should I go head with what dealer suggests regarding rear brake?
dealer says "the vehicle needs rear brakes. They measure 3mm the estimate is $816.98+tax"
the brake pad warning lights have not come off yet.
the car is at 30k miles. I have no ideas if this is common wear on the brakes? please help. Thanks!
another million dollar question: can I drive this car safely for an extra 3k miles?
I am about to move cross country next week. If not that urgent I'll change them at my destination, and use a good indy shop if I can.

30k is not unheard of for needing brakes on a beast as heavy as an A6.
OE rear pads are $100 a set (aftermarket can be cheaper maybe $60)
OE rear rotors at $260 a pair (aftermarket could be down to like $80)
I'm sure dealer list price is more...
So they are charging roughly $400 in labor. I'm not sure what the labor rate is at your dealer but $150/hr is possible, so roughly 2.5 hours. Sounds about right. Might want to get a quote from a good indy shop.

If it were me, I would get them done before going cross country. If they fail on the way that would be a challenge if in the middle of nowhere not to mention any safety considerations. I also assume the car will be loaded down with stiff since youre moving which will add to the gross weight of the vehilcle and stopping effort.
A bit surprising the rears need to be replaced but not the fronts - front brakes usually wear out sooner.

The ABS/ESP module has a hydraulic pump to push brake fluid down the lines and activate the regular service brakes. The cruise control can utilize this mechanism to control the regular brakes as well.

I wouldn't think that the parking brake would be used by the ACC.
As to front brakes usually wearing sooner, it's a reult of the front weight bias as the car's mass is transferred forward even though the rear brakes are equally applied.

From an engineering standpoint... It seems logical that the ACC uses the rear paring brake motors to slow the car down. There's no motor in front obviously. So us ACC users get higher brake wear on rear. Since the ACC is more conservative I do notice it hits the brake more often than if I just let off the gas to cruise to a stop without the ACC.
So Yes I believe the ACC wears the rear brakes sooner. I'm second owner of my Audi but my rear brakes were first to wear to levels needing replacement while front brakes still had half-life still left. Just my 2-cents.

Just put rear brakes, pads & rotors, in my wife's 2011 Infiniti G37XS at 60,000 miles in July. Fronts were still plenty good. When I questioned my mechanic as to why I was replacing rears before fronts he stated this is very common in late model vehicles with ABS, traction and stability control as those systems utilize the rear brakes at times to make adjustments when these safety systems intervene.
