Why is my truck making this sound?
** When I back up / pull forward and hit the brakes my truck brakes grind. I
can feel it in my pedal and my brakes do not function to their full expectancy.
My dash DOES NOT have a light ... however, I do get an e-mail from OnStar
stating that my ABS system has an issue and needs repair within 7 days. I
took my truck to GMC and they stated 'nothing is wrong with it' ; they ran a
scanner and it put out no codes. I continue to get the e-mails ... also my
brake pads are in good shape .... HELP!
