Re: Rear proportioning valve QUESTIONS

Fellow Audi fanatic,
    another thing that you might want to check is that the sliders for the
calipers are free and not siezed.  If they are then remove the caliper, take
out the sliders remove the rust with steel brush or steel brush wheel apply
high temp brake grease and put caliper back.  About 4 months ago I did a
complete rear brake job rotors, calipers, pads, still need cablesand I
noticed that the sliders on the old calipers were rusted solid, had to use a
torch to remove them.
