Part of your car's Anti-lock braking system, ABS rings play a crucial part in the process which allows you to maintain control of steering, enabling you to brake easily by regulating the air pressure in the wheel brakes.
ABS rings actually look like cogs and are located behind each of your car wheels.
As the ABS rings spin around they work together with the ABS speed sensors to detect when your wheel is about to lock and potentially skid by measuring the amount of hydraulic pressure required. A message is relayed to the ABS Control Unit ECU which adjusts the brake pressure to ensure your car wheels don't lock up, allowing you to control your car and preventing your car from skidding and sliding.
Due to the fact that it is constantly spinning, this part suffers from friction damage, which will eventually cause it to malfunction. Damaged ABS rings are inefficient at best, but could also cause the anti-lock braking system on your car to stop working. If your ABS rings are faulty, the ABS warning light will illuminate and it is advisable to sort the problem out as soon as possible. ABS rings are fairly simple to fit and replacing them with quality ABS rings you can be certain that the part will be compatible with the make and model of your car.
