Brake Disc Caliper Problems of GMC Suburban

I have owned the sub for about 5 years now. First off I really enjoy driving it. I need to say my vehicle is modified and not stock. 9 inch lift 38in super swampers, and a couple of engine upgrades. I can verify however even before I installed the lift and tires I had a couple of problems. #1 always had uneven wear in the front brakes, 1 caliper (front) would always burn up the brakes faster. I made sure I used gm pads from the dealer. I also made sure the calipers were moving freely and guide bolts lubed with gm supplied grease. #2 poor braking performance even with vehicle unloaded, I guess I figured this one out by myself. Not to be rude but why would gm equip a vehicle with a automatic transmission that is rated at approx 7,300lbs with a tiny braking system. In my opinion small pads+small rotors=long stopping distance. #3 detonation, going up small inclines 1/4-1/2 engine throttle. This has always happened. Even though this may not be gm's problem I just wanted to get my 2 cents in. I understand all gasoline is not created equal, I have to use 92-93 octane with a fuel additive to get rid of the noise. Is this not a fuction of the knock sensor? I maybe wrong but shouldn't the knock sensor back off igntion timing via the ecu when detonation is present. #4 door hinges loud/noisy breaking.

We have reported excessive brake wear and pulling to the manufacturer. When brakes are applied, vehicle pulls sharply to left lane. Dealer has replaced pads and rotors and calipers six times in 10,000 miles. Other owners are experiencing same problems. Manufacturer rep says to just pull harder on steering wheel. We have also contacted better business bureau for buyback. Gm service managers tell us this is manufacturing problem and cannot be corrected.

Whenever t abs brakes wer applied, vehicle would be pulling to the right. Had taken vehicle to dealer & the mechanic swapped the rotors & the tires. Also the right front calipers were swapped.

Truck pulls when braking. Tbs fix implemented with little to no improvement. Last time at dealer, dealer said GMC has problem with 3/4ton Suburban brakes but doesn't have fix. Nothing he can do. Truck has had combination valve replaced, rear shoes replaced, front pads replaced (5x total), calipers replaced, rotors replaced, tie rods replaced, idle arm replaced, steering box and pitman arm replaced, front brake hoses replaced, control arm bushings replaced, and aligned several times with no fix to the problem. Braking at highway speeds it is very dangerous. You don't know which way the vehicle will go and how hard it will try to get there. As an engine designer I find it amazing that gm has a handling/safety issue of this magnitude. This is a big truck to have such a controlability problem. Please help. A shaull.

While driving applied abs brakes, started pulling right when heated; pulls left when cold; passenger's side brakes wearing faster than driver's:took to dealer; cannot find problem; did change pads/calipers & had passenger wheels rotated.

Vehicle will intermittently pull to the right and also at intervals to the left, cause unknown. Dealer is in the process of replacing the brake calipers, but found no remedy for the problem. Please give any further details.

Suburban purchased and driven without trouble until 4-99. Taken to ray skillman dealership with notation that the vehicle pulls right when braking. Dealer replaced both front rotors and both front brake pads. Car initially improved but with progressive return of problem. Taken to bill estes dealership, 4105 west 96th street, indianapolis, indiana, 46268 (phone 317-872-3315) the next five times for repair of problem. On 6 oct 2000, with 50,299 miles (still under extended factory waranty), the estes shop documented the brake problem. The car would, and still does, change lanes to the right--one lane in 3 seconds at mild to moderate braking at 50 mph. Estes r&r both front caliper assemblies, brake fluid, caliper assemblies, and hoses. Didn't work. Taken back to estes on 27 October 2000. Problem again documented.
