The brake of the aluminum alloy hand tip of the gourd is mainly composed of a spine wheel, two friction pieces, and a braking base. In this way, the friction film when the handle brake is made with the spine wheel, which produces huge friction to the brake to achieve the braking. Effect. Secondly, the friction tablets in the aluminum alloy hand pulling the gourd brake are friction tablets. When the gourd is stopped, it can immediately play the braking effect, and it is very sensitive. In addition, although the aluminum alloy hand pulls the gourd, although it is sensitive, we also need to check and maintain it carefully to ensure that its performance is not affected. For example: If the oil droplets are dripped between the friction tablet and the spiny wheels, it will reduce the friction coefficient and reduce the braking performance.
