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 as vehicles not equipped with ABS. The ABS system does however use a different master cylinder and chassis brake tube assembly. 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 the Antilock Brake System (ABS).

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 used on all vehicles equipped with or without Antilock Brakes is made from a lightweight, anodized, aluminum. On all vehicles the master cylinder has a piston bore diameter of 22.2 mm.
