i have a 04 and with about 38k on it i had the rear caliper off to do a new stud and noticed only on the passenger side my brakes are wearing...

Inside pad on the single caliper setup was almost gone and outside was fine, so the piston looks like it was sticking, I bleed the brakes and re greased everything so ill see how it does, but i was wondering if this was common...

 

Sounds like my '99. It does the same thing, and continues to do it.

 

my 99 does the same , sometimes when going around corners i can hear it rubbing! havent figured out a way to fix it yet

 

Same as mine, but on the driver's side.

 

wierd..

 

There's an old TSB in reference to pre-mature rear brake pad wear, not sure if it applies to your year. It basically says that the rear brakes may wear pre-maturely due to crud, moisture, etc. splashing on the rear brake assemblies, creating rust, frozen sliders, etc. The fix is to install some rubber flaps in the fronts of the wheel well (where the front 2 support rods for the rear quarter are)

 

I know my original rotors flaked off. By the time the rear pads were 3/4 worn I had two thin bands of wear on the rear rotors approximately 3/8 inch wide. I had to buy two new rotors. Unfortunately for me they were $100 each since I have a SS and the rotors are larger. Also the rear calipers are two piston.

almost every truck does it with disk brakes..and the way gm fixed it was with going to drum brakes..

 

i had the same problem on my 99 i replaced everything with united parts and ceramic pads

no more problems 30k later
