Abstract
A disc brake or clutch unit (10) comprising a rotor disc (12) having a fixed reaction member (21,23) on each side of the rotor disc (12) with the reaction members fixed in axially spaced relationship by connecting members (24,25) extending axially in position radially outwardly from the rotor disc. A pair of moveable reaction members (27,28) positioned between each side of the rotor disc (12) and one of the second fixed reaction members with the relatively moveable annular reaction members connected to each other a fixed axial distance apart by connecting members (29,30) extending axially and positioned radially outwardly from the rotor disc (12). Springs (35) are positioned between a first axially moveable reaction member (27) and a relatively fixed reaction member (23) for biasing the moveable reaction member (27) into fictional engagement with the disc (12). The fixed reaction member (23) and a moveable reaction member (28) forming an annular pressurized chamber (38) which when pressurized causes the moveable reaction members (28) to move axially away from the rotor discs to compress the springs (35) and disengage the annular axial moveable reaction members (27) from the discs (…
