you take a pair of plyers or a caliper kit from autozone and turn in the calipers. You have to turn them clockwise to make them go back in.
do not try and compress them in, you will damage them.
the piston needs to be turned counter clock wise while compressing the piston
Remove engine, disassemble, replace piston, re-assemble engine and install. Good times!
did you try turning it backwards or left handed. I had a Nissan Maxima and the pistons were left handed
The best thing you can do is replace the caliper.
Use a large C- clamp to depress the piston enough to remove the caliper.
screw it in turn the piston clockwise and screw it in , only for rear brakes
toolsfront or rear?drum or disc?need more infoif front disc then you will need caliper piston compressor or big C clampneed socket for caliper bolts removal
Worn seal. Replace the caliber and bleed the brakes.
If it's stuck that bad replace it with a new or rebuilt one.
If the brakes are disk on the rear they can't be push or pressed in they have to be screwed in by turning the piston clock wise try this it should work. That is what I did on my 1994 Nissan Maxima becareful not to damage the rubber dust boot on the piston.
If the brakes are disc brakes then try opening the bleed screws on the calipers and see if the pressure releases if not then remove the calipers and replace because the piston is probably frozen or you can try pushing in the piston with a c-clamp,if that doesnt work replace the calipers as noted. If the brakes are drum brakes then check your brake cylinders to see if they are leaking if so you can usually rebuild them if not then replace them and bleed your brake system to get brakes back to normal, you can also make sure your drum brakes are adjusted correctly.
If there are disc brake, it could be frozen caliper slides or a frozen caliper piston. If they are drum brakes, it could be a frozen wheel cylinder.
