MasterCraft owners must use only DOT 3—preferred—or DOT 4 brake fluid.
DO NOT USE DOT 5 BRAKE FLUID. DOT 5 FLUID WILL DAMAGE THE SEALS IN THE ACTUATOR AND CALIPERS, CAUSING FAILURE OF BRAKES THAT COULD LEAD TO INJURY OR DEATH.
Any other type may not provide sufficient chemistry to protect against overheating. Brake fluid should be completely replaced during annual maintenance (at least once every 12 months or more often if the system has shown evidence of brake fluid loss).
Brake fluid types should never be mixed. Failure to provide required maintenance can cause brake failure, leading to incidents that result in serious injury or even death.
