ABSTRACT:
A drum brake device is provided in which a single shoe extension device activated by the service brake can yield a braking force equivalent to that of a two leading (2L) type of drum brake device, and which facilitates the incorporation of a parking brake device and an automatic shoe clearance adjustment device. A link (10) is pivoted on an anchor pin (2), the central segment of the link (10) is engaged with the one brake shoe (4), a shoe clearance adjuster (14) is mounted between the link (10) and the other brake shoe (5) between the other pair of adjacent ends of the two brake shoes, wherein braking force can be mutually transferred between the two brake shoes (4, 5) by means of the link (10) and the shoe clearance adjuster (14).
