[. . . ] NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA) If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, DO NOT USE THE VEHICLE. You should immediately inform the National Highway Traffic Safety Administration (NHTSA) in addition to notifying MasterCraft Boat Company. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer, or MasterCraft Boat Company. [. . . ] For optimal performance, only UFP's Hybrid Oil Lubricant should be used in this system. Adding or changing the lubricant in the VAULT system is neither necessary nor recommended during the first five years of service. After that time, the maintenance requirements should be undertaken only by an authorized MasterCraft dealer and only the lubricant specified above should be used. If the bearings need to be adjusted or replaced, the work should be done only by an authorized MasterCraft dealer. Failure to contact MasterCraft for pre-approval during the warranty period will void the warranty. The wheel bearings have been precisely torque-set at the factory. 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 check 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", the bearings may need to be readjusted. A slight amount of oil seepage at the rear seal is normal and necessary to lubricate the wiper lip of the seal for long life and sealing contaminants out. If excessive leakage is occurring, however, contact an authorized MasterCraft Dealer for assistance. b r a k ioffer severalsadvantages overm brakes. Disc brakes have improved ren g y s t e drum Disc brakes MasterCraft Trailer Manual · Page 14 sistance to fade on downhill grades. They are self-adjusting, so as the pads wear, braking efficiency is not reduced. This type of brake also recovers quickly after being submerged. They also require less maintenance, are easier to flush out, and are less susceptible to water-induced corrosion. The trailer's brakes are designed to energize automatically when the tow vehicle's brakes are applied. These are known as "surge brakes. " (Note: Some jurisdictions do not allow surge brakes. Always check within the locality in which you will be towing. ) When the vehicle slows down or stops, the forward momentum (surge) of the trailer against the hitch ball develops hydraulic pressure in a master cylinder inside the trailer brake actuator. Hydraulic lines are used to transfer pressure to the brakes and engage them. In most states, trailers with a Gross Vehicle Weight Rating (GVWR) of 1, 500 pounds or more are required by law to have brakes on all wheels. (Auto manufacturers generally recommend brakes even with lighter trailers. ) Trailer brakes must be maintained in good working condition at all times. Inspect the brake system on a regular basis and verify proper fluid level in the actuator. The loss of adequate braking could result in serious injury or death and/ or property damage.
