Re: S6 Brakes, Please Help

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!
