Re: S6 Brakes, Please Help

[rjandrew@post.cis.smu.edu (R Justin Andrews)]

Tyr draining all old fluid out of reservoir, refill and flush all
brakes with fresh fluid! Does wonders for brake pedal feel!!
We used to do this regularly and I was the one who worked the pedal
at the shop I worked at... I must say every car had a noticable improvement!
very noticable!!! From 911's to BMW 5 series to our beloved Audi's
I did this on my 4kq and the pedal went from blah.. to BLAM.. stops great now!

HTH!
