ABSTRACT:
In a brake for an electric motor, stepped helical coiled separator springs (302, 304, 306, 308, 310, 312) urge separation of pressure plates (36, 36a) and friction discs (26, 26a) in the released position of the brake, to reduce brake drag. Each separator spring is an integrally continuously coiled spring (312) having an open coil section (314) extending axially from an abutment surface (336) of the pressure plate (36a). Each separator spring has a closed coil section (318) meeting the open coil section (314) at a step transition (338) in diameter at the pressure plate abutment surface (336) and extending through an aperture (330) in the pressure plate (36a) in the opposite axial direction and press-fit therein.
