Brakes and Traction Control: Description and Operation

Typical brake equipment consists of:

Vehicles equipped with the optional Antilock Brake System (ABS) use a system designated Mark 20 and is supplied by Teves. 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 an Integrated Control Unit (ICU), four wheel speed sensors, and an electronic controller referred to as the Controller Antilock Brakes (CAB). These components will be described in detail in the Teves Mark 20 ABS brake section in this group of the service manual.

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 22.2 mm.
