Tl* the contact owns a 2003 chevrolet silverado 1500. while driving at various speeds, the brakes failed to stop the vehicle. the contact had to apply the emergency brake to bring the vehicle to a stop. the vehicle was taken to an independent mechanic where it was diagnosed that the rear brake line was corroded and needed to be replaced. the vehicle was repaired. the manufacturer was notified of the failure. the failure mileage was approximately 41,000. updated 09/27/16*lj **updated 01/04/17*lj the consumer stated the brake line rusted to the point where it ruptured. updated 01/05/17. *jb

2003 chevrolet silverado. consumer writes in regards to vehicle brake failure. *smd the consumer stated the brake failure happened with no warning. there were no signs of leak and no other visible or physical evidence of a brake system problem. the vehicle was take to a repair facility. the consumer was informed the brake line system needed to be replaced due to corrosion. *jb

While looking at my truck after getting it back from the shop getting all 4 of the brake lines replaced, i noticed the fuel lines are leaking and extremely corroded. i have always been a chevy lover, and this is my first nice vehicle i have ever owned. bought used in september of 2014. so far we have noticed that just about every recall from the past was never fixed on our truck, so we had to shell out almost $900 to replace the brake lines front to back. now the fuel lines, the windshield seems loose, these are all recalls from the past. it doesn't make sense to put a time frame on recalls considering some people may never find out til it's too late, and others may not find out til someone gets hurt. *tr

Tl* the contact owns a 2003 chevrolet silverado 1500. the contact stated that while driving at low speeds, the brake pedal sank into the floorboard. after inspecting the vehicle, the contact noticed that the driver side rear brake line corroded and leaked brake fluid. the failure occurred twice before. the vehicle was repaired. the manufacturer was not made aware of the failure. the failure and current mileage was 27,000.

My 2003 chevrolet silverado has now had two brake line failures (one in 2010 and one in 2013) resulting in no braking ability. in both cases the emergency brake was quickly used to avoid a possible accident. both incidents occurred while driving within city driving conditions. both brake line failure were due to corrosion according to the auto repair shop. i have also had to replace a brake caliper and a front wheel hub assembly (due to abs sensor failure).

Noticed that brakes were "spongy" the night before. in the morning i started the car, and started to drive out the driveway when i applied the brakes , the pedal went to the floor. the dash board information center indicated "service brakes". i got out and lifted the hood to detect the issue. i saw fluid leaking from a rusted brake line. upon closer inspection i noted that it ruptured. the real issue is that this could have happened while in traffic or when exiting my driveway which is 100 feet elevation from the road. either way it could have been a very dangerous situation. after this happened i researched similar incidences with the silverado. this seems to be a design default that should have a safety recall. i have owned many vehicles, some years older than this 2003 and this is the first time a brake line ruptured. *jb

2003 chevrolet silverado 1500. consumer writes in regards to hydraulic brake line failure. *smd the consumer stated the hydraulic brake lines, failed twice on the vehicle. the last bill was $1200 for the hydraulic brake lines and $600 for the emergency brake.

Truck experienced catastrophic brake failure when a corroded right front brake line ruptured during an attempted hard stop at a traffic light. the brake pedal went straight to the floor and the truck continued through the intersection. pumping the brake pedal had no effect. shifting the transmission down and applying the emergency brake eventually stopped the truck. fluid leaking from the rupture drained the master cylinder reservoir within five minutes. subsequent inspection of all the brake lines revealed severe corrosion and pitting at many locations along the length of the truck. despite having the front and rear brakes on separate hydraulic circuits, there was not enough braking capability remaining to safely drive the truck, even at low speeds. this was a very close call and it is evident that the corrosion resistance of the brake lines is substandard, posing a huge safety concern.

Had hooked truck to a car trailer and stepped on brakes to put truck in drive and brake pedal went to floor, there was no brakes at all. upon examining i found that three brake lines had failed. the truck was towed to a local garage and they found that all brake lines and also the fuel lines were badly rusted and had to be replaced.

Upon starting the vehicle and depressing the brakes, the brakes went to the floor. upon inspection from a mechanic, it was noted that both brake lines were rotted (one was rotted all the way through causing the fluid to leak from the line). we were also told that the gas line and caliper had severe rotting. upon my research, this seems to be a very common problem with chevrolet trucks. i hope this will be resolved so additional chevrolet owners do not have severe accidents due to these issues. my husband and 4 year old son had to walk quite a few miles in 95 degree weather! this is a safety issue and i hope my complaint will help further the investigation. *js *tr

While driving at approximately 15 mph i applied the brakes to stop and the brake pedal went to the floor. i immediately used the emergency brake to stop. i was right around the corner from my residence so i drove the truck back home using the emergency brake to stop. when i got home i checked the brake master cylinder and the fluid was low. i refilled the master cylinder and had my son pump the brakes as i was under the truck looking for any visible fluid leaks. all of the brake lines were severely corroded and the drivers side rear brake line had ruptured near the frame rail. after repairing the brake line at the point of rupture we re-filled the master cylinder and began to bleed the brakes and the brake line ruptured again at a point under the drivers front seat.

Brakes failed wile driving, had to use mechanical emergency brake to stop. completed stop across two traffic lanes, on coming traffic stopped in time to avoid accident. brake lines "rusted" through and blow out letting all brake fluid sprayed out onto street. *tr

I was coming to a very slow stop when the brake pedal went almost to the floor. i tested the brake several times while moving very slowly, and the pedal continued to go to the floor with a swooshing sound. i had someone check underneath the vehicle while i depressed the brake pedal, and he confirmed that brake fluid was shooting all over. my truck is 9 years old but it has only 50,000 miles, the original tires and has had only 2 brakes replaced just recently i believe that it is premature for the brake lines to have suffered a complete blowout. my former chevy truck which i had for 13 years had no problem with brake lines. *tr

My brake pedal went to the floor as i was backing my truck up to hook up my boat. when i got out of my truck there was a puddle of brake fluid under the truck on the drivers side. when i inspected where the leak was coming from it was from severely rusted brake line that burst. the other brake lines are rusted as well. i have no brakes what so ever. i would not have been able to stop if this had happened while driving especially towing my boat. *tr

when i got home today i noticed a clear puddle under the drivers side rear axle. upon investigating the underside of the truck i spotted a hole in the brake line. i followed the line toward the front of the truck and found several places where the line was severally corroded. this is plainly the result of inferior materials used by gm in their vehicles. *tr
