Anti-Lock Brakes -> Bosch Type 5.3 -> Description -> Brake Pressure Modulator Valve -> Electronic Brake Traction Control Module -> Pump Motor -> Pump Motor & Solenoid Relays -> Solenoid Valves -> System Components -> System Operation -> Wheel Speed Sensors
Vehicle: 2007 Buick Lacrosse CX 3.8 V6 GAS
System Operation
The Bosch Anti-Lock Brake System (ABS) with Traction Control System (TCS) minimizes wheel lock-up during heavy braking on most road surfaces to improve driver control. ABS monitors each wheel's speed and controls brake fluid pressure to each front wheel independently and both rear wheels simultaneously.
A separate hydraulic line and solenoid valve for each front wheel, and one hydraulic line and solenoid valve for both rear wheels allow hydraulic pressure to be modulated, preventing wheel lock-up. The ABS can decrease, hold or increase hydraulic pressure.
The system co...
