Brake Light On problems of the 2002 GMC Sierra 1500

While driving in town, I depressed the brake pedal to slow for a stop sign traveling under 25 mph. The pedal pressure felt firm/normal for a brief second and then went nearly to the floor and I was barely able to stop. The brake light on the dash did not illuminate until approximately the 10th time I tried to stop. If there had been someone in front of me or I was traveling in a higher speed zone, I most certainly would not have stopped in time. The diagnosis is the rear brake line rusted through. I've been told by several mechanics that all the brake lines will have to be replaced as they are all so rusted no one line can be replaced without damaging the rest of the lines because of their close proximity to each other. I can't find anyone that will take on the job.

I was at my local coffe shop drive thru. I left the drive thru and as I approched the exit, rolling very slow I expierienced the dreaded gm brake failier. My foot went to the floor. Luckily I was able to use the emergency brake before involountarily merging onto a busy secondary road. I understand rust is inevitable but all of the brake lines are beyond repair according to my mechanic - he will not repair them only replace them. My bigger issue is the fact that since 1967 all cars & light trucks use a dual master cylinder enabling the vehicle to stop incase of brake failier. My GMC and apparently others have the same issue - that even when a line blows the trucks will not stop! the dual master does not do what it is designed to do! this coupled with the fact that I also have been plagued with abs low speed problems since 60k I really feel that gm engineers and bean counters need to agree on safety. Considering that brake lines of thirty years ago are better than late model products would it really be that much for the feds to require stainless steel brake lines? my 2002 sierra looks good but the underside (chassis, suspension parts and brake lines) are not good. This truck is not a good investment and it is definately full of safety issues. If I was in traffic I am sure that I would not been able to stop without an accident. We as consumers do not need third brake lights and useless abs brakes. We need brakes that work when pressure is applied to the pedal!.

I had a complete brake line failure going up toward intersection yellow light tried to stop almost caused crash, no warning the brake light signal went on after it happened. Pulled off into shopping center using emergency brake. Towed to mechanic where I found out the line broke in front of the abs system and all the other lines are just as rusted out and will break if not replaced.

The contact owns a 2002 GMC Sierra 1500. The contact stated the brake light illuminated constantly, the vehicle lost brake fluid prematurely, and a brake line ruptured while driving. The vehicle was taken to the dealer who performed a diagnostic test that located the failure in the brake lines, and calipers due to corrosion. The vehicle was repaired. The dealer replaced the brake lines, and calipers. The failure mileage was 102,000 and the current mileage was 109,963.

On my 2002 GMC Sierra 1500 extended cab 2wd the abs and brake lights go on and off. I had my local gm dealer address this on several occasions they have come to the conclusion that the abs brake module is bad. I asked if there were any recalls on this they said their is a bulletin out that the grounds could be bad so I had them do this fix it did not correct the problem also their was a recall to fix the speed sensors in the wheels which they fixed also did not fix the problem. I decided to google this type of problem to see if other people had this same issue I have found hundred of thousands of people with exact same issue or were it has even gotten worse and the lights stay on all the time. It seems to affect gm vehicles made from 1999 to 2007 cars and trucks but mostly trucks. To me this is a big safety issue most people do not know that when both of those lights are on they have no abs. I was lucky to have a good service manager who explained this to me and how often this problem occurs. Thank you.
