In the course of driving, if the brakes fail, it is a very dangerous thing, so check the brake system regularly (the brake drum, the brake disc, the brake disc, etc.). Why do the brakes fail? There are three reasons:
    The first is the lack of necessary maintenance for the brake system, too much impurities in the brake pump, tight seal, vacuum pump failure, brake oil dirty or several kinds of brake oil mixed use of heat after the use of gas resistance, brake general pump or sub pump oil leakage, gas tank or pipeline interface leakage;
    The two is due to improper operation resulting in parts failure, such as prolonged downhill will cause brake disc friction heating, brake hub carbonization, brake function completely failure.
    Three, due to serious overload, under the action of acceleration of gravity, the inertia of vehicle is increased, resulting in the brake failure.

    Brake failure is a very dangerous thing. You must always check the brake system (brake drum, brake disc, brake disc, etc.) in your daily life.
