Modern anti-lock braking systems are highly reliable, and offer safer stopping in certain driving conditions. They’re also very complex systems that rely on a network of sensors, switches, and other components in order to operate. The ABS system actually spans most of your vehicle, although much of it is found under the hood, centered on the master cylinder. In an anti-lock brake setup, pressurized fluid must be stored in order to provide a power assist to brakes during ABS pulsing. The fluid is pumped into and held in the accumulator, and the anti-lock pressure switch is responsible for turning the pump on and off.
Essentially, the anti-lock pressure switch is an on/off switch for the ABS pump. When the fluid in the accumulator is low, the switch turns on the pump. The pump runs until the accumulator is full, and then the switch turns it off. However, over time, the switch can wear and failure is a possibility. When this happens, the pump will not operate, or it could burn itself out in some situations.
The anti-lock pressure switch is a small but important component for the entire ABS system. If it fails, the system won’t work, although you’ll still have normal braking capabilities but not the ABS. Have any brake system problem diagnosed by one of our expert mechanics as many different problems can set a code in the computer and turn on the ABS light on the dash.
Without a functional anti-lock pressure switch, the ABS pump cannot operate properly, and the system as a whole will shut down. Damage to the pump is possible in some instances. If you have an ABS light on in your dash or have noticed any other abnormal operation, have it diagnosed and replaced by one of our expert mechanics immediately.
