CALIPER DISC BRAKES MICO® Caliper Disc Brakes are either a floating or fixed design. Models are available for use with both brake fluid and mineral base hydraulic oil. MICO® Caliper Disc Brakes are ideal for providing primary, emergency, and secondary braking for applications in the agriculture, construction, mining, airport support, and forestry industries. 515 SERIES CALIPERS are a floating type design. They mount over a rotor disc using either pins or shoulder bolts. One side of the caliper is actuated to provide clamping force. Spring Apply Caliper Disc Brakes 515 Series Floating design....

MULTIPLE DISC BRAKES MICO® Multiple Disc Brakes are fully enclosed units that use coil springs and multiple friction discs to produce braking torque. These brakes are applied by coil springs and released using hydraulic pressure. Maximum brake torque is achieved when hydraulic release pressure is zero. These brakes are self-applying in that any function which reduces hydraulic release pressure will begin to initiate brake clamping force. Large diameter spline shaft virtually eliminates spline battering. Low release pressures make these brakes ideal for use with closed loop hydrostatic systems....

BRAKE ACTUATION MASTER CYLINDERS MICO® Master Cylinders are single piston, straight-bore type with a return spring, and are available with or without an integral reservoir. Most cylinders are available as brake fluid or mineral base hydraulic oil models and in a variety of mounting styles. MICO® Two-stage Master Cylinders are integrally designed to incorporate the advantage of a large piston for fluid volume and a small piston for high pressure. Transfer from the volume piston to the pressure piston is accomplished by means of a metered pressure relief valve. Two-stage Master Cylinders are commonly...

BRAKE ACTUATION SLAVE AND WHEEL CYLINDERS MICO® Hydraulic Slave Cylinders and Wheel Cylinders are small bore, short stroke cylinders used for remote clutch and brake actuation. They are available in a variety of strokes, mountings, and bores. Most cylinders are available as brake fluid or mineral base hydraulic oil models. These cylinders are used in industrial applications for holding, clamping, and latching. They are also used in off-highway applications. Two-stage Master Cylinders Bore diameters for these cylinders are 1.75 inch over 1 inch or 1.75 inch over 1.125 inch. Effective stroke is...

BRAKE ACTUATION TWO FLUID ACTUATORS The MICO® Two Fluid Actuators combine a booster section with a master cylinder section in a single unit. These actuators allow the booster section to use one type of fluid and the master cylinder section another. This feature enables the booster section to be powered by an existing mineral base hydraulic oil circuit while maintaining use of DOT brake fluid in the rest of the system. With the same pedal effort, MICO® Two Fluid Actuators provide higher output pressure than non-boosted master cylinders. Boosted Straight Bore Master Cylinders Can develop brake...

BRAKE ACTUATION AIR/HYDRAULIC ACTUATORS MICO® Air/Hydraulic Actuators combine a large surface area air chamber with a smaller diameter bore master cylinder or actuator. They allow the use of a pressurized air source to produce high hydraulic pressure. Air/hydraulic actuators can be used on a variety of vehicles and industrial applications within the construction, material handling, mining, forestry, and agriculture markets. Unique application: A towed vehicle that is hydraulically braked and equipped with an air/hydraulic actuator can utilize the air-actuated brakes of the vehicle that is towing...

BRAKE ACTUATION REMOTE ACTUATORS MICO® Remote Actuators are typically used to actuate a brake or clutch from two locations when two master cylinders are used. They prevent the transfer of fluid from one system to another system. These actuators are available in hand, foot, or hydraulically operated models. They can be used in combination with a remote reservoir to accommodate accessibility. Pressure intensifiers are ideal for applications where a low pressure hydraulic source is available and a small displacement of high pressure hydraulic fluid is required. Remote Actuators (hydraulically operated)...

MICO® Brake Locks are to be used in conjunction with a vehicle’s mechanical parking brake. They function as a supplemental brake holding device and are not intended to be used for prolonged parking. All MICO® Brake Locks include a low pressure warning switch. The switch is connected to a visual and audible alarm to alert the operator of an unsafe reduction in locked brake pressure. Several types of brake locks are available for use on single, dual, split, or anti-lock brake systems. Cable Locks 691 Brake Lock Systems These systems lock hydraulic pressure in the service brakes to supplement the...
