I would add that the 4 wheel disc air over hydraulic work fine. They just use air pressure instead of vacuum because of the diesel engines lack of engine vacuum.

The parking brake is on the transmission output . Pulling the yellow dash knob dumps the air from an actuator , allowing a spring to set the brake.

Had to reply to this one . I had this problem on a 2000 Reflection . I found the bracket on the transmission that holds the parking brake "works" had loose mounting bolts. Tightening those fixed the brake and a transmission leak.
