Brakes Failed problems of the 2005 Chevrolet Cobalt

I experienced "catastrophic" brake failure while driving my 2005 chevy Cobalt lt sedan w/automatic transmission on the highway. I was forced to make a sudden emergency stop from approx 45mph to 0. The abs system worked perfectly as the roads were wet and I did not lose control resulting from my sudden stop, with the abs and traction control instrument lites illuminating. However upon quickly trying to resume travel (since I was straddling 2 lanes on the highway) the brakes would not "release" and fearing a rear end collision from approaching traffic, I shifted into 1st gear and simply drove 15' to the shoulder, fighting against the "grip" of the brakes. On the shoulder, with the abs & tc lites still on, I was safely able to repeatedly shift in and out of park and repeatedly pumped the brake pedal until finally after approx 1min they released their grip and the abs & tc lites turned off allowing me to resume travel. I traveled for approx 10 min at 65mph w/cruise control, when suddenly an alarm sounded with the abs & tc lites illuminating again. I traveled approx 1mi before exiting the highway to investigate the alarms and their meaning. I entered the off ramp at approx 60mph and attempted to slow the vehicle but the brake pedal simply went straight to the floor with no pressure! I quickly repeated the action with the same result. Fearing a hydraulic loss, I began pumping the brakes with no success. Simultaneously I downshifted to 2nd however due to the near 60mph speed this had no effect as the automatic transmission will not downshift until reaching a safe rpm level for that gear. My final resort was using the parking brake which only slowed the car to approx 25mph until they also became inoperative with smoke billowing from the rear wheels. I ran through the intersection, finally stopping 1/2 way up the opposing on-ramp, thankfully due to the slight incline.

Brake failure/brake pedal went down when applied and vehicle accelerated at a high rate of speed,traveled 20-25 feet struck truck in front of me causing over $4,000 in damage to my 2005 chevy Cobalt since the June 13th 2007 accident the brakes failed 2 more times the last time the brake pedal collapsed to the floor with no brakes(bushing &clip missing from brakes, I think this was done at the factory). I had to stop it using the emergency brake. I refused to drive it again. My wife had it do this to her, with the brakes failing and accelerating at a fast pace, luckily no cars were near her at the time,because I traded the Cobalt general motors refuses to do anything about the problem reference number 71-562139648 talked to several people one was jake ext 22795.

: the contact stated while driving 10 mph the power steering and power brakes failed. The power steering and t-c lights on the dash illuminated. This happened three times. The vehicle was towed to the dealer were an unknown computer part was replaced. Updated 06/23/06.
