ABS is an abbreviation for Anti-lock Braking System. Anti-lock brakes are designed to keep cars from going into a skid when the brakes are applied in an emergency. Designed to allow the driver steering control, ABS brakes work by automatically actuating the brakes on and off during emergency stops. They are effective in helping drivers avoid accidents.
ABS was introduced in the mid -1980s and has become “standard” equipment on the majority of vehicles sold in Canada. ABS in cars and most multi-purpose vehicles (MPV’s) and pick-up trucks works on all four wheels. This promotes directional stability and allows steering while maximizing braking.
An ABS system consists of the following components:
- Some wheel speed sensors
- Brake calipers
- A hydraulic motor
- Some pressure release valve
How ABS Work ? A quick thinking computer (or control module) which coordinates the whole process When the driver hits the brakes this pressurises a hydraulic system which causes the brake pads to squeeze 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. ABS also has the ability to build the pressure back up via the hydraulic motor. The system reacts remarkably quickly, and compared wheel speeds many times a second. ABS systems can act on just the front wheels (which do most of the braking work), or all four depending on what car you’re driving.
Advantage-The advantages of ABS brakes (anti-lock braking system), are just as the meaning of their acronym implies, they eliminate or greatly reduce the possibility of brake lock up and therefore provide a better chance of steering out of trouble.
ABS system is very useful in slippy condition likes stopping the vehicle on Ice, its also the important advantage of ABS.
