[Xiagong Chusheng original] China is a country with many mountains. Due to the landforms, most of the highways in China have large slopes. Daily driving, braking is particularly critical.
â— Â The major causes and treatment of brake failure
There are many causes of brake failure. Xiaobian simply classified it as follows.
 1. Abnormal brakes caused by insufficient maintenance
The lack of maintenance of the brake system usually leads to a major accident when the key is needed.
 Treatment method: always check whether the brake master cylinder, sub-pump, air reservoir and pipeline work well. Leakage and poor working conditions should be repaired or replaced immediately. At ordinary times, you should always pay attention to changes in air pressure on the instrument.
 2. Unreasonable operation methods lead to mechanical failure
Due to the lack of driving experience of the driver himself, the wrong operation of the vehicle causes the malfunction of the machine.
 Solution: When you are on a long slope, you must use a low gear to reduce the speed, use the engine to control the speed, use as little brake as possible to prevent the brake pad from overheating, and use a brake instead of a “boring stuff†when you step on the brake.
 3 serious overload, resulting in brake failure
With serious overloading, the total mass of the vehicle increases. Under the effect of the gravity acceleration, the inertia of the vehicle movement is increased, which directly results in the failure of the brake.
 Solution: Overloaded vehicles increase the overall mass of the vehicle, thereby increasing the inertia of the vehicle. When driving an overloaded vehicle, it must be slow. It is not possible to disregard life safety for rush.
â— Â Reasonable choice of auxiliary brakes to make driving safer
Exhaust braking has become standard on most cargo vehicles and should be used in conjunction with driving. In addition, we can also choose other auxiliary braking (such as engine braking, retarder, etc.) to make our driving more safe.
â— Â What to do if a brake malfunctions while the vehicle is moving
If the brakes have failed during the driving process, what should we do? Xiao Bian here summed up some experiences for your reference
 Calm mind
When we find that the vehicle has braked, the normal physiological response will cause us to "accelerate the heartbeat" and "the brain is blank." "I don't know what to do" will only increase the severity of the accident. At this time, you must let yourself calm down and think of ways to reduce the loss. Don’t worry about the big things.
 2. Grab the file quickly to reduce the speed
According to the road conditions and speed control a good direction, according to road conditions and technical level to grab, using engine resistance to reduce speed. (too steep road conditions and novice drivers to use with caution!)
3. Scratching and collision. Forcibly parking
In order to reduce accident losses, use scraps and collisions between rigid parts such as vehicle bumpers and carriages and roadside guardrails and natural obstacles (rocks, trees, and slopes) to achieve the purpose of forcibly parking out and reduce accidental losses as much as possible. .
4. Uphill brake failure handling
When there is a brake failure on the uphill, it should be reduced to mid-range and low-level gears, and keep enough power to climb to the top of the hill. If you need parking at half slope, you should keep the low gear in the forward position. The occupants will use the stones, padding and other objects to get stuck on the wheels. If the vehicle still slides back, the rear of the car should face the hillside or the safe side and turn on the headlights. And double flash warning lights, causing the attention of the front and rear vehicles.
5. Treatment of downhill brake failure
When a brake malfunctions on a downhill slope and cannot use the vehicle's own mechanism to control the vehicle speed, it must use obstacles, avoidance lanes, etc. in a decisive manner to cause resistance to the vehicle and cause parking. After parking into the reverse position, the front should be on the safe side.
6. Habitual check brake
When driving normally, the vehicle should habitually step on the brake when it is on a long slope or a steep slope. It can not only test the performance of the brakes, but also can win the time to control the speed when the brakes are found to be out of order.
7. No luck, personal safety is the most important
When vehicles cannot be controlled and accidents occur inevitably, personal safety should be given priority first. Try to minimize the damage to other vehicles and their own, and decisively choose to skip to ensure their own safety.
