The Design and Function of Antilock Braking Systems
By Tom Torbjornsen
Most passenger vehicles are coming out with, otherwise known as anti-lock brakes. Let's take a look at their design and function. ABS uses wheel-speed sensors, a hydraulic control unit, and a computerized electronic-control module, which is the "brain" of the system. When the brake pedal is applied, the electronic-control module monitors the speed of the wheels through the wheel-speed sensors. If the control module detects that one or more wheels are about to lock up, the module signals the hydraulic unit to control hydraulic pressure to that wheel(s). This varying of pressure is much like "pumping" the brake, but with the ABS system, the wheel that is locking up (causing a potential loss of control) is the only one being controlled. The rest of the wheels are free to roll. This maximizes vehicle steer-ability.
Aside from the addition of these components, the braking system pretty much remains the same in design and operation. Replacement of friction materials, such as brake shoes and pads, is the same. As with any new product, "bugs" or "gremlins" usually show up in the form of little nuisances during the first few years. In the case of ABS brakes, it is the annoying little dash light that comes on and says either "Brake" or "Antilock" or "ABS." "The brakes work fine but the light is on," you say. Vehicle manufacturers are well aware of this and, as we speak, are working on a solution to this annoying problem. It seems that when moisture and road salt find their way into the wiring harness -- either through cracked wire insulation or worn or loose electrical plugs, the light will be tripped because of high resistance sensed by the system. They are working on a way to waterproof the wiring harnesses effectively. In the meantime, all the computer knows is that it senses a problem in the system and must alert the driver via the dash light.
Am I saying to ignore the ABS warning light? Absolutely not! We're talking about safety here! Get it checked out! Traveling down a steep grade at 65 mph, coming up on the back of a loaded gasoline tanker truck is not the time to find out that your brakes don't work!
