Re: ur-Q brake woes.....?

  Hi Chris!

  You pretty much got it right. The brake warning light does light,
  sometimes, when pumping the brakes with the engine running.
  It's weird. It seems like two failure modes at the same time,
  accumulator and master cylinder.....

  I think the hydraulic boost system is OK, the PS works fine, but
  no brake assist immediately after engine shut-down indicates
  a bad accumulator. The way the pedal goes to the floor
  indicates a bad master cyl.

  What's a Audiphreak to do?
