Maintenance
NOTE: Failure to follow these routine procedures may result in fail-
ures that are not covered under warranty.
Failure to follow maintenance procedures as outlined in this   Own-
er’s Manual may result in component failure. Such failure is not 
covered under warranty. Failure may also result in loss of control 
or other malfunction that could potentially lead to serious injury or 
death!
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 wa-
ter, 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 performed by an authorized 
MasterCraft dealer. Improper pad replacement may decrease 
braking effectiveness, 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 ex-
treme 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 
1/8” from the bottom of the threads on the reservoir plug. (See the 
Actuator and Axle information contained in this section of the Own-
er’s Manual.) Do not fill beyond that level. Brake systems use DOT 3 
(preferred) or DOT 4 hydraulic fluid. 
DO NOT USE DOT 5 BRAKE FLUID. DOT 5 FLUID WILL DAMAGE THE 
SEALS IN THE ACTUATOR AND CALIPERS, CAUSING FAILURE OF 
THE BRAKES THAT COULD LEAD TO INJURY OR DEATH.
NOTE: Care must be taken to avoid brake fluid coming in contact 
with the trailer paint. Brake fluid will damage paint! Such damage 
is not covered under warranty!
