ABS system comes on at low speeds without brake pressed-vehicle then is hard to stop and pulls to the right. I have replaced all pads and calipers.machine bled system and replaced left frt speed sensor. Took to dealer and was told that the front hubs are exposed and most of the time tear apart and cleaning solves. Am upset the dealer charged a diagnostic fee for something he could have told me on the phone!

Caliper slides froze due to tolerance/corossion, causing vehicle to effectively utilize one brake pad for braking. Dealer noted that this is a common problem and offered to charge me for filing (service bulletin # 99-05-24-001) down the caliper slide to be within tolerance (not covered under "bumper to bumper" warranty - Chevrolet customer service file #000014560). According to Napa brake installation istructions for applicable pads (GM part numbers 7024A or 7081A), there is a posssibility of this condition breaking contact between the pad friction material and the metal backing, which would severely hamper or remove all braking power from that wheel. I have a brother with a Chevy astro van of similar year, and an uncle with a full size Chevy truck of similar year, both of whom have experienced front brake excessive/uneven wear. Thier vehicles were out of the warranty period at the time it was noticed. I feel that Chevy has denied me a warranty claim, because this is an inherent problem with thier brake design, and would be too costly to recall. I also feel that because it involves the front brakes (which provide most of braking power) of many large vehicles, that many use for towing, this should be considered for a safety recall, or at least covered under warrany, if discovered under warranty period. Thank you for your time.
