Rear-wheel ABS works by using a sensor to monitor the speed of each rear wheel. If the sensor detects that a rear wheel is about to lock up, the ABS system will automatically reduce the brake pressure to that wheel. This allows the wheel to continue to rotate, which helps to maintain stability and control.
Rear-wheel ABS is a valuable safety feature that can help to improve the safety of your vehicle, especially when braking on slippery surfaces.
