Highway maintenance vehicle traveling in the process of foot brake step down, but it does not seem the same response continued to travel, if such a situation occurs brake failure of the majority of drivers will be thrown into a panic them. When this happens, we cannot panic. We can take the following measures to ensure the safety of our lives and property.
1. Control the steering wheel according to the driving conditions and speed of the road surface. Take the gear away from the high speed gear, and at the same time, quickly throttle the throttle (there is no gear so it is empty oil) and then hang in the low gear.
In this way, the engine will have a lot of traction in the low gear situation to make the speed of the vehicle lower. In addition, while using the engine to reduce the speed, do not forget to use the handbrake, which should pay attention to the handbrake can not pull too tight, can not pull too slow. If you pull too tight, it is easy to make the brake disc "locked", it may cause damage to the transmission components and thus lose braking capacity; if you pull too slowly, it will make the brake disc wear increased, resulting in ablation and thus Loss of braking effect. If it is an automatic transmission model, you can switch to manual mode, reduce the gear, use the engine to slow down, and gently pull the handbrake to slow down and stop.
2. Use road maintenance truck bumpers, carriages and other steel parts to rub against natural obstacles such as rocks, trees, and slopes on roadsides to achieve the purpose of further forcibly parking and minimize accident losses.
3. When the brake is uphill, there is a brake failure. It should be reduced to the middle and low gears in due course and keep enough power to drive the vehicle up the hill and stop. If you need to stop on a half-slope, you should keep the low gear forward and tighten the hand brake. The occupants quickly use the stones to block the four wheels. If there is a phenomenon of backsliding, the rear of the vehicle should face the slope or the side of safety, and turn on the vehicle signal light to cause the attention of the front and rear vehicles.
4. When the downhill brake malfunctions and the vehicle braking device cannot be used to decelerate, the driver should quickly block roadside natural obstacles such as rocks, trees and earth slopes to cause resistance to road maintenance vehicles. If there are no suitable obstacles that can be used, in case of an emergency, one side of the body can be brought closer to the mountain edge to obtain friction and gradually reduce the speed.
5. When the vehicle is on a long slope or a steep slope, it should avoid excessive speed, and it is necessary to step on the brakes from time to time. It can not only detect the braking system performance, but also can win the time when the brakes are found to control the speed, also known as predictive braking.
