The brake pedal travel required before the brakes actuate is very long on my 95 S6. Much like drum brakes needing adjustment. The brakes are normal once this slack is taken up, but I find this long travel disconcerting. What is the travel like on your S6 or A6. I would guess an A6 would be the same as far as the brake travel is concerned. Thanks, Eric 95 S6 84 Olympic
