I noticed many other complaints similar to what I have experienced. Without warning, over a couple of small bumps or area of rough road, all braking is lost. It is a scary feeling especially if there is traffic or a traffic control device in front of you. I did notice that this happens less with weight in the pickup box.

See ODI 755882. I own 2 2001 chev S10 ls 2 wheel drive extended cabs. Both have the same or similar problems. A. the molding along the bottom of the windows on the doors is loose and comes off easily. One of the trucks has already the moldings replaced. The windows sometimes go out of alignment and tilt out. B. the rear end clunks/clanks when shifting into reverse. No solution has been found yet. C. the tailgate on both trucks will not latch completely on the driver's side. One truck has been looked at by the dealer. The dealer said the truck would need to be repaired in a body shop. The frame and body components of the box would need to be straightened in order for the tailgate to latch properly. The repair has not been done on either truck yet. D. the most disturbing problem is the strange behavior of the brakes. Both trucks have experienced loss of braking ability. When applying the brake in a quick stop or emergency situation, the brake pedal is firm yet no braking power is felt and the truck surges forward without slowing. Both trucks have had the rear brakes lock up (the ABS failed to engage). One truck had all the pads and rotors replaced at 500 miles. This corrected the loud rumbling sounds and vibrations from the brakes but did not improve the ABS. The other truck now with 22,000 miles shakes violently at speeds over 40 mph when the brakes are applied. It feels like the wheels are seriously unbalanced or the rotors are badly warped. However, the rotors were checked and found to be in spec and the wheels were balanced. Still the problem continues and is intensifying daily. The shop which checked problem called GM and was told a "pulse" is normal in all vehicles with 4 wheel ABS systems. I drive over 1000 miles a week. I think I know the difference between ABS brakes engaging and wheels about to fly off. I have spoke with several other 2001 GM truck owners at the dealership who are all experiencing problems with their brakes.

I have taken this to the dealer three or 4 times. When they drive it around the parking lot it doesn't do it. The pedal would go to the floor. It doesn't do it all the time. The brakes have gotton better on regular driving now. When you go over a few little bumps that the pedel disappears. I went right through a stop sign after hitting a few bumps. If a another car had been coming I would have hit it. The car stops, but not when it should. My son drove the car and said it did the same for him also. I told them at the dealer to go over some bumps and see what it does, but they did not. This is the dealer frank beck in hillsdale mi. And the dealer royal Chevrolet in coldwater, mi. Both dealers said they couldn't find anything wrong. Didn't put on hoist. I can't believe my truck is the only one with this problem. I am afraid I will have a bad accident, maybe kill someone with this brake problem, or get killed myself. I don't know what else to do about this or who else to go to for help. I will be expecting to hear from some one soon.

When applying ABS brakes vehicle intermittently pulls to right or left, cause unknown. Dealer first replaced brake hoses, however problem occurred again, dealer then filed calipers and aligned front end, this helped some but still did not correct problem, consumer removed ABS fuse and vehicle did not pull when braking anymore, consumer told dealer about this, dealer replaced ABS module and valve, replaced calipers, and problem still exists. Inside mirror replaced, it would not adjust. 3 uniroyal tires were out of round and were replaced, size P205/75R158, tires caused vibration and shaking.
