Rear caliper piston won't retract

Working on rear brakes today.

Replaced passenger side rotor and pads with a bit of a fight with caliper pins and carrier bolts. Found inserting pads surprisingly difficult BTW, any ideas why?

Was able to retract caliper piston by hand just by using an open ended spanner (19mm) in the notches.


Moving to driver's side, had an almighty fight to get caliper pins out, eventually won.

However, I was unable to retract the piston - would not rotate at all.
Got wife to pull hand brake (e-brake) - cable moved spring assembly, but the piston DID NOT MOVE.
Pressed foot brake, piston moves out.

Is the caliper shot?
 
My guess would be yes. I'd replace both rears. And you need to open the bleeder when you try to push the piston back in. Oh, and the piston screws in, not just push.

Thanks Gerry.

Calipers are hideously expensive! :(

Getting a rewind tool tomorrow, give it another go.

Would you expect to see the piston move when the hand brake is applied?
I would have assumed so...
 
You would. You may have some corrosion and seal issues that may necessitate replacement. You can usually grab some decent rebuilt calipers from a parts store for less than a hundred.
