So i go to change my rear pads and rotors...so i take the caliper off and the piston wont go in...so does that mean that my caliper is seized?

 

You did try to turn the piston in right, not pushing with a clamp? My teg has pretty stiff rear pistons, but they do twist in so the pads will fit.

My friends teg however has rear pistons that won't screw in for nothing, even with a tool that fits the "X" in the piston, still won't budge. He is stubborn and has been using an old set of pads where the piston doesn't have to be pushed in so far to mount them. Eventually, I believe the caliper must be rebuilt or replaced. Rebuilt calipers are around $70 from local parts store chains after core return.

 

it was my boy doin thing so i guess he didnt turn it...i told him u have to turn it...it is a nissan guy...thx
