The Demco Hydraulic Brake Actuator w/ Drop - Drum - Zinc - 2-5/16" Ball - 20,000 lbs # DM8204011 is rated to be used with brakes on 2 axles, or 4 brakes total. If all 3 of your axles have brakes, you will need to add the Demco Replacement Large Bore Aluminum Master Cylinder w/ Bypass Solenoid - Disc Brakes # DM6113 and Push Rod Assembly for Demco Brake Actuators with 1-1/4" Bore # DM74ZR. These additions will get the needed pressure to actuate all 3 axles.
