Parking Brake Cable Adjust

Just FYI Bernie, audi/Girling agrees with Phil here.  If you get *new*
girling 36 or 38 rear from audi or aftermarket, the spring is larger/stiffer
than what came on the car originally, or what rebuilders don't replace (they
sure paint it nice tho).

I personally think rebuilding rears is a complete waste of good Nascar TV
time.  When watching DE2, better and more rewarding time is spent doing R&R
on seat heater pads.  Spend a couple hours (or have your mechanic spend a
couple hours) on a rear rebuild, someone will be back there sooner than
later.  Average 6-12 months max here in Chitown.  The problems aren't just
crud Bernie, the ratcheting  arm/piston mechanism wears/sticks.

Your teardown procedure may make sense for the DIYer with good seat heaters,
but if having a shop do it, you are better off working hard on getting better
pricing on the new in box calipers.  Minimally, DIYers should be finding a
good source for stiffer springs.
