I do think Chevy has a durability/quality of materials problem with their light truck braking system.

I know for a fact, that they had a problem with the dually's brakes...
I bought a brand new Silverado Dually in '97...
Only 10,000 miles or so, I had a bad brake vibration. (warped rotors)
Took it to the Chevy dealer, and they just turned the rotors...
I told the Service Mgr this would only make the problem worse, due to the thinner rotors up front...
He said there was no recall or service bulletin on the duallys, but there was a problem with the proportioning valve on the HD suburbans...
Seems the brake bias was too much on the front end...
This caused premature front brake wear, and very little on the rear...
Sure enough, just after my warranty had expired, the rotors were warped again...
Visit to the Chevy dealer again...
This time I was quite firm in my belief that they should have installed NEW rotors the first time I was in with warped rotors...
They agreed, and installed new front rotors, new pads, and special high friction rear shoes under warranty...
I never had another problem with it after that...
And before you say the warped rotors were a result of poor driving habits, I will say that was NOT the case...
The 3/4 ton pickup I traded on the dually had 68,000 miles on it, and still had the factory front brakes...
