Mico's 520 Series hydraulic apply caliper disc brake for on- and off-highway service braking applications uses a modulated hydraulic pressure source, such as a master cylinder, to control brake torque. The brake can be mounted in a vertical or horizontal position, and linings can be replaced without removing the brake. The 520 Series includes 2 ductile iron caliper halves that are pressurized by a single inlet port cross-over tube feature which allows hydraulic pressure to actuate the 2.25” diameter piston in each half. The unit provides for continuous duty pressure of 1,000 psi and intermittent duty pressure of 1,500 psi. Weighing approximately 17 lbs, the brake requires a minimum disc diameter of 15”.
