Recently reported SERVICE BRAKES problems on 2004 GMC Sierra 2500HD

During cold mornings (wisconsin) i start my truck and i have no power steering and soft brakes. it is my understanding that the power steering runs the brake boost. also, it is my understanding that there is a service bulletin that says that the power steering fluid should be replaced with low/cold temp fluid. my concern is what happens if i lose power steering and brakes while i am driving.

Pulling out of a parking lot, lost brakes. steel brake lines by fuel tank, let go causing truck to loose brakes

Tl* the contact owns a 2004 gmc sierra 2500 hd. while driving 10 mph, the brakes failed without warning. it was diagnosed that all the brake lines needed to be replaced. the manufacturer was made aware of the failure. the approximate failure mileage was 176,395.

I was leaving a parking lot, and as i hit my brakes, there were no brakes. i limped home, using the e-brake and transmission to keep the truck under control. upon inspection i found the front brake line rusted and leaking. *tr

All the fluid lines corroded to the point where the vehicle was dangerous to drive with only 35000 original miles on it. *tr

While traveling on the pa turnpike at approx. 60 mph, traffic suddenly slowed in front of me. i was pulling our 30 fifth wheel camper at the time. i applied the brake hard had a split second of braking action and then the brake pedal went to the floor. i was able to use the manual trailer brake control to slow the truck some, swerved into the left lane missing the car in front of me by inches and the car to the left of me swerved into the far left lane to avoid hitting me. (three lane highway) i managed to drive the truck to a rest area about a mile down the road using both the trailer brakes and the truck emergency brakes. the cause of the brake failure was that the brake line located under the drivers area had rusted through and ruptured. *jb

Tl* the contact owns a 2004 gmc sierra 2500 hd. the contact stated that while driving 40 mph, he applied the brakes but the vehicle did not respond. he continued applying pressure until the pedal touched the floorboard and finally, the vehicle came to a stop. the vehicle was taken to a dealer for diagnosis and the contact was informed that the steel brake lines exhibited massive corrosion and were leaking. the vehicle was taken to a different dealer where the repair was completed. the manufacturer was notified of the failure. the failure and current mileage was 80,000.

My vehicle had brake lines replace two times with less than 65,000 miles because breaks stop working. fuel line replaced under 55,000 miles because it made check engine light come on speedometer erratic,oil pressure gauge high and low,fuel gauge erratic under 65,000 miles. loud noise from engine service technician reported the exhaust manifold bolts has broken to call a white smoke from the motor. everything happened with consider to be low mileage in talking to gm they don't care because enough report has not been made.
