Brake Disc Caliper Problems of Chevrolet Astro

Uneven wear of brake rotors due to frozen calipers. Rotor becomes unevenly worn causing a pulse in brakes and reducing the effectiveness of the brakes. When examined further it is apparent that the caliper is not sliding properly and only the piston side of the brake system is being applied aggravating the problem further. Problem was a primary cause for loss of control in a low traction incident in which the van spun during panic braking when one rear wheel locked and the other didn't. The vehicle has been back to the dealership several times for brake problems and each time the vehicle was returned only to redevelop problems within a month or two. Dealer serviced vehicle one time as warranty but required payment for pads even though the premature wear was caused by this problem. This van is advertised with a towing capacity of 5000 lbs I would be scared to see what would happen if the problem manifested itself while towing a 5000lb trailer down a hill or moutain side.

The abs brake system is unpredictable. If one side or the other is in loose gravel, rough surface, or slick surface and brakes are applied hard (like a child running out in front of you), the opposite side will lock up and cause the vehicle to slide in that direction. This problem is intermittent and only happens part of the time. Likewise, when slowing down (as in approaching a stop sign) the brakes will pull the vehicle across a crowned centerline if firm grip is not maintained on the steering wheel. Again, this only occurs intermittently and only after the vehicle has been driven a distance and is "warmed-up". Also, the vehicle will lock-up one front wheel (usually the left front) during a panic stop on dry, smooth pavement and either pull the steering wheel out of your hands or slide the vehicle sideways. This also happens intermittently. The dealer has replaced the left side caliper, replaced the right side caliper, and replaced the abs module on the kelsey hayes abs system. Gm now says that the vehicle is operating at manufacturer's spec's. I feel the van is unsafe because you don't know what is going to happen when you hit the brake pedal--will it stop straight, or pull left, or pull right, or (in fast "panic" stop) lock up one side and slide in that direction.

Vehicle developed a random pull while braking, particularly in rain or snow & slush. In the beginning it was only the first time you applied the brakes after you drove 2 or 3 miles then it happened on dry pavement. It happens only occasionally, but can be very severe, it nearly pulled me into the guide rail on one occasion. This started around 12000 miles and it now has 46000 miles on it. The dealer has replaced pads, turned rotors, aligned the front end twice, and ground the clearance on the calipers twice. At gm denied having more complaints about this but I have heard of other paople with the problem. I was called by the dealer the other day to bring it in again to lower the front end and another alignment. I recently took it on a trip in which my brother inlaw drove it and asked me "have you noticed this thing pulling?" my wife also drives it and has complained to me. This vehicle has a problem , and I suspect there are others! I had a 1992 Astro awd but never had the problem. A friend of mine traded her Astro awd off because it had a similar problem, but pulled to the left, into oncoming traffic. I 've been lucky so far, but it could easily cause an accident because on some of the severe incidents it has pulled me off the edge of the road.
