BRAKE SERVICE PROCEDURES FOR 1992 GMC Yukon AUTOMOBILES
Anti-lock Brakes -> Rear Wheel Anti-Lock Brake System -> Description -> 1992 -> 1993 S & T Series -> 1993-94 C & K Series & 1994-95 S & T Series
Vehicle: 1992 GMC Yukon 5.7 V8 GAS
1992
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 rec...

Vehicle: 1992 GMC Yukon 5.7 V8 GAS
Do not smoke or allow an open flame of any type when working on or near any fuel system related components. The highly flammable vapor mixtures may ignite, resulting in serious personal injury.
Prior to disconnecting fuel lines, the fuel system pressure must be relieved to prevent accidental spray of fuel.
After the battery has been disconnected and reconnected, some abnormal driveability symptoms may occur. The vehicle may need to be driven while the vehicle relearns its adaptive strategy.
