1. Drip brake is to install a spray device on the brake. When braking, the device will cool the braking system by spraying water, so as to alleviate the thermal attenuation of the brake, avoid the decline of the mechanical performance of the brake and weaken the braking effect. However, in low temperature weather, the dripping device froze, and it was impossible to drop water to cool the tire, which led to the tire heating and accidents.

Therefore, try not to use drippers in freezing weather. First, it is easy to freeze and block, causing the tire to heat up and catch fire; Second, after the water flows to the road surface, it will cause the road surface to freeze and slip, causing other accidents.
