Abstract

In a spot-type disc brake having a hydraulic actuator 11 for service braking and a mechanical actuator 10 for parking purposes and in which pads 6, 7 are guided and supported in a circumferential direction in a fixed carrier frame or torque plate assembly 74, 74 there is provided a pincer-like bell-crank lever assembly 8 having two power transmission arms 81, 82 pivotable about a common pivot 9 and two actuating arms 83, 84, respectively integral with said arms 81, 82. Assembly 8 is pivotally mounted to said carrier frame by the free end actuating arm 84 such that the free ends of the arms 81, 82 respectively act upon pads 6, 7 to press the latter against the brake disc 3 upon actuation, and in which mechanical actuator 10 on a hydraulic actuator 11 both act upon the other actuating arm 83 of assembly 8, the hydraulic actuator 11 being secured to the carrier frame and being aligned that its line of action extends parallel to the brake disc 3 and through the pivotal mounting point 12 at which said arm 84 is pivoted to said frame. <IMAGE>
