Seven problems related to brake master cylinder have been reported for the 2001 Chevrolet Suburban. The most recently reported issues are listed below.
2001 Suburban - when I applied my brakes coming to a stop sign the brake pedal went almost to the floor leaving me barely any braking power, but fortunately since I was driving at a slow speed (25 mph) I was able to stop in time. I then drove to a garage which was very close to where I was and had them put it up on the rack to look at it. They informed me that all of my brakes lines were very rusty and the one rear line had broken, I left it there and had that line replaced but after replacing that line another 2 lines broke during their testing after the first repairs. I ended up having 3 rear lines and the 2 lines to and from the master cylinder replaced (3 that broke and 2 other ones that looked really bad) at a cost of about $800, I am now going to get the remaining 2 front brake lines replaced "before" they brake on me also. These 2 lines are the hardest to replace and I was given an estimate of about $700-$800 to replace them. The one mechanic told me that a couple of years earlier his brake lines also broke on his Suburban coming up to a red light and he had to drive on the birm to avoid rear ending the car in front of him. He had to replace all of his Suburbans brake lines. I live in western PA and have been driving here for almost 40 years with many different vehicles during that time but I have never had brake lines rust and break like this. From what I have been reading, this must be from faulty brake line material, none of my many other vehicles have ever had this happen so chevy cannot just blame it on living in a snow/road salt area. *** I plan on going with a different manufacturer when I get my next SUV.
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.
Brake failure. Metal brake line between master cylinder and caliper developed a leak due to corrosion of the metal brake line. Mechanic said all metal brake lines were rusted and corroded and needed to be replaced. I understand there is an investigation underway on these faulty lines. The replacement of these lines was very expensive and was definitely a premature failure in my opinion. Luckily my 20 year old son noticed the brake pedal was going to the floor while on the interstate and was able to safely exit the highway. If the line would have failed a few minutes earlier, he would have been in a crash.
Was driving vehicle on a 2 lane public road at approximately 35 mph when pedal suddenly became soft and required many actuation to stop. Vehicle was unable to stop in the anticipated distance and a collision with cross-traffic nearly occurred. On investigation, the master cylinder reservoir was empty and there was leaking from multiple brake lines from corrosion.
The contact owns a 2001 Chevrolet Suburban. The contact stated that when applying the brakes, the brake pedal was depressed into the floorboard. The vehicle did not respond and the contact drove into the curb to prevent a crash. The vehicle was towed to a local mechanic who performed a diagnostic and located the failure as a ruptured brake line, caused by corrosion. The mechanic replaced the brake line and the master cylinder. The failure and current mileage was 113,854.
While towing my travel trailer back from a trailer inspection I noticed the brake on my 2001 chevy 2500 Suburban for uncomfortably close to the floor. Upon arrival after slowly limping home using mostly the trailer brakes I found that a rear brake line had ruptured and the rear master cylinder tank was empty. A local auto shop cut the line and added a new section. Per the mechanic the ruptured line is rusted along with the adjacent lines. The cut out section was thrown out before I could save it.
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.
