A wheel cylinder is provided between lever portions of a pair of seesaw-shaped levers rearward of the anchor pin of a pair of seesaw-shaped levers extending opposite to each other, the wheel cylinder being pivotally connected to the anchor pin. In a rear actuation mechanism of a scissor-type disc brake that engages respective ends of the pair of rear lever parts and an operating end of a piston of the wheel cylinder, the respective ends of the pair of rear lever parts are engaged with each other. A new actuation mechanism is adopted for the engagement between the wheel cylinder and the working end of the piston of the wheel cylinder.

供するものである。 The rear operating mechanism of the scissor-type disc brake of the present invention is constructed as described above, and when the wheel cylinder 20 is operated to push out the piston 29, the rear operating mechanism is operated via the operating pin 28, bracket 26, and angle bracket 27. Lever part 22b, 2
Expand each end of 2'b. At the same time, friction pads 31, 31' set on the inner ends of the front lever parts 22a, 22'a clamp and brake the rotating rotor outer peripheral part 24a. When parking a vehicle, etc., operate the parking lever, pull the parking cable 30, and expand the respective ends of the rear lever portions 22b and 22'b via the bracket 26 and the angle bracket 27, as described above. Brake the rotor in the same way,
The parking lever is not operated when the hydraulic pressure is activated, and the hydraulic cylinder is not operated when the parking lever is operated to prevent negative pressure air from getting caught.However, when the friction pad is worn out, the parking cable can be operated. Therefore, the present invention provides an extremely useful and novel rear actuating mechanism for a scissors-type disc brake, which is capable of adjusting the gap between the rotor and the friction pad.
