Today we are talking about How Anti-Lock Brakes Work . Now a days mostly cars have ABS system. ABS is a life saving technology which allows driver to heavy breaking with in-control steering.
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.
ABS system consist following parts -
1. wheel speed sensors
2. Brake calipers
3. hydraulic motor
4. pressure release valve
5. Control module
Working :-
When brakes are applied this pressurises a hydraulic system which causes the brake pads to close against the discs which causes the car to slow down. If the ABS system detects that one wheel is slowing down more rapidly than the rest (a symptom of wheel-lock) it automatically reduces the brake pressure on this wheel by opening a pressure release valve in the hydraulic system. It also has the ability to build the pressure back up via the hydraulic motor.
