When pulling the trailer forward and the actuator extends, the brake lockout should fallout of the slot. This ensures that the actuator will function when stopping.The brake lockout bracket must be removedbefore towing or the trailer brakeswill not work.Manual bleeding of brakesCheck that all hydraulic fittings are secure.Read and understand all instructions before starting.Two people are required for manual bleeding.1. Remove the master cylinder reservoir plugand fill the reservoir with brake fluid. Use eitherDOT 3 (preferred) or DOT 4 automotivebrake fluid. Follow the instructions on the brakefluid container. Avoid shaking the brake fluidcontainer and pour fluid slowly to minimize airentrapment. Let the fluid in the reservoir standuntil it is completely free of air bubbles.2. IMPORTANT: Before bleeding the brakelines, bleed the actuator master cylinder. Inserta screwdriver through the hole in thebottom of the inner member and use shortstrokes to pry on the push rod (while holdingthe safety release bracket up) until no airbubbles are seen coming from the small orificehole in the bottom of the master cylinderreservoir.3. Start the bleeding procedure on the brakefarthest from the master cylinder.4. At the brake assembly, connect a transparentbleeder hose to the bleed screw fittingon the wheel cylinder and submerge the freeend into a container partially filled with brakefluid. Do not reuse this fluid.5. The first person should stroke the push rodslowly while holding the safety release bracketup. The second person opens the bleedscrew fitting. He then closes the bleed screwfitting BEFORE the first person SLOWLY releasesthe push rod. Repeat this procedureuntil the fluid expelled from the bleeder hoseis free of air bubbles. Remember to alwaysThe following procedure should be performedonly by skilled mechanics. Master-Craft recommends that it be completed byan authorized MasterCraft dealer.MasterCraft Trailer Manual • Page 17
tighten the bleeder screw before releasing the push rod. During this procedure, themaster cylinder reservoir fluid level must be maintained at no less than half full.6. Repeat Steps 4 and 5 for the other brake, as well as the brakes on the front axle oftandem axles.7. If installation is on a tandem-axle trailer, repeat the bleeding procedure on the rear axlebrakes for a second time to assure purging of all air in the system.8. As a final check after bleeding is completed, stroke the push rod and check to be surethe brake system is pressurized. This is done by attempting to rotate a tire around.9. Push up on the safety release bracket to ensure that the push rod is in the releasedposition.10. After the bleeding is completed, recheck the fluid level in the master cylinder. Fill themaster cylinder reservoir to the indicator on the reservoir plug. Do not overfill.Important: Do not use brake fluid drainedfrom the brake system to refill the mastercylinder reservoir as such fluids containcontaminants from the system that mayresult in brake failure or costly repairs.Trailer JackMasterCraft recommends using the trailer jack tolift the coupling of a loaded trailer from the hitch ball,and for moving the trailer about when it is disconnectedfrom the towing vehicle. Rotate the trailer jack tothe vertical position and engage the locking pin beforeplacing a load on the trailer jack.Like any mechanical assembly, the trailer jack requiresmaintenance to continue functioning properly.The drive gear and the rack-and-pinion should begreased, and the coaster and wheel bearings shouldbe oiled frequently.Failure to swing up the trailer jack before towingmay result in damage to the trailer.Failure to engage the locking pin may resultin the collapse of the jack stand, whichcould cause serious injury or death.tie-Downsensuring that a MasterCraft boat will be held securely in place on the trailer’s hull support,especially when underway, is extremely important. If the boat is not firmly and properlysecured, the boat can be damaged as it bounces against the hull supports.MasterCraft’s Boat Buddy System is located on the winch stand. Ask an authorizedMasterCraft dealer to demonstrate the proper use of the Boat Buddy System. A separatewinch strap is provided and should be attached to secure the boat to the bow strap.MasterCraft Trailer Manual • Page 18
