Brake lines between the area of the brake fluid reservoir and ABS modulator heavily corroded. One or more lines failed on 7/10/2016 requiring vehicle tow. Vehicle was operational aside from the failure of braking system. When depressed, vehicle brake peddle had little resistance and traveled completely to floor panel under normal pressure from foot. The incident/failure occurred during normal travel and during an attempted stop at red light. Brake system failure prevented a safe stop and the vehicle continued through the intersection running a red light. Fortunately, the intersection was clear and no accident occurred. The vehicle was parked immediately afterwards and a tow vehicle called. The vehicle is currently parked until repairs can be applied. Towing expense- 125.00 parts expense- 85.00 (replacing all affected lines, front braking system.) labor- 100.00 approx.

What owners say
The metal brake line between the ABS modulator valve and front right wheel ruptured when the brake pedal was pressed. The line failed due to corrosion. All brake lines in the vehicle had similar levels of corrosion near the area the aforementioned line ruptured, and at various other locations on the vehicle. A brake line between the master cylinder and ABS modulator had failed in a similar mannner approximately 8 months previously. The transmission cooler lines had also failed due to corrosion approximately 2 years ago. The corrosion and rust on many other components beneath the vehicle and in the engine compartment is rather concerning. Power steering lines (including power brakes, since the vehicle has hydro-boost brakes) appear to be next. All metal brake lines were replaced immediately after the most recent failure for an owner cost of about $500. It is my understanding that the federal safety agency recently closed an investigation of brake line failure due to corrosion on several gm trucks and suvs. After about 4 years, this investigation determined that "a safety-related defect has not been identified at this time." apparently they don't read the complaints on their own website...
One of the metal brake lines between the master cylinder and the ABS modulator valve ruptured during a stop due to corrosion. All brake lines in the vehicle have similar levels of corrosion near the area the aforementioned line ruptured, and at various other locations on the vehicle. The transmission cooler lines had failed approximately 18 months previously due to corrosion. The corrosion and rust on many components beneath the vehicle and in the engine compartment is becoming rather concerning.
Coming to a stop light the brake pedal went to the floor. Only way I could stop was by using the electric brakes on my trailer to stop the combined vehicle. Examination revealed a rusted brake line coming from the brake master cylinder to the ABS module at the ABS module under the vehicle. Further examination revealed that the 4 brake lines from the ABS module to the wheels were all rusted/pitted and about ready to rust through.
2001 suburban k2500 complete loss of braking due to corrosion and rupture of brake lines from master cylinder to ABS unit and from ABS unit to right front wheel. This is the same problem as current investigation pe10010.
While driving my 2003 k2500 chevy suburban, another vehicle pulled out in front of me from a side street while I was traveling about 35 MPH and I pressed the brakes very hard - hard enough to lock up at least one wheel, but avoided an accident. I continued on, but just a few seconds later, I approached an intersection, and the brake pedal went to the floor, with very little braking power. I was able to get the vehicle stopped by pumping the brakes quickly and ran slightly into the busy intersection. I pulled into a parking lot to inspect whether I had damaged something. I decided to return home about 1/2 mile away and slowly drove home, with very little braking power. When I got home, I crawled under the vehicle to find brake fluid splattered and leaking all over the underside around the ABS unit. The brake lines are extremely corroded, and I suspect one has blown out. The vehicle is in very good and well maintained condition otherwise, but the underside seems particularly rusty. If I were traveling more than the 30-35 MPH I was, there would have been no way to stop the vehicle. A serious accident would have occurred. These are very common vehicles, if this is typical, a safety recall must be initiated.
Tl*the contact owns a 2004 chevrolet suburban 2500. At low speeds, he would depress the brake pedal but the vehicle would not respond accordingly. It seemed that the ABS would activate and cause him to move a few feet forward. The ABS also increased the stopping distance and almost caused the contact to crash on two occasions. He took the vehicle to the dealer but there were no codes produced. The vehicle has not been repaired to-date. He called the manufacturer and asked if they could include his vehicle in recall 05v379000 but was informed that his model year was not included. The current mileage is approximately 80,300. The failure mileage was approximately 76,000. Updated 2/22/10 *cn updated 05/17/10.
I have a 2001 chevrolet suburban 2500 that has a bad ABS module that I have been trying to get replaced since july, so that my ABS breaking system will work. The module has been back ordered at the factory since july. This makes for an unsafe vehicle for my wife & family on a daily basis. This week was a very scary week because we were driving through colorado springs and had to stop fast because of traffic and the breaks locked up and the suburban started to turn sideways, my whole family of 6 was in the car. This is frustrating because there is nothing I can do to get the parts or fix the car.
I'm having an ongoing ABS system problem that is the same problem that recall 05068 had. As I slow to a stop my ABS system kicks on below 10 MPH but above 3 MPH. When the ABS system kicks on it is a load grinding noise followed by a decrease in controllability and a pulling to the right of the vehicle. The recall 05068 only covered 2000-2002 suburban years, mine is a 1999 k2500.
Tl*the contact owns a 2003 chevrolet suburban 2500. While approaching a stop or slowing down to make turns at low speeds, the ABS activates without warning. The contact is unable to safely come to a complete stop. The manufacturer stated that her VIN was not included in the federal safety agency campaign id number 05v379000 (service brakes, hydraulic: antilock). She will take the vehicle to the dealer for repair. The current and failure mileages were 88,000.
