Rear disc brake
I wonder if anyone had a similar problem?
I replaced the rear discs and pads.
Everything went well.
On driving there is a rubbing sound from the rear right.
I thought the pads were duff so stripped it down and greased everything again and all was sweet.
Pushed the piston in and slipped the calliper over the new pads.
pumped the brakes etc and took it for a drive.
The rhythmic rotational rub at one point is back again same side.
Any ideas please?

Re: Rear disc brake
Sounds like you have a high point on the pad sides or surface that it touching, if you are getting a rotational rhythmic sound. Check out the pads and metal holders of pads, for scoring.
Solution: File down offending protruding area, or just change the pads for new ones (another make).
Also are your calipers releasing after braking, or just slow releasing? Reason: Jambing up?, check on hill you are free wheeling after braking.
The usual noise on pads are screeching when braking, and that is due to the leading edge of the pads, solution: need filing at leading edge to give a more angled shape across the leading edge.
Thats all I can come up with at the moment, Cheers.

Hi Jim
Many thanks for your reply and help.
The car moves easily with the brakes off on the drive as a slight slope with engine off.
This has happened after fitting new rear discs and pads.
I also thought the pads were duff so took all apart cleaned again and fitted another set of pads.
I did notice that I had to be quick fitting the calliper over the pads as it kept moving out even with the cap off the brake fluid reservoir.
I am now thinking a faulty calliper. Or maybe I need to clock the run out of the new disc with a TDI.
Your views appreciated.
A Calliper is not expensive.
