The piston could become skewed since they went too far out. Try moving the handbrake arm if its at the end point, then center the piston. Else push out the piston and refit it with new seals.Guys,
Hoping for some ideas/knowhow/intel on rear brake caliper pistons in my 2001 156. I'm half way through doing a brake overhaul - new discs and pads all round.
Fronts are done and were straightforward - but I'm getting nowhere trying to retract the rear caliper pistons. I've got a wind back tool - but can't get either piston to move at all....?
They seem to be seized - feels unlikely that both would seize - unless I'm missing something....? The brakes have been neglected before I got the car - the pads worn well down to the metal - and the discs totally destroyed.
Can anyone please shed any light - make suggestions? Thank you.
Regards

Just there to stop dirt getting it, you can ease the rubber away from the top of the piston and squirt (for example) plusgas into the caliper.Is the rubber sleeve just there to stop dirt or is it a fluid seal too?
Can't help you with that one, never taken one apart. If you got a one where the rubber is damaged you're not going to lose anything by being heavy-handed with it, rip it off, may find it just sits on/under a lip or held in with some sort of clip.How do you actually get the old sleeve off and securely fit a new one?
