[urq] rear brakes (minimal urq content)

[James Howard]

My rears on the A4 are very similar to the urq.
The tool should push the cylinder in as it turns it,. It does more pushing
than turning really. Sounds like you've been doing a LOT more turning than
pushing. The same proceedure is used for the urq rears.
The real PITA with the A4 rears is that there is no hub. There is a stub
axle and the disc itself contains the wheel bearing. If you want to change
the rear discs, you have to press out the bearing and press it into the new
disc...

Jim.
