MADE IN U.S.A PAGE 1PUBLICATION NO. 172280210DESCRIPTION OF OPERATIONOn this brake, the magnet coil is a separately enclosed unit mounted between an inner and outer armature. When the coil isproperly energized, the armatures are attracted to each other until their outer poles seal. The action of the armatures moves theshoes away from the wheel. The inner armature moves the inner shoe and the outer armature moves the outer shoe. When thecoil is de-energized, the compression spring forces the armatures apart and presses the shoes against the wheel.PROCEDURE FOR INSTALLATION AND OPERATION(Refer To Dimension Drawing For Mounting Dimensions)1.
