ABSTRACT:
A negative disc brake comprising a cylinder assembly having a thrusting mechanism wherein a thrusting force of an actuating spring is normally transmitted to a thrusting piston through an actuating piston and an adjustment screw which is in screwed engagement with the actuating piston; the thrusting piston normally pushes one friction pad against a rotor; however, when a fluid pressure is applied, the actuating piston moves against the thrusting force of the actuating spring in the direction of taking off the brake; and a caliper assembly having a reaction member which pushes another friction pad against the opposite side of the rotor by a reaction force resulting from the thrusting force exerted on the other friction pad to push it against the rotor in the brake applying action of the thrusting mechanism, the caliper assembly and the cylinder assembly being arranged as independent components mountable and dismountable separately from each other.
