WATERPROOF DEVICE FOR DRUM BRAKE

摘要

A waterproof device for a drum brake can prevent noise and malfunction of a brake by stopping water from flowing into the drum brake. The waterproof device for a drum brake can minimize not only foreign substances, but also water flowing into a drum, by improving the mounting structure of a dust cover that is mounted at the drum inlet of a drum brake in a new structure that is mounted hermetically and watertightly along the inner edge of a drum by buoyancy or pressure due to water when passing a puddle or a wheel washer.
