Since most cars on the road today have some form of Anti Lock Brakes (ABS) I think we should take a look at how they work and clear up some misinformation about them.
As always, what I describe here is how most systems work in general. Since different manufacturers have their own versions of ABS their specifications and part names may differ. If you're having a problem with the ABS on your vehicle
you should always refer to the specific service and repair manuals for your vehicle.
The ABS is a four-wheel system that prevents wheel lockup by automatically modulating the brake pressure during an emergency stop. By preventing the wheels from locking, it enables the driver to maintain steering control and to stop in the shortest possible distance under most conditions. During normal braking, the ABS and non-ABS brake pedal feel will be the same. During ABS operation, a pulsation can be felt in the brake pedal, accompanied by a fall and then rise in brake pedal height and a clicking sound.
Vehicles with ABS are equipped with a pedal-actuated, dual-brake system. The basic hydraulic braking system consists of the following:
ABS hydraulic control valves and electronic control unit
Brake master cylinder
Necessary brake tubes and hoses
The anti-lock brake system consists of the following components:
Hydraulic Control Unit (HCU).
Anti-lock brake control module.
Front anti-lock brake sensors / rear anti-lock brake sensors.
Anti-lock Brake Systems (ABS) operate as follows:
When the brakes are applied, fluid is forced from the brake master cylinder outlet ports to the HCU inlet ports. This pressure is transmitted through four normally open solenoid valves contained inside the HCU, then through the outlet ports of the HCU to each wheel.
The primary (rear) circuit of the brake master cylinder feeds the front brakes.
The secondary (front) circuit of the brake master cylinder feeds the rear brakes.
If the anti-lock brake control module senses a wheel is about to lock, based on anti-lock brake sensor data, it closes the normally open solenoid valve for that circuit. This prevents any more fluid from entering that circuit.
The anti-lock brake control module then looks at the anti-lock brake sensor signal from the affected wheel again.
If that wheel is still decelerating, it opens the solenoid valve for that circuit
