ABS System Parts

Wheel & Speed Sensors, Hydraulic Units, Actuators, Relays & Sensors

Driving on slippery roads can be hazardous if your ride doesn’t have an anti-lock braking system (ABS). ABS helps keep the brakes from locking up. It is a common misconception that the primary purpose of ABS is to shorten stopping distances. While that may occur, its real purpose is to allow the driver to maintain steering control by keeping the front tires rolling. In vehicles without ABS, the driver must manually pump the brakes to avoid wheel lockup.

A brief history of ABS reveals that it was first developed in the 1920’s for aircraft, was tested in the 1950’s for motorcycles, but was not put into production for passenger cars until the early 1970’s. Even then there was very limited availability, typically as an option on expensive luxury cars. It was not until the late 1980’s that the automobile industry began to embrace widespread application of ABS for passenger vehicles. By the start of the 21st century, the system was standard on the majority of new cars and trucks. Some light-duty trucks have had ABS installed only on the rear wheels.

The functioning principle of ABS requires that an electronic control unit (ECU) know the rotational speed of each of the four wheels. If the control unit senses that one or more wheels experiences a rapid reduction in speed, it interprets this as a wheel about to lock up. The ECU informs the hydraulic modulator to release brake pressure to that wheel or wheels. Doing so allows the wheel to rotate. If the wheel slows down again, the process repeats. The beauty of ABS is that it can perform this brake off/brake on cycle many dozens of times per second, much faster than any driver could by pumping the brakes.

In addition to the ECU and the hydraulic modulator, the other major components of the ABS are the wheel sensors, the toothed wheels, a dashboard warning light, and the hydraulic and electrical lines to connect all the components. It is important to note that under hard braking, the driver will likely feel a pulsation in the brake pedal. This is normal and is not a cause for concern. It is just as important to remember that a driver should not pump the brakes on an ABS-equipped car! If severe braking is necessary, the driver should press firmly on the brakes and let the system do its job.

ABS rarely requires any maintenance or upkeep from the vehicle owner. Of course, the driver should be aware of any changes to braking operation. An illuminated warning light should be investigated as soon as possible. A common issue is damaged electrical wires or connections at the wheel sensors. Sometimes, the sensors or the toothed wheels are adversely affected by dirt or corrosion and require replacement. The driver should see the ABS warning light if one of these components becomes defective. Stay aware of how your brakes function, because you want your ABS to operate perfectly to keep you safe.
