The reasons for the failure of the tanker's brakes and how to respond?

In 2021, at around 13:00 local time on November 6, a serious traffic accident occurred on the highway from Mexico City to Puebla, the capital of Mexico. At present, after preliminary investigation, the cause of the incident was that a large oil tanker carrying combustible chemicals had a brake failure and was unable to brake. It hit at least 4 small cars at a highway toll gate, causing a small explosion and fire.

Generally, the brake failure of tank trucks rarely occurs, but there are still some things that cannot be avoided. The brake failure of tank trucks is very dangerous, severely causing explosions, and the scope of the accident is large. What should I do if the tank truck brake fails?

What are the reasons for the failure of the tanker's brakes?

Mainly because of severe overload, inertia caused by emergency brake test under gravity, which directly caused brake failure.

2. Usually lack of awareness of brake maintenance, it is necessary to regularly check whether the brake fluid is too dirty or leaking.

3. Improper driving operations in normal times, such as long-term braking when going downhill or in neutral, have caused brake failure for a long time.

But how to respond when the brakes fail?

1. Control the direction of the oil truck according to the road conditions and vehicle speed, disengage the high speed, quickly step on the empty oil, and switch the high gear to the low gear. At the same time of switching resistance, it should be combined with the handbrake. But the handbrake cannot be pulled too tightly or pulled too slowly, otherwise it will easily "lock" the brake disc, which may damage the transmission parts of the tanker and lose its braking ability; if it is pulled too slowly, it will The brake disc of the tanker is worn and ablated and loses its braking effect.

2. Use warning lights and horns to prompt the vehicle in front to give way in time, and use the bumper and other rigid parts of the vehicle to friction and collide with the roadside natural tree, soil slope or rock to slow the vehicle.

3. When the tanker truck fails to brake when going uphill, it should be reduced to medium and low gears in good time to keep enough power to drive uphill to stop. If you need to stop at half a slope, you should keep the forward low gear, tighten the hand brake, and block the wheels with stones, skids, etc. in time. If there is a back-sliding 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 of the front and rear tank trucks.

Tank truck brake failure is very dangerous, you should pay attention to it, drive correctly at ordinary times, maintain a good speed, and do not overload. Regularly check whether the brakes are in good condition. Try not to step on the sudden brakes as much as possible. Tap the brakes.
