One problem related to brake disc caliper has been reported for the 1997 Chevrolet Tahoe. The most recently reported issues are listed below.
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.
