ABS pumps play a key role in a vehicle’s braking system. When the ABS pump is malfunctioning, the brakes may become less responsive and the vehicle will take longer to stop, especially on wet or slippery roads. In addition, your car may pull to one side when braking, as the ABS system will not be able to provide even braking pressure on all four wheels. This can be particularly dangerous when taking corners or changing lanes. Finally, the ABS light may come on, warning you that there is a problem, and you may have to pay for expensive repairs if the issue is not addressed quickly.
