yes dealer only they cost around 75.00-100.00

 

The advise above is correct
The pad wear is from a sticking caliper or slides
I would remove the caliper
take the slides apart - clean them real well and lube
and bleed that caliper
See if that makes a difference - if no - then it will need a caliper

 

what lube would i use?

<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1336875&evc=numSrch#ss1-1336875">Condition

Some customers and dealers may comment on accelerated rear brake wear on some of the above listed vehicles. This condition occurs mainly on the right rear inboard brake pads and on vehicles that are exposed to extensive off-paved roads.

<A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1336875&evc=numSrch#ss2-1336875">Correction

Install a mud flap forward of each rear wheel using the following procedure. Installation of these mud flaps and following the recommended off-road driving information provided in the vehicle's Owner's Manual should greatly reduce the possibility of accelerated rear brake component wear.



Important

Always work from outboard to inboard, drilling one hole at a time and securing with a fastener. Follow the sequence of the procedure. This will prevent distortion of the mud flap.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer".

Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
