General Description

Under normal braking conditions, the Anti-Lock Brake System (ABS) functions as a standard brake system with a diagonally split master cylinder and conventional brake booster.

If a wheel lock is detected during braking, the system will enter ABS mode. During ABS mode, hydraulic pressure in the four wheel circuits is modulated to prevent any wheel from locking.

Each wheel circuit has a set of electrical valves to provide modulation to each wheel. Front wheels receive separate signals and rear wheels receive the same signal.
