BRAKE SERVICE PROCEDURES FOR 1991 Oldsmobile Silhouette AUTOMOBILES
ANTI-LOCK BRAKES, GENERAL MOTORS -> Rear Wheel Anti-Lock Brake System -> DESCRIPTION
Vehicle: 1991 Oldsmobile Silhouette 3.1 V6 GAS
The Rear Wheel Anti-Lock (RWAL) system, Fig. , reduces the occurrence of rear wheel lockup during severe braking by regulating rear hydraulic line pressure. Pressure applied to the rear wheel brakes is regulated by a control valve assembly located under the master cylinder. The control valve consists of a dump valve which releases hydraulic pressure into an accumulator, and an isolation valve which holds rear brake pressure. Operation of the dump valve and isolation valve is controlled by an Electronic Control Unit (ECU) which is mounted next to the master cylinder.
The ECU receives ...
