Brake is also known as retardation. It can be simply understood as stopping or reducing the rotation. In a car, the term brake mainly refers to pressing the brake pedal, which is controlled by the right foot. The main way to achieve this is through the friction between the brake pads and the brake drum, which slows down or stops the vehicle. Whether it is a manual or automatic transmission, the brake踏板 is used to control the brake.

Brake is achieved through the fierce friction between the brake pads and the brake drum. When a car is driving in water, the wheels are almost immersed in water, leaving a layer of water film between the brake pads and the brake drum, just like applying a lubricant. This reduces the friction force and makes it difficult to control the car.

This phenomenon of brake failure occurs very quickly. When leaving the water and pressing the brake pedal repeatedly, the water droplets between the brake pads and the brake drum will be wiped off, and the heat generated by friction will dry them out, restoring the sensitive response of the brake quickly.
