  • Patent number: 4842102
    Abstract: A disc brake includes two pad supporting levers which are pivotally mounted on a single pivot. One of the levers has a first adjustment bolt which abuts the other lever to control the maximum clearance between the pads and a second which abuts the bracket on which the levers are pivotally mounted to control the clearance between one of the pads and the rotatable disc. A linkage which interconnects the levers induces same to rotate and clamp the pads against the rotatable disc by (a) a foot pedal controlled hydraulic servo integrated with the bracket and/or (b) a cable arrangement operatively connected with a hand brake.
