Air Brake Antilock problems of the 1997 Chevrolet Blazer

The vechile was coming up to a stoplight. My daughter was driving my 1997 chevy Blazer. She pushed down on the brakes and nothing happened. She tried again and still nothing. She and my younger daughter crashed into a semitruck trailer. The police estimate her speed at 28 mph. There are no skid marks. The brakes did not work.

The brakes failed on the vehicle and caused a minor accident due to slow traveling speed in parking lot. I have contacted the manufacturer that admits a fault in the abs system, but does not claim responsibilty for the damage. I am not mechanically inclined, but believe this to be a serious problem.

Abs brake light was on for 26,000 miles & could not be shut off by dealerships with at least four attempts. Brakes wore out pre-maturely. Brakes continue to be very spongy & sometimes goes almost to the floor with difficulty stopping. Brake booster also replaced. Dealerships say that's the way Blazer brakes are. These brakes are dangerous.

Excessive brake wear (replaced twice in 2 years). Often hard to stop. Grinding/thumping and then skids when brakes applied in 4wd.

This is a 1997 Chevrolet bazer. The anti lock brakes on this vehicle is defective and ingages under varying conditions. The vehicle is unsafe in slippery conditions. Front sensors have be checked. This vehicle will engage anti-locks at times when brakes are not applied. Brake switch checks ok. Pedal will drop under most stops and anti-lock will scream and apply. A jerking brake action is present. I do know there is a recall on 1994-1996 models. By looking on the internet I see that I am not alone in this problem. Hubs are ok. I think the trouble may be in the control unit, but no trouble codes appear and scan tool indicates no trouble. I think gm has produced defective units. This car has 90000 miles but has had excellent care and no damage. I would like to know how to disconnect these anti-lock brakes. They are unsafe. There appears to be no way to detect the problem.
