摘要： A disc brake having one or multiple axially movable rotor discs (52, 54) with annular friction surfaces disposed axially between an annular piston (31) in an annular pressure cavity (26) formed in a housing (22) and annular reaction plate attached to the piston. Friction pads are provided on the reaction plate and also on an axially movable annular reaction disc disposed between the rotor discs. A positioning plate (80) is disposed between the piston and rotor discs and has axially movable poppets (92) thereon, each with a friction pad for contacting the adjacent rotor disc. Individual springs on each poppet bias the poppet pads, rotor discs and friction pads axially together to provide a desired initial braking torque. Upon fluid pressure applied in the piston cavity, the housing moves the positioning plate to move the poppets to release braking torque.
