Vehicle: 1998 Oldsmobile Achieva 2.4 L4 GAS
System Operation
The function of the Anti-Lock Brake System (ABS) is to minimize wheel lock-up during heavy braking on most road surfaces. The system performs this function by monitoring wheel speed and controlling the brake fluid pressure to each front wheel and both rear wheels during braking. This allows the driver to retain directional stability and better steering capability.
System Components
