Use of brake

Due to the high speed on the highway, the braking reaction distance of the driver is significantly increased, and the braking and stopping distance of the vehicle is greatly extended, which makes the vehicle non-safety zone expanded, the braking effect becomes worse, and the safety of the vehicle driving It is greatly reduced. Even if the braking performance of the service brake is good, when the brake is emergency at 100 kilometers per hour, the side slip phenomenon will occur, causing the car to lose control. Especially on rainy days, the car runs on a highway with a certain thickness of water film. Due to the high-speed rotation of the tire, the water accumulated on the road cannot be eliminated in time. The resistance of the water will cause the wheel to float. Water film slippage occurs.

The water film effect completely fails the driving force, braking force and directional control of the car, which brings serious harm to safe driving. In addition, the density of vehicles on the expressway is high, and the speed of the vehicle is high. Sudden emergency braking will cause the following cars to collide with the vehicle ahead of time before braking. Therefore, when driving on the highway, the driver should fully understand the braking distance, estimate the braking stopping distance, decelerate in advance in case of situations, and avoid traffic accidents caused by excessive braking. The correct braking method is: during driving, the driver must anticipate the sudden situation, first raise the accelerator pedal, use the engine's restraining resistance to slow down, and then gently depress the brake pedal to reduce the vehicle speed. That is, the method of braking first and then lightly makes the car stop quickly.
