Applied brakes to stop in a parking lot. Brake pedal held briefly then went to the floor. Minimal stopping ability at that point. Narrowly missed a suburban which backed out of a parking space in front of me. All brake lines are severely corroded. Requiring replacement of all lines.

I needed to slow down on the belt parkway and when I applied my brakes, the pedal went straight to the floor. Figuring I may have some brakes, I attempted to brake again. There was no response other than a sickening feeling that I would rear-end someone. To slow down, I dropped the gear shifter to lower drive positions and put on the 4-way flashers. Upon exiting the parkway, I was barely able to stop for the traffic light. Fortunately no one was ahead of me and there was an uphill grade to slow me. Visual inspection of the brake system revealed hydraulic fluid soaking the area of the rear diferential on the driver's side. A hard steel brake line was severly rusted and fragile to the point of rupture. There was still some fluid in the master brake reservoir.

I noticed wet spots on the road under the truck near the left rear wheel after stopping. After further investigation I noticed that the brake lines are corroded in most places. There is currently a leak in the feed line running to the back brakes at a point near the left rear wheel. The lines look as if they could fail in most places. Currently the truck is nots drivable until the brake lines are replaced. We have had other numerous brake issues with this vehicle as well.

I pulled out of my driveway, and found that the brake pedal went to the floor. I was able to get back into the driveway. Upon inspection, I found that the brake line junction behind the left front wheel is leaking due to corrosion.

I began to notice that while executing low speed stops (city driving, stop and go traffic) my ABS system would activate and the pump could be heard and felt in the braking system. This occurred in all types of driving conditions, particularly on dry pavement and at low speeds, where ABS is not needed. The result of this ABS activation was decreased stopping power at unpredictable times. This created a safety hazard and almost caused several accidents. I ended up deactivating my ABS system completely to create a reliable braking system. When I took the car in for repair the mechanic stated that this was a known issue with this particular model, however my vehicle was not a part of any recall.

There was a recall on gmc yukon xl 2500 series ABS system campaign id # 05v379000 where the ABS system will engage while braking causing increased braking distance and potential crashes. The problem occurs in the 1500 series as well why was there not a recall for this series which I have and have the same problem with? I called the gmc hotline and my local dealer and they tell me there are no recalls for my model and I don't drive my vehicle because I fear rear ending someone or rolling into an intersection when attempting to stop.

Pulling horse trailer with 2001 gmc yukon xl, brake pedal went to floor, took long distance to stop. Made it back home, saw dripping brake fluid around left rear wheel well. Put truck on floor jack, pulled wheel. Applied brake, observed brake fluid squirt from pinhole in severely corroded brake line (the line attached to the top of the rear axle on driver side). The hole is located in the steel brake line where it joins the junction with the flexible hose and the steel line running to the opposite wheel (near center of rear axle). Will replace line today, will keep old part (corroded line) available. All other steel brake lines have rust in places.

After turning off car notice the ABS pumps continues to run. Dealer states ABS control module needs to be replaced. The happened twice so far: 1st time at 45,000 miles with an estimated repair cost of $1200 and 2nd time at 113,000 miles with an estimated repair cost of $1325. This type of fail rate seems unacceptable especially to a safety component. The failed part is still in my possession.
