Abstract
In a disc brake of the spreading type an automatic adjuster is located within the housing of the brake. The adjuster comprises an extensible strut which acts between radial lugs on pressure plates to maintain the pressure plates in relative angular positions in which the braking clearances are maintained within the predetermined limits. In the construction described the strut is coupled at each end to a respective plate through a lever which is urged into a neutral position by a spring. The load in the spring is chosen to permit the lever to move angularly about a pivotal connection with its respective plate and prevent the effective length of the strut from being increased further as a result of loads which are transmitted through the strut as a consequence of structural deflection of the housing. The adjuster is therefore said to be 'load-insensitive' for both directions of disc rotation.
