Report: Vacuum Brake Release Switch Can Fail
Cadillac DeVille Problem
Average Mileage: 119,881 mi (55,000 mi - 196,000 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.
