Abstract
A rear brake device for a beach buggy includes an axle sleeve, a brake disc fixed at one side of the axle sleeve and having two semicircular brake members, and a brake drum with a center serrated tube to engage and rotate synchronously with the axle. The brake disc and the brake drum are made of aluminum of high strength, and the axle sleeve is fixed at the other side of the brake disc, and the brake drum covers an outer side of the brake members. The axle fits in a cylindrical fix tube to force the brake drum firmly touch the brake disc without falling off and sealing the serrated connect tube, too. A dirt rubber ring is fitted around the joining location of the brake drum and the brake disc. Then the brake disc does not disfigure, and the brake drum can increase its size and functions as a cover so as to increase the friction coefficient to enhance braking effect.
