ABS

Brakes are a critical safety item. To provide maximum stopping power, your brakes must be at optimum braking efficiency. Regular brake checks and maintenance are of great importance for the safety of your vehicle and help reduce the likelihood of much more costly bills in the future.

VRS can also help with all your ABS needs, including replacement sensors. Actual system failure is almost unheard of, while most often the problem arises when dirt gets into the sensors, which activates the ABS light and shuts down the system.

What is ABS?

Anti-lock Braking System (ABS) is a safety system on motor vehicles which prevents the wheels from locking while braking. An non-locking braking system allows the driver to maintain steering control under heavy braking, by preventing a skid, and allowing the wheel to continue to forward roll and create lateral control, as directed by driver steering inputs.

Since it came into widespread use, ABS has made considerable progress. Recent versions not only handle the ABS function itself (i.e. preventing wheel locking under braking), but also traction control, brake assist, electronic stability control amongst others.

The ABS system consists of two subsystems:
The hydraulic system, consisting of the master cylinder, callipers, wheel cylinders, pads, shoes and associated connecting valves, lines and hoses, as in a conventional brake system. The ABS controller (computer), its associated sensors (INPUTS), actuators (OUTPUTS), required wiring and connectors.
The computer receives signals from the individual wheel sensors regarding the speed of each wheel. It then compares the speed of each wheel with that of the others. If that comparison indicates wheel lockup is present, appropriate signals are sent to the various valves and actuators to raise or lower hydraulic pressure to the individual wheels to correct the skid. This action is repeated thousands of times per second, producing maximum stopping ability under all conditions. All of this activity goes unnoticed by the driver unless a component fault is detected by the computer and the “BRAKE” or “ABS” warning lights are illuminated on the dashboard.
