Three problems related to brake master cylinder have been reported for the 2002 Chevrolet Silverado. The most recently reported issues are listed below.
While waiting in line at hardees drive thru,the brake pedal went all the wall to the floor. Upon inspecting the truck I found all of the brake lines underneath had rusted and one from the master cylinder had rusted all the way thru. I replaced this line with a carbon coated steel that cost only $8. 99. However I do feel pretty fortunate because we were headed upon a mountain going deer hunting. I really don't want to think about what could have happened if we were comin off "high knob" and this line had blown. I also think gm is very lucky that someone hasn't gotten seriousy hurt or killed yet but I think it is only a matter of time unless they recall these vehicles and replace all the brake lines with a better grade of steel or a coated steel to protect them from corrosion. Also I read some of gm response to this issue and I would like to reply to them that once a line is blown being front or back the pedal goes to the floor and once the fluid is gone you have nothing but the park brake, if you can actually think about it during all the panic of pumpin the brake pedal trying to get a vehicle to stop. This really is a dangerous problem and these vehicles need to be recalled and all the brake lines replaced.
Started truck, brake pedal went to floor. Brake fluid under truck. Brake lines rotted out under drivers door between master cylinder and abs box. Had to use parking brake to stop vehicle. Luckily my children were not playing in the driveway, or that I was not on the highway. Huge safety issue, and from hundreds of complaints on internet this is a design flaw, not a fluke, or environmental issue. I had inspected at dealer a year ago and they said lines were fine. This was after spending $2000 to replace other rusted brake components. Brakes had been replaced at 20,000 miles also. Truck has been used on highway miles mostly, and has never plowed, or towed, or been used near water.
Consumer stated that he was having a hard time getting the vehicle to stop when applying the brakes. He had to push down hard on the brake pedal to get the vehicle to slow down, then stop. The consumer took the vehicle back to dealer 3 times. Once dealer replaced the brake master cylinder. However, he was still having problems getting vehicle to slow down and stop. The consumer is concerned about the safety issues and feels that the vehicle should be looked at again.
