Two problems related to brake disc pads have been reported for the 2003 GMC C2500. The most recently reported issues are listed below.
My truck only has half of it's braking power. The brake pads are rusted to the slides & have not moved for a very long time the rotors on all 4 wheels are completely engulfed in rust. These are the original brakes. I took the truck to GMC for service [oil change] & they stated the rear rotors were "very rusty". I asked the serviceman what to do & he said either I needed to have the rotors turned or the brakes would wear out prematurely. It is obvious to me now [after looking at the brakes personally] that they were not working or the rotors wouldn't be rusty at all. There was never anything said about the brakes not working or the extreme safety issue of a 3/4 ton truck going down the road with only half of it's braking power. I talked to the bbb and they said when I took the truck in it had 48000 miles on it & was out of warranty. I have no doubt that this situation started before the warranty expired but I was not aware of it. My truck is a 2003 and I take very good care of it [serviced regularly and garage kept] and there is no reason the brakes should have rusted this way unless inferior parts or workmanship is involved. I know two other people with similar trucks and one of them has exactly the same problem as mine. We looked at his after I discovered my problem. He, as I, were unaware of this dangerous problem. I think there are a lot of general motors trucks out there with this same problem that people are unaware of. I believe there should be a recall or at least an independent study on this potentially deadly situation before someone dies if they haven't already. Thank you for your time, dale soverns.
Started feeling less braking power and squealing at 25000 miles on the odometer. Took truck to dealer to check it , found rear brakes to be 100% wore out. Rear rotors are flaking apart.
