Product Bulletin Brake Actuators for OEM Drive Axles MICO® Hydraulic Brake Actuators are designed for direct installation on CNH off-highway, heavy-duty drive axles. CNH drive axles contain internal brakes that are operated by means of integral mechanical pull-rods. The MICO® Hydraulic Brake Actuators install directly onto the pull-rods to provide hydraulic control to apply and release the axle brakes. MICO® Spring Apply and Spring Apply/Hydraulic Apply Actuators are designed for use with CNH D-45, D-60 and D-62 series drive axles. For other CNH series drive axles contact MICO. The spring apply actuators are a spring apply, hydraulic release actuator to be used for parking brakes. The spring apply/hydraulic apply actuators can be used for parking brakes and service braking. All MICO® Brake Actuators are designed for use with mineral base hydraulic oil. TYPICAL SYSTEM Designed for use with CNH D-45, D-60, D-62 series axles Can be installed with little or no modification to the original axle Totally enclosed units make them ideal for use in adverse environmental conditions Provide service and parking brakes or parking brakes only depending on the model selected TYPICAL INSTALLATION MICO Brake Actuators Pull rod
