Ten problems related to brake disc have been reported for the 1999 Chevrolet Silverado. The most recently reported issues are listed below.
The front and rear brakes had to be replaced frequently. . . .
Both rear rotors have heavy corrosion. Inboard disc pads wore to metal. Out board pads have over 1/4" left on them. Emergency brakes have stuck and wore out. 42,000 miles is too early to have this type of problem! it is a safety issue. I had no idea that my rotors were grooved and the brakes worn out. There was no indication. Dearlership will not stand behind the product saying that it is normal wear. Other dealership says it is not. GMC so far has not been helpful.
Brake calipers are deteriorating the metal surface which is building rust, and destroying brake pads. Contacted dealer, and dealer stated caliper and pads had to be replaced.
One right rear brake pad wore away to nothing and was grinding away at the rotor and when I called veronica perez,a g. M. Customer rep. She called ross moody to talk to the service manager and he told her that one brake pad out of eight failed because of rust. I have never before seen one brake pad go bad unless there were something wrong with the brake caliper or asembly but g. M. And the dealership are both saying nothing is wrong but I know there is. I'm retired from g. M. And can't afford to put new brakes and rotors on my vehicle in another 27,000 miles when my warranty expires and this problem happens again.
Front pads have never required replacement as of 102000 miles. There appears to be a very serious design flaw with the rear caliper braking system. Cause possible loss of braking and serious accident or fatalities.
While coming to a stop sign brakes would squeak.
On 10-1-99 I complained to my selling dealer about a metallic noise coming from the right side of my vehicle when I would go over a bump or back out of my driveway. I've complained numerous times since then and each time the dealer says that they can't find or duplicate the noise or they blame it on one of my aftermarket accessories. The last time I took it in on 10/16/00 the dealer told me that it was my aftermarket exhaust system making the noise. I didn't install the exhaust until 7/00 and I've complained well before this time about this noise. Well today I got under my truck to investigate for myself what could be the source of this aweful noise and that's when I discovered that both of my rear brake caliper assemblies were loose. I was able to wiggle both of them with my hand but the right rear was the loosest. At this point I decided not to touch them anymore, I considered tightening them myself but decided against that just in case anybody should wish to inspect them. I immediately went down to my selling dealer and spoke with a manager but of course they told me to bring it back in on Monday, 10/30/00 instead of immediately repairing the defect that I've complained about so many times. This is definately a safety hazzard and one can only immagine what would happen if the bolts came all the way out completely and the brakes were applied. I would like to see these trucks recalled and the brake bolt torque checked to insure that it doesn't happen to anybody else.
Since new, brake performance has been erratic in normal driving situations, varying from fair to very poor. Pedal is spongy and requires excessive travel. Pedal falls whehn stopped a lights. In normal stopping, one must keep pushing harder and harder on the pedal to maintain a constant rate of speed decrease. Ordinary stops become panic stops because braking action is not predictable. Anti-lock feature engages with slight bumps and at slow speeds, lengthening stopping distances unexpectedly.
No summary listed for above vehicle.
Rear disc brakes and rotors needed to be replaced at 20,000 miles due to poor design.
