Rear piston wont wind in but will wind out????

[Wee Scamp]

Rear piston needs to go in to accomodate the carrier and pads but it just doesnt move in when turned clockwise. But if turned anti clockwise it still moves out.

Whats going on?!?!?

Have you released the cap on the fluid reservoir?

I have now, but it's still not going in. Any other ideas?

Not sure really, maybe try it with the bleed nipple open?

Did/does the opposite caliper wind in ok?

This was the first one I tried so not sure yet, if no luck with the bleed nipple or some "gentle" persuasion will give up and try the other side to see if it works.

Can the piston actually come off its thread? i.e. can u unscrew it too far?

i had troubles with a scenic caliper piston last week, didnt free up until i put a long extension on the wind back tool it were that stuck.

Try winding back with some pressure applied as well. Hopefully you are turning the piston clockwise. I just used a flat piece of metal the fitted the slot.

Used a combination of the advice offered and all seems OK now.... thanks everyone.
