Abstract

A brake has a pair of brake pads (12) , each pad being moveable generally radially outwardly into contact with a brake drum by a respective operating lever (14) acted on at one end by a brake applying means (15) and pivoted (16) at the other end from a backplate (11) . Each pad is contacted by a portion (14c) of the respective operating lever intermediate the lever ends and moving radially outwardly between a pair of circumf erentially spaced abutments (45) which extend generally perpendicular to the backplate and which react braking torque when the brake is -applied. Each lever (14) is pivoted on the backplate (11) by a pin (16) which extends generally perpendicular to the backplate. The free ends of the pins (14) are connected by a bracing link (50) to help to control the deflection of the pins (16) when the brake is applied.
