1. It is found that the brake drum temperature is too high before pouring water

Brake drench is an important device to ensure the safety of domestic cars, mainly used to reduce the temperature of the brake drum, reduce the thermal recession of the brake. If the brake drum is too hot, it is more likely to lead to brake drum cracking.

Suggestion: before the refrigerator car downhill, it is best to choose long dousing water, spend a few money but can improve the safety of driving.

2. The brake is very hot and enters the pool

In many high-speed downhill sections, a pool of water designed to cool down the hillside lowers the temperature of the brake drum. If the brake drum temperature is too high, it directly into the pool, it is easy to cause cracks, serious may also burst.

Suggestion: If the temperature of the brake drum is too high, you need to stop for a rest and let it cool down naturally.

3, some cars changed to "brake king"

Brakes don't work well for many reasons. Some drivers choose a product called "Brake King" to improve their braking. "Good braking" is nothing more than to increase the amount of air on the brake air, which can lead to a rupture, because the brake drum can not withstand that much force.

Suggestion: Poor braking is a system problem, to check the system of air, valve body and mechanical parts, do not use what "brake king".

4. Over-reliance on trailer braking

In order to prevent the phenomenon of "pushing head" on wet roads, many refrigerated vehicles in China weaken the braking of the main vehicle, and then excessively rely on the trailer braking, resulting in excessive load of the trailer brake drum and high failure rate.

Suggestion: pay attention to check the whole vehicle brake, keep the overall coordination between the main vehicle and the trailer, do not rely too much on the trailer brake.

5. Do not pay attention to daily inspection

Some careless drivers usually do not pay attention to their brake drum situation. In peacetime maintenance of the car type, we should pay more attention to observe the thickness of the brake drum, see if there are too serious cracks and so on.
