No. 12, A3, gucheng industrial park, longyao county, xingtai city, hebei province.Five causes of brake drum cracking
1. The brakes are hot. Go into the pool
Many high-speed downhill sections will design a cooling pool halfway up the hill to lower the temperature of the brake drum. if
The temperature of the brake drum is too high, and it is easy to cause cracks or even burst when entering the pool directly.
Suggestion: If the brake drum gets too hot, stop for a rest and let it cool naturally.
2. It is found that the temperature is high before pouring water brake is an important device to ensure the safety of domestic trucks, the main role is to reduce the temperature of the brake drum, reduce the thermal recession of the brake. And if the brake drum is too hot when the water, only let the brake drum cracking consequences.
Suggestion: before going downhill, it is recommended to choose long dousing water, which does not spend much money, but can improve driving safety.
Brake drench device, in China has been a very contradictory thing, in the north you install it, he said you modify, run to the south you
Don't pack it, he said you violated the rules, which embarrassed and suffering, only truck people know that kind of taste. Recommend or choose
Vehicles with auxiliary braking, correct operation, reduce unnecessary braking when downhill.
3. Change to "Brake King."
Brakes don't work well for many reasons. In order to improve the braking effect, some drivers choose a type called "brake king"
". The so-called "good braking" of the brake king is nothing more than to increase the excess gas on the brake gas road, the result is that the brake drum can not withstand so much force, resulting in rupture.
Suggestion: Poor braking is usually a system problem. Check the air path, valve body and mechanical part of the system
Use the brake king.
4. Over-reliance on trailer braking
In order to prevent the phenomenon of "pushing head" on wet road surface, some semitrailer tractors in China weaken the braking of the main car and rely too much on it
Trailer brake, resulting in trailer brake drum overload, resulting in high failure rate.
Suggestion: pay attention to check the whole vehicle brake, keep the overall coordination of the main vehicle and trailer brake, do not rely too much on trailer brake.
5. Usually do not pay attention to check, some careless drivers usually will not pay attention to their brake drum situation in the end is what, usually maintenance of the car, should pay more attention to observe the thickness of the brake drum, whether there are too serious cracks, etc..
