Model Years Affected: 1990, 1991, 1992, 1993, 1994, 1995, 1996, 1997, 1998, 1999, 2000, 2001, 2002, 2003

Average Mileage: 92,333 mi (38,000 mi - 149,000 mi)


The parking brake may not release automatically due to a failed vacuum switch or actuator. Our technicians tell us that if vacuum is supplied to the actuator when the transmission is in gear, the vacuum switch is functioning and replacing the actuator should correct this concern.

    I have had the problem since the mileage hit 95000. How much does this cost to repair?

    Emergency brake does not retract all the way back. I have to reach under the panell and pull a small lever to get it to fully release then slightly pull the brake back manually. This is on the 92 base model seville.

    Parking brake will not release automatically HVAC blows in defrost mode. I will look into the location of the probable vacuum leak.
