Creation instructions (2) These dusts will seriously affect the friction coefficient, so some operators will set several ui-shaped grooves 3 2 on the friction surface 3 1 of the brake pad 3 (as shown in the third figure) (Shown) to temporarily store the generated dust, but because the drum brake is a closed brake system, this dust cannot be discharged and will accumulate more, and in the case of long-term use of the brake, it will make the inside of the wheel hub Too high temperature will eventually reduce the friction coefficient and affect the braking effect. [New content] In view of the defects of the above-mentioned conventional drum brake device, the creator felt that it had not been perfected, and exhausted his mind to study and overcome it. Based on his accumulated experience in the industry for many years, he developed a drum brake.
