2006 GMC Sierra 2500: brake failure

Filed Jun 5, 2020 · Brakes · 147,000 miles · KS

Brakes failed "completely", with no warning. No "warning light" on the instrument panel while driving on a public road in the county. All of a sudden absolutely no brakes. Had recently hauled a car on a trailer from emporia, kansas. Was preparing to haul calves to the sale barn. Now that would have been a total disaster. Upon inspection, the brake lines are so rusted, that pinching off the line resulted in a rupture in another location. I was trying to get some braking action, so I could drive it to a repair shop. I'll have to haul it.

Brake lines busted. This is a very serious problem because I was hauling a load and got extremely extremely lucky that it busted as I was pulling in driveway. I was pulling a loaded trailer with no brakes. This is a very common issue with the 2005 and 2006 2500 trucks. I can name 6 vehicles I know of in the past 6 months that this has happened too. Mechanic says it's a very serious and common issue that gm should be recalling. If I would have been at a stoplight it would have been bad. Cheap materials is the problem with these brake lines. 2006 year model is mine.

In the city stopping for a stoplight the brakes failed. The vehicle luckily was able to turn into a parking lot. All fluid was lost because the brake lines failed due to rust. No brakes whatsoever except emergency brake. My state even requires a safety inspection yearly. If the consumer is not going to be notified of this serious problem at least let the safety inspectors know.

Brake failure caused by corroded brake lines.

Brake line ruptured due to corrosion which was not visible during safety inspections. After applying brakes to stop at an intersection, brake line broke, causing a complete loss of brakes and loss of vehicle control. I had to use the transmission and the emergency brake to stop the truck. Several local mechanics commented that they are seeing an increase in the number of this type of failure on similar model years. With no failover system to stop the truck, this should be listed as a safety issue.

While driving I noticed smoke coming from under the hood and a fluid dripping onto the floor of the truck. Then there was absolutely no brakes. Pedal to the floor. I was able to get it into a parking lot and coasted in neutral til it stopped on a parking curb. The brake line had rusted through and ruptured, and the fluid was spraying into a hole in the firewall and into the cab of the truck. This is the third brake line that has ruptured in such a manner. No warning at all, and then sudden loss of braking. The warning light did not come on until the truck had been sitting for over an hour while I was waiting for a tow, and a large amount of fluid had leaked out. I'm just glad this had happened at a low speed and not on an exit ramp from the freeway. The ruptures are occurring where the lines run flat across a support. This is a poor design.

I brought my 2006 gmc sierra 2500 hd in for a brake service as normal. Technician installed brakes and rotors and took truck for a test ride. As technician was bringing truck back from the test ride, brake line ruptured and split! This was the rear drivers side brake line located under a plate. Technician said he nearly crashed the truck into another vehicle and had to use the emergency brake and curb to stop the truck! With all the trucks out there, gm's trucks seem to have the highest brake line failure. I am writing to you to inform you of the problem that could endanger the lives of anyone driving the vehicle as well as the people around it! My hope is that gm sees there is a problem and corrects it before any fatalities arise from brake failure!

Total brake failure due to ruptured hydraulic brake line. No prior warning. Total failure, I thought dual master cylinder would provide some braking.

I am the original owner of this truck was on my way home from shopping, lights on the dash started blinking. I attempted to stop the truck not knowing what was wrong, the brake pedal went to the floor. I stopped the truck with the emergency brake. Opened the hood and the master cylinder was empty. I was close to home so I took the truck home using the emergency brake. I have this truck serviced by the dealer where we bought it new bob hook chevrolet and also montgomery chevrolet, who had just serviced this truck and nothing was said about low brake fluid or rusting brake lines. The truck is now in a repair shop waiting for parts. The truck is now not drivable and still at the repair shop.

Was ready to leave work,had foot on brake pedal,it felt spongy started truck,pumped it up it still felt spongy as I got to end of the road I was driving on I went to hit brake for stop sign/the brake pedal went right down to the floor and brake light/check idiot light and message came on dash,oil reminder as service brake failure came on up as the message. Barely was I able to stop had to shift truck to 3 low for additional engine braking as I got up to the intersection and almost blew through the stop sign,drove it bout a mile home,looked under truck and saw brake fluid shooting out and dripping off everything by the gas tank. Haven't driven it since.
