Cadillac Repair: Parking Brake Release, vacuum release valve, vacuum line

Question
I have a 1992 Cadillac Sedan DeVille that when I put the car into reverse or drive, the parking brake no longer releases by itself.  Is there any way I can fix the brake so it releases on its own again?  Right now I use the manual release, but I have a bad back and it hards to reach under the dash that far.

Answer
Your problem is either:


1. Loss of vacuum to the vacuum release valve on the sterring column under the dash.

2. A faulty vacuum release valve.

3. a disconnected vacuum line from the vacuum release valve to the vacuum actuator at the parking brake assembly.

4. A faulty vacuum actuator at the parking brake assembly.


I can e-mail you pictures of these items and how they are hooked up but you will have to contact me at:
