ABSTRACT A brake for a rotatable shaft is disclosed. The shaft has an end extending outside of a housing. The end is adapted to carry a disk generally perpendicular to the shaft. The housing has a mounting surface facing the disk. A base is securely affixed to the mounting surface of the housing and two support members are secured to the base and extend from the base past the disk generally parallel to the shaft. An inner pressure pad is positioned on the support members adjacent to the base interposed in between the base and the disk and generally parallel to the disk. An outer pressure pad is positioned on the support members with the disk interposed in between the inner pressure pad and the outer pressure pad, and the outer pressure pad is generally parallel to the disk. Springs are inserted on the support members and interposed in between the inner pressure pad and the outer pressure pad to urge the outer pressure pad away from the disk. A lever, having a side facing the disk and another side opposite from the disk, is pivotally mounted on the support members at a distance away from the outer pressure pad, and normally extends generally parallel to the outer pressure pad. Adjusting means are secured to the lever with one end extending to normally contact the outer pressure pad. A frame member is secured to the support members and to the mounting surface, at a position opposite the support members relative to the shaft, to partially enclose the lever and the disk. The frame member has a fulcrum formed thereon protruding from the frame member to contact the lever on the side opposite from the disk. A solenoid is supported by the frame member, and has an armature pivotally attached directly to the lever at a distance Y from the fulcrum. A second spring is connected to the frame member at one end and at another end to the lever, at a distance Z from the fulcrum which is at least equal to the distance Y.
