Service Brake Provides Continuous Pressure
Mico’s new 520 Series hydraulic, fixed
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. It
can be mounted in a vertical or horizontal
position and linings can be replaced without
removing the brake. The brake includes
two 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-in.-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 lb, the brake
requires a minimum disc diameter of 15
in. To reduce unnecessary lining wear, the
brake features a spring-operated lining
retractor mechanism that maintains a constant
lining-to-rotor disc clearance distance
whenever the brake is not applied.
The total lining contact area is 12.4 in.2,
with a usable lining thickness of 0.32 in.
on each side. Linings can be replaced without
disassembling or removing the brake,
allowing for reduced maintenance time
and costs. The unit can be attached directly
to a threaded hanger or clamp.
