System Operation
Anti-Lock Brake System (ABS)
The ABS system will control hydraulic pressure in the individual wheel circuits to prevent any wheel from slipping. A separate hydraulic line and specific solenoid valves are provided for each wheel. The ABS can decrease, hold or increase hydraulic pressure to each wheel brake. However, it cannot increase hydraulic pressure above what the master cylinder is transmitting.
Enhanced Traction System (ETS)
The ETS limits wheel slip during acceleration when one or more of the drive wheels are accelerating too rapidly and the brake switch is off. T...

Disc Brakes -> AC-Delco Single Piston Rear Disc Brake (Type 2) -> Troubleshooting -> Brake Roughness
Vehicle: 2002 Chevrolet Impala LS 3.8 V6 GAS
Brake Roughness
The most common cause of brake chatter on disc brakes is a variation in disc thickness. If roughness or vibration is encountered during highway operation or if pedal pulsation is experienced at low speeds, the disc may have excessive thickness variation. To inspect for this condition, measure the disc at 12 points with a micrometer at a radius approximately one inch from edge of disc. If thickness measurements vary by more than ...

Hydraulic Brake Systems -> General Motors -> Description -> Brake Distribution Valve & Switch -> Brake Warning Lamp Switches -> Combination Valve -> Components -> Diagonally Split System -> Failure Warning Switch -> Fluid Level Sensor -> Front & Rear Split System -> Metering Valve -> Proportioning Or Pressure Control Valve -> Warning Lamp
Vehicle: 2002 Chevrolet Impala LS 3.8 V6 GAS
Front & Rear Split System
When the brake pedal is depressed, both the primary (front brake) and the secondary (rear brake) master cylinder pistons are moved simultaneously to exert hydraulic fluid pressure on their respective systems.
If the rear (secondary) brake system fails, initial brake pedal movement will cause the unrestricted secondary piston to bottom in the master cylinder bore. Primary piston movement will displace hydraulic fluid in the primary section of the master cylinder to actuate the front brake system.
If the front (primary) brake system fails, initial brake pedal mo...

Power Brake Units -> Description -> AC-Delco Single Diaphragm Type -> AC-Delco Tandem Diaphragm Type -> Toyota/GM Single Diaphragm Type
Vehicle: 2002 Chevrolet Impala 3.8 V6 GAS
AC-Delco Tandem Diaphragm Type
This unit utilizes a vacuum power chamber, consisting of a front and rear shell, housing divider, front and rear diaphragm, plate assemblies, hydraulic pushrod and a diaphragm return spring, Fig. .
In normal operating mode, with service brakes in released position, the booster operates with vacuum on both sides of its diaphragms. When brakes are applied, air at atmospheric pressure is admitted to one side of each diaphragm to provide power assist. When the service brake is released, atmospheric air is shut off from one side of each diaphragm. The air is ...
