[urq] rear brakes (minimal urq content)

[Buchholz, Steven]

... no A4 BTDT, but enough on other Audi rears to say they are probably
similar.  When you say that you had the proper tool, are you saying that you
have the tool that pushes against the opposite side of the caliper housing
so that it compresses the piston as it turns?  I've never had the process
take more than a couple minutes per wheel with that setup.  

The mechanism is intended as a fail safe to provide a means of getting some
braking via the e-brake even when the hydraulic system is not holding
pressure ...
