One problem related to power assist brake vacuum has been reported for the 1997 Chevrolet S10. The most recently reported issues are listed below.
After only 4 years and less than 77,000 miles, this p/u experienced a failure in the diaphragm inside the brake booster unit. I have owned numerous vehicles for 10 or more years, both domestic and foreign, however, this is the first chevy. It is also the first, out of seven(7) to have this type of failure, period, much less this early. Have there been other reports of similar failures in the 1997 s-10 series? if not, can a survey be run to check?.
