ABS or the anti-lock braking system is a feature of the vehicle braking system. Most of the latest vehicles have an ABS module as a default feature as it performs smoothly compared to the normal braking system. The ABS is composed of the pump, controller, solenoid valves, and ABS sensors which can be found at each wheel. Depending upon the configuration of your car, the ABS sensors will be present on all four wheels or only on two wheels.
The ABS is responsible for controlling the movement of the vehicle. It prevents the wheels from locking up during heavy braking situations to prevent skidding in adverse weather conditions. A faulty ABS module can be potentially catastrophic especially during monsoons when the roads are slippery. For this reason, it is important to conduct routine maintenance of the ABS and ensure that it is in perfect condition at all times.
