1. The brakes are very hot and the water is entering the pool

Many downhill sections of highways will design a cooling pool halfway up the mountain to lower the temperature of the brake drum. If the temperature of the brake drum is too high, entering the water tank directly can easily cause cracks, and in severe cases, even explosions.

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


2. Only start pouring water when the temperature is too high

Brake water spray is an important device for ensuring the safety of domestic trucks, mainly used to reduce the temperature of the brake drum and minimize the thermal degradation of the brakes. If the brake drum is too hot and water is sprayed, it will only cause the brake drum to crack.

Suggestion: Before going downhill, it is best to choose to keep the water running for a long time. It won't cost much, but it can improve driving safety.

The brake water spray device has always been a very contradictory thing in China. In the north, you can install it, but he said you can modify it. In the south, you can't install it. He also said you violated the rules, which is embarrassing and painful. Only truck drivers know that kind of smell.

Suggestion: It is best to choose vehicles with auxiliary braking, operate them correctly, and reduce unnecessary braking when going downhill.


3. Change to "Brake King"

The brake is not easy to use, usually due to many reasons. Some drivers choose a product called "Brake King" to improve braking efficiency. The so-called "good braking" of the brake king is nothing more than increasing the amount of air in the brake air path, resulting in the brake drum not being able to withstand such a large force, leading to rupture.

Suggestion: Poor braking is usually a system problem. It is best to systematically check the air circuit, valve body, and mechanical parts. It is best not to use the brake king.


4. Over reliance on trailer braking

In order to prevent the phenomenon of "pushing the head" on wet and slippery roads, some semi-trailer tractors in China weaken the braking of the main vehicle and rely too much on the braking of the trailer, resulting in excessive load on the trailer brake drum and a high failure rate.

Suggestion: Pay attention to checking the braking of the entire vehicle, maintain overall coordination between the main vehicle and trailer braking, and do not rely too much on trailer braking.


5. Not paying attention to regular inspections

Some careless drivers usually do not pay attention to the condition of their brake drums. When maintaining the car, they should pay more attention to observing the thickness of the brake drums and whether there are too serious cracks.

Suggestion: Trucks should be maintained instead of repaired. Pay attention to inspections and do not wait until they are broken before repairing.
