One problem related to brake antilock control unit/module has been reported for the 1999 Chevrolet Astro. The most recently reported issues are listed below.
Comments: why did everyone miss the 1999 chevy Astro van with awd? I already had the front wheel bearings replaced (at my cost) earlier this year for the same problem!!! parts are no longer available, but local firestone garage performed the maintenance, and has the records of the service. Near-miss too many times at low speed stopping problems. Some one needs to include the chevy & GMC Mini-vans!!!.
