Abstract
An automatic brake lever (1) with a built-in slack adjuster is intended for transmitting brake force from a brake cylinder and is mounted on a brake actuating cam shaft (2). For the purpose of accomplishing a wear indicating device, a coded disc (10) is connected to the cam shaft, whereas a housing (9, 11) therefore is connected to the brake lever or a fix-point for the lever. The coded disc is provided with a number of coded paths of circular shape, magnetic areas of equal length being provided in each coded path. A number of hall-elements (15) corresponding to the number of coded paths are provided in the cover (11) of the housing, each hall-element being arranged to sense the magnetic areas in the respective coded path. The signals from the hall-elements together indicate the relative position between the disc and the cover.
