I removed all everything out of my way while changing my pads and rotors, I used a caliper rewind tool to push the pistion back in and it went in fine... but I had to call it quits because it got too dark to see so I firgued I would finish up tomorrow ie as in today........

so today i go out and i noticed the piston came back out on its own and wasn't not pushed in anymore after I done gone and had it in the bore yesturday.... so i'm like ok whatever i get the caliper rewind tool out again but this time the piston will not budge! I can sometimes budge it an inch or so but thats all.

whats my problem or what happen to it over night?

by the way this is an 88 non turbo 4 lug and its the rear left side on car caliper

 

please bumpy

 

does anyone know what may of what happen to my capiler piston???

please i need some thoughts and answers.

 

did you rewind the caliper while it was still ON the car,and hooked up to the Brake system?

 

hmm yeah i unbolt the wheel, unbolt the caliper bolts, knocked out the old pads, then took the re-wind tool and tried turning the piston back in but it wont budge but the like i said eariler that night it did go all the way in, but next day when i went to finish up the car the piston was back out and doesn't wanna even budge now.
