Brake Fluid Leak Problems of GMC C2500

Upon starting in parking lot, brake pedal went all the way to the floor. Large puddle of brake fluid below cross member near starter. Back up system to isolate front or rear brake systems did not engage. Upon later inspection, I found the crossover brake line to the right front wheel had completely rusted through. The brake fluid reservoir completely emptied. All steel brake and fuel lines show serious rusting. (had to repair leaking transmission oil cooler lines last summer. ) this sudden brake line failure could have caused a dangerous accident, or even fatality, if it had occurred while I was driving. Just glad another family member wasn't driving when this happened.

We had driven about 90 miles from our main house to our lake house on Friday night-brakes were fine. Saturday morning we backed the sierra up and hooked up the boat to the hitch. After hooking up the boat while we were pulling out of the driveway the brake pedal went to the floor. We dropped the boat and drove the sierra a few miles to the store. While at the store we noticed a leak above the gas tank. The leak was brake fluid and the sierra took an entire bottle of brake fluid. We drove it the few miles back to the house and got the truck towed home the next day. When the gas tank was dropped we noticed rust so bad on the frame that a screwdriver went thru the frame. The frame could have busted apart right behind the cab of the truck. We were extremely lucky that there were no injuries.

I parked my vehicle and upon exiting observed fluid drips on the pavement. I touched and smelled the fluid and determined it to be brake fluid. I then observed fluid dripping from beneath the drivers side passenger compartment. I immediately checked the brake fluid res. And observed it to be below the 1/2 point. I was approximately 4 miles from my home and decided to take the back road which required less braking. The fluid was still leaking upon my arrival home. I should note there was no fluid leaking prior to departing my residence. I did notice the pedal travel to have increased and the feel to be slightly spongy as I drove down a steep grade requiring significant braking to maintain the 35 mph limit into havre DE grace. The vehicle (2001 GMC 2500hd) is not driven much and mostly for local (<15 miles) travel. The front rotors and calipers have been replaced and the lines bled approximately 2 months ago. There is rust evident on the brake lines. I might argue that due to the vehicle age this is to be expected; however, the extremely low mileage is equivalent to approximately three (3) years worth of driving. Having owned many vehicles, this is the first to have had such a problem. I now have the unscheduled expense of replacing the brake lines. I am lucky not to have been further from home where I might have experienced total brake failure possibly causing a crash.

The contact owns a 2001 GMC 2500 hd. The contact stated that he noticed a huge puddle of brake fluid under the vehicle. Upon further inspection, he was able to determine that there was a hole in the brake line and it appeared that the brake line was ruptured. In addition, the contact stated that the frame was completely rusted. The vehicle was not taken to the dealer for diagnosis. The contact wanted to purchase a stainless steel brake line and install it on the vehicle but he stated that it should have been the responsibility of the manufacturer. The failure and current mileage was 35,000.

During a tire rotation at costco , they discovered brake fluid leaking from the brake lines. Upon a further investigation ,the brake lines are leaking and found to be rusted out. I have been using the vehicle to tow a 2010 air stream and thank god no accident or injury has occurred.

Applied brakes brake light came on along with brake system service needed lost pressure on pedal and all lost fluid still had small amount of braking (brake lines corroded and leaked out fluid ,lines should have been made from stainless steel not cheap steel. ).

Brake failure. My brake pedal went to the floor I discovered brake fluid leaking onto the ground under the drivers side door. Upon further inspection I was shocked to find that my metal brake lines were corroded and burst leaving me with no brakes. Truck is 2001 sierra 2500hd with 64,000 miles. I have never seen metal brake lines fail like this .
