Hi all, my RR caliper was seized on the handbrake and causing problems so I bought a second hand replacement. When I got it the main seal was ripped so the seller (after my suggestion) paid for a big red seal kit. I unscrewed the piston and replaced the seal and the brake works perfectly.
Now the problem is that the handbrake seems to be disengaged from the piston. If I fiddle with the piston position (by turning) then it will "locate" and the handbrake will work, but then after a little while it disengages again.
Any suggetion on how to remedy?
