An anti-lock braking system (ABS) is an automobile safety system that allows the driver to maintain control of the vehicle. It allows the wheels to maintain higher traction with the road surface according to driver inputs while braking, preventing the wheels from locking up and avoiding uncontrolled skidding. It was introduced in the mid-1980s and now has became “standard” equipment in the majority of vehicles.

It was designed to help the driver maintain some steering ability and avoid skidding while braking, which was practiced by skillful drivers with previous generation braking systems. It does this at a much faster rate and with better control that many drivers could manage. It allows to steer the vehicle and still maintain braking.

Since different manufacturers have their own versions of ABS and their names may also be different. The ABS and non-ABS brake pedal feel are the same during normal braking but the vehicles with ABS are equipped with a pedal-actuated, dual-brake system. The anti-lock brake system has the following components:

1. Hydraulic Control Unit (HCU)
2. Anti-Lock Brake Control Module
3. Front Anti-Lock Brake Sensors/Rear Anti-Lock Brake Sensors
