Hi folks,

I'm in the middle of replacing the rear discs and pads on my 2019 1.5 Scala.

I am under the impression that the piston needs to be wound back into the caliper as a post to just pushed in.

I'm winding it back in but it doesn't seem to move. Am I just turning the piston in the caliper or is it just very very slow to retract?

Thoughts.

Cheers

Happened to me on the Golf I owned previously. Turned out to be due to there being a 'load apportioning valve' in the rear hydraulics which shuts off the hydraulic circuit if the wheel is down. If you have the car jacked up then this may be the cause, because the hydraulic fluid is blocked from returning to the master cylinder.

I solved it by attaching a pipe to the bleed valve and opening the valve before winding back.

One other thing - the cylinders on the Golf had a left hand thread. Took me a while to work that out☹️
