Units with 4 wheel disk brakes may develop at situation where the park brake does not hold as it should. Our technicians tell us this can be caused by worn park brake shoes located inside the drum section of the rear brake disks. The worn shoes should be replaced and properly adjusted to correct this issue.Google+

GMC Sierra 1500 Parking Brake Does Not Hold Due to Worn Parking Brake Shoes
GMC Sierra 1500 Problem
Average Mileage: 135,679 mi (55,000 mi - 222,037 mi)
not only does the light come on but , the damn thing would make noices like if the shoes were not releasing the disc . i tried a few diferent things to get rid of the noice. even took it in to a shop and had to keep taking it back . the guy said it needed adjusting and adjusting and adjusting . thing is is wanted to charge me EVERYTIME !!!!!!!!
finally , i took the whole damn assembly OFF !!!!! no more scrapping noice .
no parking brake , but who gives a crap . damn thing NEVER worked anyway . not even with new shoes . manufacture design SUCKS !!!!!!!!!
in my opinion , if ur gonna have disc in the rear . why not go with CALIPERS , NOT BRAKE DRUMS AND SHOES ???
