Four omens before brake failure how to deal with the brake failure of the vehicle in driving

if the brake suddenly fails during driving, it is likely to cause vehicle damage and death, so mastering some emergency methods may save the day. Generally speaking, the brake failure is mostly found when the car is going downhill, and it is only found when the car is going downhill, especially when there is no brake when going downhill. Let’s have a look at it.

Four omens before brake failure

the brake is biased

this phenomenon is that when the brake is pressed in driving, the steering wheel will deflect like one side. The main reason for this phenomenon is that the force distribution of the brake cylinder on the brake pad is not uniform, resulting in serious eccentric wear of the brake pad.

brake pedal travel longer

in the previous car, press the brake pedal brake response is very fast. Now it takes a deep step to get the braking force, which means that the brake pedal travel has become longer, that is to say, the brake is soft. The reason for this situation is that the oil pressure of master cylinder or slave cylinder is insufficient, and there may be oil leakage.

The brake makes an abnormal noise

. Generally speaking, it’s normal to make an abnormal noise when you step on the brake after the rain or when you go to wash the car. This is due to the expansion of heat and contraction of cold. But if there is an abnormal noise when you step on the brake, it may be the problem of the brake pad.

will shake when stepping on the brake pedal

if stepping on the brake pedal in normal driving, the pedal will shake seriously, which indicates that the surface flatness of the brake pad may be inaccurate. In particular, some vehicles with a long age have a higher probability of this situation.

1. According to the road conditions and speed, control the direction, get rid of the high speed gear, and quickly switch the high speed gear into the low speed gear. In this way, the engine will have a lot of traction resistance, so that the speed will decrease rapidly. In addition, in the low gear at the same time, should be combined with the use of the handbrake, but pay attention to the handbrake can not be taut, nor too slow. If it is pulled too tightly, it is easy to make the brake disc & lt; Hold on & quot;, It is likely to damage the transmission parts and lose the braking ability; If it is pulled too slowly, the brake disc will be worn and ablated, and the braking effect will be lost.

2. Use the bumper, carriage and other steel parts of the car to rub and collide with the natural obstacles (rocks, trees or soil slopes) on the roadside, so as to achieve the purpose of forced parking and escape, and reduce the accident losses as much as possible.

3. In case of brake failure when uphill, it is necessary to reduce to medium and low gear in time to keep enough power to drive up the top of the slope and stop. If you need to stop at half slope, you should keep the forward low gear, tighten the hand brake, and the personnel on board should timely block the wheels with stones, skids, etc. In case of back sliding, the rear of the vehicle should face the hillside or safety side, and turn on the headlights and emergency signal lights to attract the attention of the front and rear vehicles.

4 When the downhill brake fails and the vehicle’s own mechanism cannot be used to control the speed, the driver should decisively use natural obstacles, such as rocks and trees on the roadside, to cause resistance to the vehicle. If you can’t find a suitable terrain or object to use at the moment, you can close the side of the car body to the side of the mountain in an emergency to increase the resistance by friction and gradually reduce the speed.

5. When the vehicle is going down a long or steep slope, it should step on the brake regardless of whether there is any situation. It can not only test the braking performance, but also gain the time to control the speed when the brake fails, also known as predictive braking.

if it is uphill, then the problem will not become a problem. As long as the oil is collected, there is no reason not to stop. However, at this time, we should pay attention to one thing: because the uphill is definitely in gear, we should prevent the car from sliding backward. We should pay attention to the movement of the car behind, and try to make a good direction to avoid collision with the car behind. If the car behind is closely following, we should add some more oil and try to pull over to stop and collect the oil.
