GENERAL INFORMATION
Vehicles equipped with an Antilock Brake System (ABS) use a system designated ABX-4 and is supplied by Bendix. This system shares the base brake hardware with vehicles not equipped with ABS. A vehicle equipped with ABS does however use a different vacuum booster, master cylinder and brake tubes. Also included in the ABS system is a Hydraulic Control Unit (HCU), four wheel speed sensors, and an Electronic Controller Antilock Brake (CAB). These components will be described in detail in Antilock Brake System.

The hydraulic brake system is diagonally split on both the Non-ABS and ABS braking system. With the left front and right rear brakes on one hydraulic system and the right front and left rear on the other.

The master cylinder is anodized, lightweight aluminum. On vehicles equipped with front disc brakes and rear drum brakes, the master cylinder bore is 21.0 mm. On vehicles equipped with four wheel disc brakes, the master cylinder bore is 7/8".
