Good To Know

Q: What are the signs of a faulty parking brake pump switch? A: Symptoms include the auto-park brake failing to release, the brake light staying illuminated on the dash, or the pump motor running continuously.

Q: Can a bad switch cause the parking brake to lock up? A: Yes, if the switch fails to signal the pump to generate or hold pressure, the spring-applied brake may remain locked on.
