When the brake fails, the driver must first remain calm and calm, and don't panic. The correct measure is to quickly downshift while controlling the direction according to road conditions and vehicle speed. In the high gear, enter the direct gear and then quickly enter the middle gear. At this time, the engine will have a lot of traction resistance to reduce the speed quickly. At this time, you can brake by hand and then quickly enter the low and lowest gears, and then manually control Automatically control the vehicle to stop. If the effect of the hand brake is not good, you can also use the hillside to force the vehicle to stop or control the vehicle at low speed to gradually stop on a flat road. When the uphill brake fails, reduce to the middle and low gears at the appropriate time. Keep enough power to drive up the hill to stop. If you need to park on a half slope, you should keep the forward low gear, tighten the hand brake, and the vehicle crew should use stones, skids and other items to jam the wheels in time. If there is a back slip phenomenon, the rear of the vehicle should face the hillside or a safe side, and Turn on the headlights and emergency signal lights to attract the attention and avoidance of the front and rear vehicles. Here, it should be pointed out that the measure of leaning directly on the hillside without slowing down is extremely dangerous. High-speed and violent scratching will directly damage the vehicle and easily be collided and overturned by the rebound of the hillside, and there are no hillsides in many sections, so It is wise and correct to use the traction resistance of the engine to control the vehicle speed, and the shift synchronization device of modern vehicles also provides convenience and reliability for fast and forced gear grabbing.
In addition, it is worth mentioning that when the vehicle is going down a long slope, the brake should be lightly stepped on regardless of the situation when the vehicle is on a steep slope. The advantage is that one is to check the braking performance, and the other is that once a braking failure is found, it can win the control of the accident Time, reduce panic, and control the vehicle calmly. In fact, this is also called predictive braking. You must not underestimate this predictive braking. Various failures may occur during the driving of the vehicle, and the brake failure is no exception. Predictive braking can help us turn danger to safety in the event of a sudden failure.
