A complete loss of braking ability, ruptured brake lines. Lines between proportioning valve and ABS pump ruptured and failed completely. Lines rusted and failed. No accident and no injuries. My wife was driving, vehicle was operated in reverse {backing up}, she then shifted to forward, brakes failed, pedal went to floor, and rolled from a parking lot into a highway, fortunately no other traffic was present.

The red brake light is on. The ABS module is not allowing the two rear brakes to work. The A/C control box in the dash blows hot air through the driver side only. In fl that is dangerous because of the heat already.

Brake flex lines between ABS and master rusted and failed, twice, within 2 years, brake lines rusted out between 90-106 k miles, gm does not make the parts anymore, and aftermarket parts are sketchy quality from china! Poor design, cheap steel lines, too thin, and no support of their products! Clearly gm has a myriad of other recalls and failures, but these are brakes, a critical part and safety component in vehicles that are supposedly their bread and butter- if your going to design safety parts to comport with federal requirements, support the product for reasonable use which is 25 years, better designs. 3 brake failures in 3 years, over $1800 now and no peace of mind it will not fail again.

As I was backing my vehicle from my driveway I noticed a puddle of brake fluid where the vehicle was parked. Upon closer inspection I noted that the front brake line leading from the master cylinder to the rear ABS controller was leaking fluid onto the roadway. The vehicle is no longer safe to drive until the brake lines are replaced. All of the brake lines on this 2003 suburban are heavily corroded and look ready to fail at any moment.

2003 chevy suburban 1500 4wd 5.3l, gm has a known issue with braking on these trucks where it takes too long to stop. I have replaced all pads, rotors, and calipers. Also performed ABS brake bleeding to see if air was in the ABS module/pump assembly. Truck still at times seems to not want to stop. It always takes a long distance to stop. There is no ABS activating during this time. This has been an issue since I bought the truck in 2007.

Tl* the contact owns a 2003 chevrolet suburban 1500. The contact stated when braking at low speeds, the ABS would independently activate. The failure progressed over time and would occur several times while in transit. The dealer advised that the ABS was defective and the sensors would need to be replaced. The vehicle was not repaired. The manufacturer was not contacted. Failure mileage was approximately 55,000 and the current mileage was approximately 60,000.

After an initial failure of the hydraulic brake (line ruptured about two feet behind the ABS valve) while the car was moving, and after this line was replaced, I inspected the rear wheel brake lines and noticed extreme corrosion on both lines that run from a junction connection above the differential to the hoses on each caliper. While checking the fittings and inspecting the left line it literally crumbled, broke and started leaking. I replaced both lines and bleed the system. The car had been into the dealer within last year (approx.) for brake line inspection after observing a lot of rust. The dealer claimed that lines were ok and that a lot of rust was normal and ok. I had to pay for this inspection.

When applying brakes to avoid hitting a deer, the pedal went completely to the floor. No ABS, no partial pedal, straight to the floor. Vehicle was towed to chevrolet dealer where it was determined that both front and rear brake lines needed to be replaced due to brake line corrosion. Dealer provided rough estimate of $1500 plus tax to repair.

Abs would incorrectly engage when stopping at low speeds (< 5 MPH). Increases stopping distance since ABS starts pumping instead of just applying brakes. This happens on ideal road conditions and at low speed/non skidding stops. *tr mechanic replaced wheel hub assembly on both front left and front right wheels (wheel hub included new ABS speed sensor). Problem was fixed. This is obviously a safety issue. Gm has already recalled 99 - 2002 (mine is a 2003) suburbans for this. Mechanic indicated that ABS sensors were badly corroded (presumably) from salt getting into contact with the sensor. Mechanic also indicated that he has fixed this in *many* suburbans and in many cases that came after owners had unsuccessfully tried to get dealers to fix the issue. Mechanic said dealers were replacing the ABS computer, at a cost of thousands of dollars, and problem still wasn't fixed. Important note: it appears that regardless of whether a recall is done, dealers should at least be aware of this common safety problem with suburbans from this time period.
