2023 OWNER’S MANUAL
• Check for foam or bubbles in the brake fluid. If either is present,
drain the fluid from the master cylinder and replace with ONLY
new brake fluid of the same type (DOT 3 is preferred—or DOT
4). DO NOT USE DOT 5 FLUID. (See specific information in
Recommended Brake Fluid in this section of this
Owner’s Manual.)
• In order for brakes to function properly, all air must be expelled
from the brake system. If bleeding is necessary, have an
authorized MasterCraft dealer perform this function or follow
the manual bleeding of the brake system instructions as
outlined in this Owner’s Manual. It is imperative that the system
be filled with only ONE type of brake fluid. Different types do not
mix. Follow the instructions on the brake fluid container.
• Check the safety chains and attachment points for damage or
wear. Repair or replace as necessary.
• Check the breakaway cable for worn or frayed cable strands.
End fittings should be checked for damage.
Replace as necessary.
• Check for any hydraulic leaks in the brake system. Be sure all
tube fittings are tight. Periodic checks must be made on all
hoses, brake line tubing and fittings to guard against cuts, worn
hoses and loose fittings that may cause leaks in the trailer
brake hydraulic system. Replace deteriorated and damaged
parts as necessary.
• Check for chips and nicks in the paint. Touch up as necessary.
Ignoring this will lead to accelerated wear and deterioration of
the trailer.
• Check the condition of the bunks. If the coverings show wear,
discuss with an authorized MasterCraft dealer. If the coverings
Annually Or Every 2,000 Miles, Whichever
Occurs First (In Addition To The Above)
• To assure the bearings are in good working order, check the
bearing adjustment at least once a year by following this
procedure: Jack up one side of the trailer. (Be certain to use
jack stands and chock the trailer wheels to keep the trailer from
moving during the inspection.) Grip the edge of the tire and see
if it can be rocked or moved. If the outer edge of the tire moves
more than 1/8” at all, the bearings may need to be readjusted.
• Inspect the tow hitch for corrosion or damage. Repair or replace
components as necessary.
• Check for wear on the hitch ball. If the ball is worn, it is UNSAFE
and must be replaced.
• Check the coupler mechanism for smooth operation. If the latch
handle does not spring open after being disengaged, lubricate
the points on the coupler latch mechanism.
• Check the actuator for excessive wear. If the outer member is
rubbing against the inner, wear marks will show on top of the
coupler just forward of the outer member. Contact an authorized
MasterCraft dealer for replacement parts.
• Check the actuator travel. Excessive actuator travel
(over one inch) when the brakes are applied indicates air in the
brake lines.
• Check the brake fluid in the master cylinder reservoir. On the
actuator, remove the cap to the master cylinder reservoir by
unscrewing the cap in a counter-clockwise direction. The brake
fluid level should be 1/8” below the threads.
