Noisy brakes --WTF?

[David R.Birch]

Today I dropped off my '07 Subaru Outback Sport SE at the dealer
because the rear brakes were making a grinding noise when I braked.
28000 miles on the odometer, 23 months since I bought it new.

The dealer replaced rear pads and rotors under warranty, said they
were all shot.

I am not a hotdogger, if I were, I'd have a WRX.

What can destroy rear brakes so fast?

Driving with 2 feet (one on gas pedal, other on brake) instead of using
2 foot for both pedals (to ensure you're either gassing or braking but
not both at the same time). Another cause of brake drag could be a
partially engaged parking brake, or a poorly calibrated one.

Did they inspect the calipers to ensure the slider pins were clean and
lubricated?

If both rear brakes where bad, I'd suspect a bad proportioning valve.
Not very likely. More likely just one side was bad. Normal practice
to replace both sides when only one side has a problem. Likely one of
the pads had a manufacture defect: too soft or too hard. Your
driving style not the cause here because the front brakes do the
majority of the stopping. Fronts would have worn out first if the way
you drive was a factor.

Not E-brake since that uses the 'hat' and it's own 'shoes'.

Has to be some kinda manufacturing/parts problem. I've heard of
hydraulic hoses that have 'flaps' inside that act like check valves -
or just some pad installation or defect as others have said. I also
wonder if the ABS could be an issue?

What is this car using for an emergency brake?
My old car uses the front brakes and that could cause your problem if they
are using the backs now.

There is a seperate small set of shoes that operate the parking brake
on 'most' subarus. You can seea little of that detail about halfway
down here;
