Caliper Piston Stuck

[Pal318is]

I'm in the process of changing brake pads and have done the front drivers side, no probs. However the passenger side piston won't push back in.
Any ideas on how to do this please?

Thanks

use a G-clamp and the old pad to push the piston back in

Typical, I can't find my g clamp

Is there anything else i can do?

Water pump pliers maybe.

Be sure to put equal pressure around the piston when squeezing back in so it goes back in straight.

I had this problem recently, and used Mole Grips to squeeze the piston back in - best to work it fully in and out a few times.

Think I'm going to need a new caliper at some point tbh. As the rubber, has come away too. I don't have a set of mole grips big enough to push it back unfortunately

Undo the bleed nipple, usually helps.

The bleed nipple is a fooked unfortunately and I can't undo it. Tried that already

Try using a crowbar to lever it back in, and siezed brake nipples can be carefully drilled out, but try using Plus Gas penetrating fluid left to soak overnight first.

I've managed to do it however I think I still need a new caliper..

Thanks for all the help and replies

Bit late now, but two socket set ratchets either side of the piston levering the piston against the caliper. Works every time. There is some advice that you shouldn't always do this without the nipple open otherwise you push crap back into the system.
