Begin by removing the master cylinder cap and fill the reservoir to three quarters full with DOT-3 brake fluid. DO NOT allow brake fluid to contact painted surfaces since it will damage the finish. Wipe up any spills immediately and wash the area with water.

If you choose to manually bleed the system, an assistant makes the job easier. Manually pull the actuator out to fully extended position. Loosen the four bolts on the breakaway lever. Remove the back two bolts, rotate the two breakaway locks to the side and tighten the front two bolts. Pull the lever forward until nearly vertical and return normal operating position. Repeat this stroking action until the air stops bubbling inside the master cylinder. This pumps brake fluid into the trailer braking system.

When the air bubbling stops inside the master cylinder, install a bleeder hose on the bleeder screw of the first
wheel cylinder or disc brake caliper to be bled. Be sure to use the bleeder screw on top of the caliper. Start
with the rear axle on tandem axle trailers. Submerge the other end of the hose in a glass container of brake
fluid so that air bubbles can be observed. Open the bleeder screw one turn. Pull the breakaway lever
completely forward or vertical and close the bleeder screw to prevent air from being pulled back into the
system. Air trapped in the brake lines will greatly reduce your braking efficiency. Push the breakaway lever
down to nearly flat position. Repeat this process until no more air bubbles are released with each stroke. Be
sure to close the bleeder screw securely.

Repeat the bleeding operation at each wheel cylinder or caliper. During the bleeding process, replenish the brake fluid so the level does not fall below half full level in the master cylinder reservoir. When bleeding is complete, fill the reservoir to within 3/8” of the top. Install the filler cap securely. To reset the breakaway lever, loosen the front two bolts. Position the breakaway lever and rotate the two breakaway locks to their original operating or ready position. Install the two rear bolts and lock washers and tighten all four bolts to 90-120 inch pounds of torque.

The brake can be vacuum bled, and the exact procedure will depend on which bleeder you use. There are many videos on YouTube that would walk you through the process.
