Brakes and other issues.

Q&A:

First I'm going to ask - IS there anything special to the ABS system of the
99 A6 avant?

Would it be bled in the tranditional way if I used a "power bleeder"?
I'm specifically looking for, if there is some special bias porportioning
valve that would
need attention, or some other gimmick beyond:
Don't flush backwards and clog the ABS control unit.....

Why I ask:
I guess its going to boil down to the basics. - again.
The car's Audi assured ~9 months old to us, bought around 38K Guessing.
I'd sware my eye said half the pad was there when we bought it.
Sandpaper sound from the back pass brakes after simple service -If I knew
I'd tell ya, 45K?-

Now roughly a month later the pass rear is making all kinds of bad metal on
metal
sandpaper sound.  At any speed.  Car now has 50,200 miles.

So I take the first Clue:
Excessive copper brake dust on that alloy wheel only, and peer
at the caliper holder, rotor and the outer visible brake pad:
Scored like you'd make an extreme example out to be.
Deep gouges and worn metal on the outer brake caliper assembly.

My guess is the piston boot is either torn and the piston froze, or
something is not letting the piston retract from the brake pedal build up of
fluid pressure.

So it seems that the brake has "dragged" for some time and the repair could
be more than pads and rotors.

QUESTION 1:
Since brake pads and rotors (and fluid flushes Says Audi of Nashua) are not
warranty items,
do I have any leverage in claiming that the rear pads should have a
signifcantly longer life span than 50K?

Since the rears are 30% (15% - a side) of the braking force, won't the
fronts pads have gone first?
( i know the answer, but I'm thinking out loud)
Even if the fronts were replaced when we bought it, why is one rear
significantly worse that the other?
(haven't eyed the drivers rear but there's no dust on the alloy wheel fronts
or drivers rear.)
This leads me to believe that the Mrs. DIDN'T drive around with the e-brake
on.
Especially with the other side fine.

Question 2:
Is there something done in the 45K service that would affect the rear brakes
or is the caliper a
previously damaged unit prior to or our taking delivery of the car and
therefore be part of the caliper
malfunction and be a warranty issue or goodwill item?

Am I dreaming, or should I buy the pads, rotor and caliper and do the repair
and bleed myself?
