Water Wading May Cause Garbage Trucks Failure

We know that garbage trucks rely on the brakes and the brake drum brake friction between the fierce done. Moving in the water, the wheel almost submerged in water, makes brake pads and left a layer of water film between the brake drum, a layer of oil coated the same as that between the brake pads and brake drums become very smooth and reduce the friction, can not control the garbage truck stopped, and the drum, the water is not easily shed.

 

This phenomenon of brake failure came very fast, the wheel immersed in water occurred. Therefore, we must have brakes before wading psychologically prepared, walked away from the water hit the brakes, that is the right foot stepped on the accelerator, left foot brake. Continuous step several times, between the brake pads and brake drum of water droplets will be erased at the same time, the friction heat generated by its drying so that the brake quickly to restore the original sensitivity.

This phenomenon of brake failure disc brake system for vehicles using it almost does not occur, because the drum brake is the resistance obtained by the braking effect of friction, while the disc brake system, brake very small, disc All the exposed peripheral and, unable to retain water droplets. Thus, as the wheel rotates the centrifugal force, water droplets on the disc will automatically lost, does not affect the function of the brake system. We normally use in garbage trucks, small cars are mostly front wheel with disc brakes, rear drum brakes with, so after wading, some brakes, some brakes will diminish a lot.

Brake drum water to make the case a lot of brake failure, is not limited to wading, such as car washing, we used to wash cars with water cannons, this effort quickly, which can easily cause the brake drum of water. Re steam car wash with some people, causing the original drop of water has also been easy to place into the hot vapor into liquid water solidified soon after, so natural to brake failure. These tell us that take this approach if the car wash, it is estimated garbage truck brake drum into the water, start the car when on the road, the brakes must be multi-step kicks, and a habit, try the brakes not working spirit, so in a timely manner to ways to solve them. Otherwise, driving a car at high speed, encountered when dealing with the situation, only to discover garbage truck did not brake very dangerous.
