Your mechanic will carefully examine your Anti Lock Brake Parts valve assembly, as well as the rest of your car’s brake system. The best way to ensure that the ABS valve assembly is working properly is by following the manufacturer’s recommended requirements to maintain your system, including changing brake fluid. The ABS valve assembly is responsible for regulating brake fluid pressure going to each brake mechanism on the wheels on your vehicle. Finally, your cars Anti-lock Braking System (ABS) makes sure too much braking force is not applied to one wheel. An anti-lock brake system, ABS, is a system designed to keep you from locking up the brakes, or applying too much brake pressure to them, that your axles, and the wheels themselves, will stop turning entirely. The ABS Module is the microprocessor that performs diagnostic checks of a vehicle’s anti-lock brake system and controls the ABS modulator. It processes information from an ABS wheel-speed sensor and controls the pressure of brakes via an ABS modulator. The ABS module usually comprises the electric motor, the ABS valves operated with solenoid actuators, and the base on which brake lines are connected (from master cylinder to the brake calipers on each wheel). The ABS module is really made up of three components, an electrical module with an electrical solenoid, brake hose blocks, and pump motors which create pressure in the brake lines for use in ABS brake situations. The ABS management module controls the wheels speeds, and limits brake pressures on the callipers, should braking become severe, in order to preserve steering capability. The ABS module releases brake pressure very briefly to one tyre, to allow that tire to recover traction. The ABS management module has an important job to ensure you are able to drive the vehicle if a panic stop occurs. If the rest of the brake system is working, you should generally still be able to get a regular brake with no ABS. First, make sure that this is indeed an ABS light, and not one indicating a problem with normal brakes. Sometimes, a problem with the Traction Control lights will also trigger the ABS lights, but other times, it is an issue with your system. If only your traction control light or ABS light is on, then it is very possible that your system has been turned off by accident. Four common reasons that usually trigger this light include an ABS module failure, low fluid levels in your reservoir, broken wheel speed sensors, or the system being turned off. If the ABS sensor senses the car is sliding or losing traction, it sends a signal to the ABS module to quickly re-pressurize the brakes. When braking, ABS sensors sense the wheel’s speed, and they send a signal to the ABS pump to quickly activate — i.e., engage and deactivate — the brakes, as speed indicates the vehicle is skidding or losing traction. ABS sensors inform a computer (called the controller) when a wheel stops spinning during the movement of a car, indicating the brakes are locked on that specific wheel. ABS can plow these brakes more quickly than a race driver could, and ABS can route this pulsed brake pressure toward the particular wheel that has locked up. The entire point of the ABS system is to keep the brakes from locking in difficult conditions and situations, giving you more grip. If the ABS system is not working correctly, your car is more likely to slide, aquaplane, and lose traction under harsh braking conditions. Because the ABS assembly is part of the car’s braking system, it may impact your ability to steer and stop the vehicle under adverse weather conditions. If your brakes are locked under normal driving conditions, it could be caused by a bad ABS pump.
