Abstract

PURPOSE: To allow a simple structure to perform a functioning of a drum brake, by locating a parking brake system, whidh functions throughly mechanically, and a wheel cylinder so that the two parts will work in a given relation.
CONSTITUTION: A parking brake system 19, which enlarges fully mechanically a distance between the end parts of two shoes 4 and 5, is located near a place where the end parts of the two shoes 4 and 5 are contact with an anchor 3. Meanwhile a wheel cylinder 6, which is situated between the other end parts of the shoes 4 and 5, enlarges a distance between the other end parts of the shoes when a braking liuid pressure is applied. Furthermore, the device is constituted in such a manner as can rigidly couple together the other end parts when the system 19 is operated, and also permits the other end parts to move in the rotating dirdction of a brake drum 1. That is, a normal braking is performed by feeding the brake liquid into the cyliner 6, and the operation of the system 19 can result in obtaining a large braking force for parking by the use of a relatively small operating force.
