The Hilliard Corporation and Twiflex Ltd. have applied over 70 years of combined experience to develop a new range of spring applied electrically released caliper disc brakes. The design incorporates the MXand SMX caliper, a well proven industry standard utilizing electromagnetic technology for the actuator developed by Hilliard. 

General Description
The MX SE and SMX SE series of spring applied and electrically released calipers are designed for medium to heavy emergency stopping and holding applications. The calipers can be used with standard brake discs or clamped to the guide rail of existing equipment. Normally one or two units can be used per disc, but the number may be increased depending on the disc size and brake torque requirement.
