Braking knowledge

How to use it correctly
There are generally two sets of independent braking mechanisms on the car, the foot brake and the hand brake. The purpose of using the brake is to force the car to decelerate quickly until it stops, or to maintain a certain speed when going downhill, and it can also be used to reliably keep a stopped car in place without slipping. In driving, the correct use of brakes is not only conducive to ensuring driving safety, but also conducive to saving fuel, reducing tire wear and preventing damage to parts. How should the brakes be used correctly? Will you use the brakes?
1. Predictive braking
The driver's early deceleration and braking measures for parking according to his own purpose or for the situation that has been found, called predictive braking. The method is to quickly lift the accelerator pedal, make full use of the engine's restraining effect, and at the same time lightly step on the brake pedal to reduce the speed of the car. When the car comes to a stop, step on the clutch pedal, put the transmission gear in neutral, and stop the car smoothly at the predetermined position.
2. Emergency braking
In driving, the braking measures that have to be taken in order to make the car stop quickly when encountering a sudden dangerous situation is called emergency braking. The method is to quickly lift the accelerator pedal and immediately press the brake pedal hard, and at the same time pull the handbrake sharply to make the car stop quickly. This method not only causes serious damage to the tires and chassis parts, but also is prone to tail flicking, which is not conducive to driving safety. Therefore, it should not be used in the case of a last resort.
3. Downhill braking
No one will deny that it is impossible to go downhill without braking, but downhill must not be completely dependent on braking. When going downhill, you should slow down and put on a gear that matches the speed of the vehicle. Only when the engine sound is unpleasant and the gear can not control the speed of the vehicle, it is supplemented by braking. The method is, for the air brake, the pedal should not be released too much with the step, to avoid reducing the air pressure too quickly. You should continue to step on the next stroke according to the required braking intensity; when you need to reduce the braking intensity, release the pedal a little. When going down a long slope, as long as the air pressure can meet the needs, appropriate intermittent braking can be used. In this way, the cooling of the brake hub and the brake shoes is facilitated. If you are driving a car with exhaust brakes, use them as often as possible. For hydraulic braking, after stepping on the brake pedal twice, press the pedal with your foot so that the pedal is in a high near-braking state. When you need to increase the braking force, step down a little more, and you need to reduce the braking force and lift it up a little. When the brake pedal height is gradually lowered, you can step on it twice to make the pedal height rise again.
4. downhill braking failure, use the hand brake
When going down a long slope, when the foot brake suddenly fails due to an accidental failure, it must be handled calmly. The "grab" method can be used to enhance the restraint effect of the engine. The method is to press the button of the handle brake lever and gradually tighten the handle brake lever, so that the speed of the vehicle is gradually reduced under the action of the hand brake. When operating, you can pull it, loosen it, pull it again, release it again, and repeat. When the vehicle comes to a stop, then fix the handbrake in the tightened position. It should be noted that the handbrake lever should not be tightened at one time, nor should it be pulled too slowly. It is easy to "lock" the hand brake disc or brake shoe due to tightening it, and it is easy to damage the transmission parts and lose the braking force; if it is too tight, the brake disc or brake shoe will be worn and ablated. Out of action.
5. Braking on muddy, rainy and snowy roads
When you need to slow down or stop when driving on muddy, rainy and snowy roads, you should use predictive braking as much as possible, use the engine's restraint braking effect as much as possible, use the hand brake flexibly, try to avoid foot braking, and never use emergency braking. brake to avoid an accident. Use the foot brake, use it intermittently, and do not kill it with one foot. Because the braking distance of muddy, rainy and snowy roads is much larger than that of ordinary dry roads, when using the brakes, you should brake according to the vehicle speed and road terrain, so as to slow down and slow down. During the braking process, once the whole vehicle slips, it is necessary to quickly release the braking and stabilize the direction. When a tail flick occurs, turn the steering wheel in the direction of the flick as appropriate, so that the vehicle returns to the straight driving position, and must not accelerate sharply. Get directions in case something goes wrong.
6. Soft Traction Driving Brake
When driving with soft traction, the vehicle ahead should try to avoid using the brakes unless there are special circumstances, and must not use emergency braking. If you want to stop, apply coasting braking to reduce the speed; Sound the horn to inform the car behind. The car behind should pay close attention to the movement of the car in front, and put your feet or hands on the brake pedal or handbrake. Once the car in front is braked, step on the pedal or apply the handbrake immediately. If the car in front brakes urgently, the rear car should turn the steering wheel while braking to make the front of the car deflect to one side of the rear fence of the front car to avoid a collision.
7. with trailer driving brake
The braking distance with a trailer is long and the synchronization is poor. The connection part of the traction device is easy to hit, and the acceleration performance after braking is poor. Therefore, when driving with a trailer, you should use predictive braking as much as possible, use the sliding and engine restraint to slow down, and when using foot braking, you should tread lightly and release slowly in advance.
In short, in driving, you should try to use predictive braking and avoid using emergency braking to ensure safe driving.
