Antilock Brake System

ANTILOCK BRAKE SYSTEM





This vehicle uses an antilock brake system designated System 8. For this vehicle, the antilock brake system comes standard with Electronic Stability Program (ESP) and All-Speed Traction Control.


This antilock brake system uses components of the base brake system, but also features the following components:

- Integrated Control Unit (ICU) (1) - Hydraulic Control Unit (HCU) and Antilock Brake Module (ABM)
- Wheel Speed Sensors (WSS) - Four sensors (one at each wheel)

The is made up of the Hydraulic Control Unit (HCU) and the Antilock Brake Module (ABM).


ABS


The purpose of the antilock brake system (ABS) is to prevent wheel lockup under braking conditions on virtually any type of road surface. Antilock braking is desirable because a vehicle that is stopped without locking the wheels retains directional stability and some steering capability. This allows the driver to retain greater control of the vehicle during braking.


All vehicles use Electronic Variable Brake Proportioning (EVBP) to balance front-to-rear braking when the brakes are applied in the partial braking range.
