ABS bounces badly when driving and braking in snowy days. What happened?

ABS is an anti-lock braking system. If the wheel is locked, it will lose control.

When it rains and snows, the friction between the tire and the ground decreases, and it is easy to lock the wheel when braking. Once the wheel is locked, the ABS system will begin to unlock and maintain the power of the car. Therefore, ABS is easy to start when braking in rainy and snowy weather.

When ABS is started, due to the frequent locking and loosening of wheels, the brake pump frequently releases the braking force, which causes the oil pressure to rebound to the brake pedal, so the vehicle pedal is felt to vibrate.

Remember that this is not to release the brake pedal to avoid vacuum power failure. Brake pedal vibration is a normal phenomenon when ABS is started. Only by maintaining the braking force and controlling the direction can braking be effective.

ABS is not omnipotent, because the wet road in rainy and snowy weather will increase the braking distance. Be sure to drive carefully and slow down as much as possible to avoid danger.
