Hydraulic Parking Brake problems of the 1998 Chevrolet P30

Auto park/emergency brake, system on gm p-30 chassis pressure switch goes out applying the emergency brake either, while moving or parked. At moving speeds it immediately stops you in seconds potentially allowing someone to crash into you from behind because of the sudden stop. Many owners have had this problem, they are on the internet asking for help and don't know where to go. This is serious!!!.

The hydraulic auto park brake system failed. Vehicle had to be repaired twice. On second repair swiches, relays and the pump were replaced. However, problem still exist, the pump runs excessively and the light stays on intermittently.
