Lack of necessary maintenance of the brake system, too much impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, excessively dirty brake fluid, or mixed use of several brake fluids, air resistance occurs after heating, and the brake master cylinder or sub-cylinder leaks oil , Air storage tank or pipeline interface leak; it is due to improper operation that causes mechanical failure; it is due to severe overload, under the action of gravitational acceleration, the inertia of the vehicle movement is increased, which directly causes the brake to fail.
Second. Explosive treatment method of brake pipe:
(1) Preventive measures:
