ABSTRACT:
A disc brake arrangement, especially for heavy duty applications in which a pair of brake arms having brake members on the sides facing each other are pivotally supported at one end and spring biased toward each other at the other end. The brake members are adapted to receive the periphery of a brake disc therebetween. A disengaging device is provided which includes a lever pivoted to the free ends of the arms and having a wedge shaped nose which will press the arms apart when the lever is pivoted in one direction and which will cam out between the arms when the lever is released. The brake members are adjustably mounted on the respective arms and each brake member support includes an adjustment, with each adjustment being provided with a free wheeling one way clutch device. A lost motion linkage connects each free wheeling device with the disengaging lever for actuation of the pertaining adjustment in a direction to move the brake members toward each other whenever the movement of the lever between brake disengaging and brake engaged positions exceeds a predetermined amount.
