Abstract

An internal shoe brake (13) has a substantially circular brake shoe (14) mounted on a support (20, 23) and having a mechanical actuator (17) located between a pair of opposed ends (15, 16) of the shoe for moving the brake shoe ends apart to apply the brake. The actuator takes the form of a first lever (31) pivotted at one end (32) on the support (23, 33) and connected at its other end (35) with a brake operating means such as a cable (24). The one end (32) of the first lever contacts one shoe end (16) and a second lever (41) is pivotted on the first lever. The second lever is operatively connected with the other shoe end (15) via a brake shoe clearance adjuster means (50). The brake shoe clearance adjuster means may be manually operated or may be automatic. <IMAGE>
