Brake caliper piston stuck

[Viking42]

Alright, on my 1990 240SX the driver's rear caliper piston will only move out. The only way to get it to go back in is to screw it in. The other rear one will go in and out. Should I just go and buy new calipers, or is there a way to fix this?

You'll need new seals to fix it. The seal kit for the rear is a bit tricky to work and unless you've a bit of patience, it'll take some time and quite a bit of work with snap ring pliers for the rear.

Your rear calipers should screw back in, if you just push it back in with a clamp you will break something. Get a brake tool, or a pair of needle nose pliers if you're cheap, and screw the thing back in. Remember to either crack the bleeder screw or take the top off the master cylinder when you do it.

The calipers are completely off the car.

So then the passenger's side, which could be manually pushed back in was broken?

they have to be twisted in since the ebrake uses the pads as the ebrake. if it freely slides in without twisting something is broke inside you will most likely have to replace the caliper.
