(Note that failure to follow these routine procedures may result in failures that are not
covered under warranty.)
Failure to follow maintenance procedures
as outlined in this Owner’s Manual may
result in component failure. Failure may
also result in loss of control or other mal-
function that could potentially lead to serious injury or death! Such failure is
not covered under warranty.
• Hoseoffthebrakerotorsandcalipers,alongwithallotherpartsofthetrailerthathave
come in contact with salt water or brackish water, as this will minimize corrosion. A
fresh water flush of the system is the most critical aspect of trailer maintenance.
• Extremelythick,heavyrustonrotorsurfaceswillnotallowthewheelassemblytorotate
freely, resulting in heat build-up and premature wear on components. Clean or replace
components as necessary.
• Brakepadsmustbereplacedwhen3/32”(.094”)orlessofthepadfrictionmaterial
is left.
Brake pad replacement should be per-
formed by an authorized MasterCra
dealer. Improper pad replacement may
decrease braking eectiveness, potentially
resulting in a collision as a result of failure to stop the tow vehicle within an
acceptable distance.
• Rotorsshouldberesurfacedbyaqualifiedbrakespecialistifextremegallingorwear
marks are present.
Worn rotors must be replaced. Failure to
do so may result in brake failure, which
may cause serious injury or death.
• Becertainthathydraulicfluidiscleanandthefluidleveliswithin½”ofthetopofthe
reservoir. (See the Actuator and Axle information contained in this Owner’s Manual.) Do
not fill beyond that level. Brake systems use DOT 3 (preferred) or DOT 4 hydraulic fluid.
• Checkforleaksinthebrakelinesandfittings.Leakswillleadtolossoftrailerbraking
ability. Present the trailer to an authorized MasterCraft dealer for repair if lines or fittings
appear to be leaking.
• Aluminumwheelsalsorequireattentiontoroutinemaintenance,particularlyinkeeping
them clean. Failure to do so may result in damage that is not covered by warranty.
• Thetrailerandwheelsshouldbewashedweeklyduringboatingseason,andafter
every use if the trailer has been submerged in salt or brackish water. Use a soft brush,
mild detergent and/or mild degreaser. A quality spray-on wheel cleaner may also be
used. Ensure that any product used is specifically indicated for use on aluminum. (Many
cleaners are too harsh and will result in pitting or other damage to the wheel surface.)
Many car washes use strong chemicals and should be avoided when that is the case.
Removing road film, contaminants and brake dust (all of which retain moisture) is critical
to ensuring that the wheels will retain their luster and quality finish for a long period of
