I was driving in medium traffic when a vehicle in front of me stopped quickly and i applied my brakes. then i noticed the peddle go down to the floor. that was the only warning i received and so i immediately drove home pumping my brakes when i needed to stop and tried to stop infrequently as possible. *tr

My 2000 gmc sierra's frame is extremely rusted. parts of the frame have rusted completely through. all the brakes lines have been replaced due to rust as have many other brake parts. i purchased the truck used but previous owner stated he replaced the brake lines due to a low speed accident. *tr

Thank goodness no one was hurt, and no vehicle hit when my brake lines burst on this vehicle. when repaired the mechanic said they basically rotted off from rust and that this is a very common problem on these vehicles. i understand some maintenance is normal on any truck, but being able to use your fingers to crumble parts of the brake line is not. you need to investigate this before people are hurt or killed, if some haven't been already. you also need to revisit the abs sensor problem from the previous recall. that fix did not work, so all i could do is disconnect them or chance an accident!!!!!!!!!! *tr

Truck had failed to stop at an intersection as we approached red light. upon depressing the pedal the brake pedal went to the floor just enough to get truck slowed before emergency pedal was depressed to come to a complete stop. we were traveling about 20 miles an hour before we reached intersection about 75 yards away. as light turned green, we slowly pulled into a parking lot and parked truck until a tow truck could get vehicle back to the garage for repairs. upon inspection by our mechanic, it was found that the brake line had ruptured near the anti-lock brake housing which was caused by corrossion and poor brake line tubing material. it was noted that material was not stainless steel or any non-corrosive material supplied and installed by the oem. it took two weeks for our truck to be repaired as the mechanic had to customer bend the new brake lines because oem does not have replacement lines which came to a final cost of close to $1300. *tt

Have to replace all brake lines 2000 gmc sierra 4 x4 extended cab. 53,000 mi. i have blown out brake lines 4 times over last three years. all lines to anti lock valve rusted through, front brake ,drivers side,rear line drivers side. *tr

The original flexible brake hose on the front passenger side of my 2000 gmc sierra vehicle failed resulting in the loss of front brakes. it appears that the hose is too long and the hose rubbed on the rim. the delco replacement that i purchased has been totally redesigned. it is much shorter and the connection to the caliper has to be angled at a 45 degree angle, so that the will be no contact with the rim. after replacing the passenger side, i checked the driver's side hose and found the same problem. the hose shows rubbing is occurring. i will have to put a replacement hose on that side also. *ln

Tl*the contact owns a 2000 gmc sierra 1500 4x4. while driving approximately 5 mph he engaged the brakes and the vehicle did not stop. he applied pressure to the brakes in order to stop the vehicle. several vehicles were blowing their horns in order to avoid a crash because the vehicle stopped in an intersection. the vehicle was taken to the dealer who confirmed that the wheel speed sensor needed to be replaced or cleaned and was the cause of the failure. the contact will be responsible for the repair cost. the contact called the manufacturer and referenced recall 05v379000, service brakes, hydraulic:anti lock and was advised that the recall repair had already been performed on the vehicle. the vehicle was not repaired. the failure mileage was 73,100 and the current mileage was 73,330.

While driving home i pushed the brake pedal and experienced a ruptured brake line under the drivers side door. luckily no crash occurred because i was on a back road with no traffic. after inspection it was confirmed that all brake lines were very badly corroded and all were ready to fail. the worst damage appeared near the wheels which i would assume is due to road salt and moisture. *tr

I have a 2000 gmc sierra that had brake line rust through causing brake failure. i got under the vehicle to try and change the line and found all the lines are severely rusted as is the fuel lines. yes my truck is old and i live in the rust belt of n.y but something needs to be done either n.y stop using salt or the vehicles need to be built with lines that don't rust out. this issue i think is a safety issue that would be easily fixed by either no more salt or better line in the vehicles that don't rust through. *tr
