On 11-30-2015 I lost the brake system while driving on a city street. Upon inspection I found a ruptured brake line from the primary side of the master cylinder. The brake line had failed due to corrosion. Inspecting other brake lines, I found others that had corrosion where plastic clips were used to locate lines. I have owned this truck since new and have cared for it meticulously. The truck has 66,00 miles on it. I have never owned any vehicle that had it brake lines rust through like this. A major catastrophe to me and my family was averted by pulling over at the first sign of failure. Gm should be held liable for every vehicle it manufactured with poor quality materials that can cause failure to the single most important part of an automobile, the brakes. As you can see from the attached photos, this truck is not rusted anywhere else.

Parking brake
- What is wrong
- On certain pickup trucks equipped with manual transmissions and built with either pbr parking brake systems or trw parking brake systems, the parking brake friction linings may wear to an extent where the parking brake can become ineffective in immobilizing a parked vehicle.
- Risk
- If the parking brake does not hold, unintended vehicle movement could occur, which could result in a crash.
- Remedy
- Dealers will install a low-force spring clip retainer for vehicles equipped with a pbr parking brake system. On vehicles equipped with the trw parking brake system, dealers will install a redesigned parking brake cable assembly. The recall began on july 29, 2005. Owners may contact chevrolet at 1‑800‑630‑2438 or gmc at 1‑866‑996‑9463.
Recall number 05V161000 · Recall details
Service brakes, hydraulic
- What is wrong
- Certain trucks, sport utility vehicles, and vans equipped with bosch hydro-boost brake assemblies, the hydraulic brake booster pressure accumulator may crack and separate from the hydro-boost assembly during normal operating conditions.
- Risk
- If a separation occurred and the hood of the vehicle were open, fragments from the accumulator could cause injury to people in the immediate area. The presence of this crack or fractured surface could allow the hydraulic fluid to leak from the accumulator circuit of the booster assembly. The loss of fluid would cause increased steering and braking effort and a crash may occur without prior warning.
- Remedy
- Dealers will test the hydro-boost assembly for functional operation of the two-function valve. If the hydro-boost assembly fails the test, dealers will replace the assembly free of charge. The recall began on march 23, 2005. Owners may contact chevrolet at 1‑800‑630‑2438, gmc trucks at 1‑866‑996‑9463 and hummer at 1‑800‑732‑5493.

Most recent owner complaints, unedited.
Vehicle was stopped. Brake peddle went to the floorboard. Not able to pump up any pressure. Investigation showed brake fluid coming from perforated brake line at left front wheel. No braking action available! Appears to be some type of corrosive reaction between the brake line and the clamps used to fasten the line to the chassis. Note: this vehicle has never been operated in snow or road salt to my knowledge.
Brake failure do to rusted out lines.a ongoing problem that gm will not take responsibility for the poor quality of these lines putting people's lives at risk.
Without any warning, my brake lines failed and I could not stop my truck. I live in the northeast and it would seem reasonable for brake lines to rust out. However, my truck is only 10 years old and I have spent thousands of dollars keeping it washed, including the undercarriage. I have never had a brake line fail on another car and I have driven some really old vehicles. I have also never heard of anyone I know having a problem with their vehicles. This is because it is a specific problem with gmc sierra and chevy silverado.
A vehicle approaching from my left side was speeding and ran the stop light in front of me at approximately 40mph. I slammed on my brakes to avoid the collision and my brakes wet to the floor. I missed hitting the car by about 1 foot. At an inspection at a dealership it appears the brake lines had rusted through under the drivers side of the truck. Apparently form road salt corrosion,
Another gm rusty brake line failure while attempting to stop on a 2005 gmc sierra 1500. I don't expect things to last forever, but brake lines are essential to the safety of a vehicle and they should not be rusting to failure at this point. I don't care what the climate is. At this point my truck is in the shop getting fixed on my dime (gm refuses to repair it). But they need to look into this. I have worked on/driven many much older cars in the same condition, and I have never seen brake lines rust to this extent in 10 years. My last car was a 20 year old monte carlo that still had original brake lines. In my opinion this has the potential to turn into bigger safety issue at some time. In my opinion, it is only a matter of time.
Went to stop at stop sign, brakes felt spongy. Stopped up the road about 2 miles at my moms house to get my kids, looked under the truck and saw brake fluid dripping down on the left side of the frame behind the left front wheel.I have to replace all of my brake lines now due to rust.
When trying to exit highway offramp brakes completely failed due to brake lines rusting through. Vehicle was brought to a stop with parking brake.
I was traveling at 35 MPH and approached a stop light. The brakes failed and I went through the red light. I nearly was hit by oncoming traffic. The brake line has a sever leak at a rusted area in the line.
Around the middle of december 2014 the "service brake system" message appeared on my 2005 gmc 1500 sierra sle. I checked the brake fluid reservoir and it was nearly empty. I could not find where the fluid had leaked from so I serviced the reservoir with 12 ounces brake fluid to the full mark. From about december 15, 2014 until 28 december 2014, I lost about 7 ounces of brake fluid. No trace of brake fluid can be found on the driveway. I crawled under the truck and had my wife press the brakes while I looked for a leak. I found the leak near the left rear wheel area on a very corroded bracket. It appears to be a very small hole because the fluid comes out as a fine mist and not a stream. The rigid brake line connects to a flexible brake line at the bracket and there is a lot of rust at the connection as well as the brake line. I have found rust forming on other brake lines as well.
