16t BPW axle use 200mm width brake shoe assembly for repair

The material of brake pads depends on the braking performance and stability. Some new drivers have good trailer braking performance. After replacing the brake pads, the brake immediately decreases (that is, the original bridge, not the assembled bridge). That's the factor. The friction coefficient and heat recession are the most important factors. The friction coefficient of ordinary brake pads can't meet the braking requirements, so the braking performance is not ideal Frequent braking on special roads in plateau or mountainous areas will cause the temperature to rise and the friction coefficient to decrease from 180 ℃ to 220 ℃. Therefore, the critical temperature of heat recession is very important. The obvious feeling is that the brake foot is soft, and the braking effect is not obvious.

Different brake pads have different heat decay temperatures. For the time being, the temperature of poor brake pads is generally 170 ℃ - 200 ℃, while that of good brake pads is at least 200-280 ℃. You can imagine which one is safer.

If the high temperature brake performance is reduced or the brake fails, similar events often occur, because the braking performance is not good. The brake pad material can not meet the requirements of high temperature of braking, which leads to the occurrence of accidents. The friction coefficient of good brake pad itself is 0.38-0.40, and the friction coefficient of 230-290 ℃ will not be reduced, and the brake drum will not be hurt. The service life is about twice as long as that of ordinary brake pads.

Some repair factories don't know the brake pads deeply, they are basically ordinary brake pads. Of course, there are some driver friends' psychological existence of saving maintenance costs. In fact, this is a mistake in itself Instead of saving maintenance costs, you have increased the maintenance costs. The service life of the poor brake pads is short and the brake drum is particularly damaged. The brake drums are replaced one after another in 1-2 years. Think about how much it is? It is suggested that the brake pads which meet the national standards can ensure the stability of braking performance and improve the service life.

Some friends think that just changing the brake valve can improve the braking performance of the whole vehicle, but it's not right. The modification of the brake system, that is, the upgrade of the brake valve, is an indispensable part of the whole brake system. However, if you drive on special roads in plateau or mountainous areas, you can't control the friction coefficient of the brake pads by changing the brake valve. In other words, you can't control the high temperature of the brake pads when you brake frequently. Of course, good braking performance will reduce the temperature of the brake drum, which can be reduced by one or two feet To the desired safe speed, if the braking performance is not ideal, you need to step on more feet, each step on two feet, so that the pressure drops by 0.1MPa or more. The more times you step on, the more air pressure you consume, the more you can't brake, the higher the temperature of the brake pad, the lower the friction coefficient. It's a vicious circle. The brake valve with superior performance and the special brake pad with good material are complementary, and both are indispensable.
