Can a Faulty ABS Pump Cause Brake Pressure Loss?

[JosiahMarie]

abs pump failure can cause brake pressure loss. The function of the ABS pump and the working principle of the ABS system are introduced as follows: Function of the ABS pump: The function of the ABS pump is to prevent wheel lock-up. In most vehicles, it starts working at speeds above 18 km/h. The ABS pump receives signals from ABS sensors on each wheel, which are then sent to the ABS control module. The ABS control module then commands the ABS pump to operate, rapidly pumping and releasing brake fluid to achieve anti-lock braking. Working principle of the ABS system: The ABS system operates in two modes: mechanical and electronic. It not only enables vehicle braking but also prevents wheel lock-up during braking, allowing the vehicle to maintain steering and mobility while braking. This system can reduce braking distance, minimize hydroplaning, enhance vehicle stability, decrease tire wear, and extend tire lifespan.
