping the brakes...this is necessary after re-positioning the brake pistons...You either have a brake line leak...or your master cylinder is bad...try bleeding each side to remove any trapped air...be sure to recheck brake fluid level after bleeding...you can bleed at the brake line connection to each side...on each rear caliper...Hope this helps.
Inspect the fluid level in the master cylinder reservoir. Remove fluid from the reservoir until the level is lower then half way between the MAX and MIN levels.
Remove the tire and wheel assembly.
Install 2 wheel nuts to secure the rotor on the hub.
Remove the bottom brake caliper pin bolt.
Pivot the brake caliper body upward and secure out of the way. Do NOT disconnect the hydraulic brake flexible hose from the caliper.
Compress the piston back into the bore using a C-clamp.

Remove the inboard and outboard brake pads from the brake caliper bracket.
To Install:
Install the brake pad retainers and both brake pads into the caliper bracket.
Pivot the brake caliper down over the brake pads and into the brake caliper bracket. Insert the lower brake caliper pin bolt and torque bolt to 70 ft-lb. (95 Nm).
Reinstall the tire and wheel assembly.
Lower the vehicle.
Refill the master cylinder. Pump the brake pedal several times to seat the pads against the rotor.
Check the master cylinder level and add fluid as necessary.

Remove the tire and wheel assembly.
Install 2 wheel nuts to secure the rotor on the hub.
Remove the upper caliper mounting bolt.
Pivot the caliper down to access the pads.
Remove the inboard and outboard pads from the caliper bracket.
Remove the brake pad clips from the caliper bracket.
Compress the piston back into the bore using a C-clamp and the old inner pad.
To Install:
Install new brake clips in the caliper bracket.
Install the inboard and outboard pads in the caliper bracket.
Pivot the caliper up over the pads.
Reinstall the upper mounting bolt and tighten to 32 ft. lbs. (44 Nm).
Remove the 2 wheel nuts securing the rotor.
Reinstall the tire and wheel assembly.
Refill the master cylinder. Pump the brake pedal several times to seat the pads against the rotor.
Check the master cylinder level and add fluid as necessary.
If you are replacing the rear pads and are trying to retract the caliper pistons here is what you need to do. Use a piston installation tool in order to twist the brake caliper piston into the brake caliper bore. If you do not have the tool you can retract the piston by using a needle nose plier. Exert downward force and rotate clockwise until the piston bottoms out. Before installing be sure the two "U" shaped slots are at 6:00 and 12:00 Oclock.
In order to retract the pistons on the rear calipers you need to use a special tool that will rotate the piston in a clockwise direction.It may be possible to try to use a strong needle nose plier.Apply force against the U shaped slots on the piston and rotate clockwise until the piston bottoms out.Before you reinstall the caliper make sure that the recessed slots are at 12 and 6 "o"clock..the slots align with one or two bumps on the inside pad. If you are having problems with your calipers rebuilt one are a good option.If only the caliper slide pins are sticking they can be cleaned and lubricated.Pin lubricant sometimes comes with a set of brake pads.Other than that lube may be purchased separately at an automotive supply store.
disc brakes on the rear of a vehicle have a screw out mechanism that attaches to the ebrake . this means that you must turn the caliper piston to recess into the cylinder.
open the bleed screw to make it move eazier.
rear calipailers do nt comprees!!!
they screw in !!!!
take a pair of channel locke annd just screw them in or you can get a special tool from auto zone for free rental!!!!
if there is a cable and spring attached to the caliper then it is the twist back kind. you need a special tool to rotate the piston back and do not force it. it will ruin the caliper. and also some cars one will turn clockwise and one will go counter clock wise i dont think this is the case with your car but if it doesnt want to turn back try changing the direction.
get a nice pair of snap on water pump pliers and a G clamp .place G clamp on piston and apply slight pressure then turn piston with the water pump pliers ,better getting er indoors to tighten clamp very slowly whilst you support the caliper and wind the piston in at the same time.
