A constricting clutch brake element (10) is operative to selectively transmit mechanical power between relatively movable rotating members. A plurality of backing plates (38) releasibly engage a plurality of friction linings (34). The friction linings are selectively moved radially to operatively engage annular body (12) and a central rotating member (26). The friction linings are releasibly engaged with corresponding backing plates (38) through interengaging ear portions (52) of the lining and slots (62) of the backing plates.
