System Operation
The Anti-Lock Brake System (ABS) minimizes wheel lock-up during heavy braking. The ABS monitors each wheel's speed and controls brake fluid pressure to each wheel independently. A separate hydraulic line and solenoid valve for each wheel allows hydraulic pressure to be modulated, preventing wheel lock-up. The ABS can decrease, hold or increase hydraulic pressure.
The system continuously monitors all components, using several methods to determine faults and notify the driver of malfunctions. When the engine is started, the ABS electrical circuit is checked. As the veh...

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...
