New rotors at 19,600 miles???!!!!

[Gbuzz71]

My 03' Silverado just failed inspection due to the brake rotors being corroded and rusted. I can't believe it!! Has anyone had a similar problem with this?? Is there anything I can do, or do I have to eat it.

My rotors were replaced at 35k and about 65k. I replaced them this last time with Brembo slotted rotors. They are alot cheaper then factory and so far they have been fine after about 10k.

Fronts or rears? I don't believe it either myself (not at 19.6K unless you've got some defective rotors) All rotors look rusty as hell if you let them sit without driving them for a bit. It wears off in a few miles. If they're talking about the cooling fins in the middle of the rotor itself, it'll always be rusty and corroded. Personally, unless they measured them and they're too thin for tolerance or warped too badly to use, I'd call BS.

Ya GMs truck rotors have problems like that.We replaced the rotors on our old 2002 2500HD at 20,000 and we replaced the rotors on our old 97 1500 Z71 at 100,000 and 150,000

I agree with the Parrot, either they are wore or warped, else okay. Unless your driving around with one foot on the brake and one on the gas or towing major loads there is no way the can be wore out.

He showed me the driver front rotor. And the inside part if the rotor was about 80% rust. He said I'm breaking on rust. The other 3 weren't as bad, but they were on there way to looking like the front driver one. I've been checking online and it seems GM has some sort of problem. The guy also said that the pads are harder than the rotor, cause they used a recycled metal to make the rotor.

the pads arent harder than the rotor, theyre at most semi-metallic. as for the rust a picture would probably be the only way to tell you yes or no for sure. as for it failing inspection, in missouri we cant fail rotors unless theyre cracked or under spec.

[swingline]

what usually happens on the silverados is that the rr calipers get all the road stuff(dirt, mud, ect.) thrown on them(my theory is they should be mounted towards the rear of the rotor like on the front, or vise versa, i'm tired) for some reason and stick so it's like riding your brake lightly all the time.

i have worked on numerous trucks with this problem and the right rear was always the worst. i'm going to call bs too because he showed you the front drivers pad.

By the sounds of it the guys a freaking idiot

Just a quick FYI..Gbuzz..my dealer notice that I was gettin a noise and vibration from rotors and said they found them to be CORRODED!! So they warranted new rotors, pads, and calipers for the rear of my 03 ext cab. You are not alone.

The rears in mine were ground out at 20000KM back in 2003. I attributed it to the ceramic pads, I replaced with regular semi-metallic pads and aftertermarket rotors and no problems since. Apparently brakes are not a warrantable item.

The mileage seems low but I had the rotors on my Subaru(15% GM owned at the time) start to "delaminate" from rust. If you live where they salt the roads a lot it eats the vented rotors from the inside out.

Well I had to replace the rear rotors,pads and calipers.

I've seen this a couple times. The rotor actually fatigues and the metal surface erodes or disintegrates and leaves a recessed rough surface that looks like rust, but it's deteriorated metal due to heat and fatigue. Real mess. If this is actually what you have by all means replace them.
