INSTRUCTIONS FOR 10" BRAKES BRAKE INSTALLATION When the brakes have been correctly assembled to the axle flanges, the hub and drum assemblies may be mounted on the axle spindle. 1. Brake Mounting Flange To assure correct brake action, the mounting flange must be square and concentric with the axle spindle. A flange that is not properly installed will contribute to rapid lining wear and improper brake action. Two types of hubs may be used.
WARNING: To Prevent Serious Injury or Death Saltwater, granular fertilizers and other corrosive materials are destructive to metal. To prolong the life of a braking system used under corrosive conditions, we recommend that the actuator be flushed periodically with a high pressure water hose. Be sure to re-grease bearings and oil all moving parts after the unit has dried. At the end of the season, when unit is to be stored, remove the brake drums and clean inside the brakes.
