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

When applying ABS brakes pedal becomes extremely soft and nearly goes to floor, causing extended stopping distance. Also, brake pads and rotors have been replaced. But has not corrected the problem.

Repeated problems with brake failure following vehicle being parked in wet weather. Sometimes there is near total loss of braking capability, sometimes severe vehicle "bucking" while trying to stop. Symptoms diminish after several blocks of driving, re-appear after vehicle is parked for a few hours. Dealer examined shortly after we purchased vehicle (used) and found no problem. Have talked to other owners of Suburban and GMC/Chevy light trucks of similar vintage and have found similar complaints. Recent episode involved inability to stop and vehicle continued clear through intersection. I suspect rear brake linings/drums rust and tend to lock/release which seems to confuse the ABS system until linings wear clean again. Vehicle is a hazard to operate for first few blocks in wet weather.

I have been having ongoing problems with the brake system ranging from mild to severe vibration felt on braking. The discs and rotors and drums have been replaced 3 times in under 40000 miles. A number of other trips to the dealership have been unsucessful in correcting the problem.
