[. . . ] At that time, MasterCraft Trailer Manual · Page 13 it is strongly recommended that the owner not mix radial and bias tires as it may affect the trailer/tow vehicle handling and safety. MasterCraft dealers offer replacement tires; if the owner chooses to go elsewhere, be certain that the replacement tires meet the manufacturer's requirements and integrate with any tires remaining on the trailer. a x l e s a n d l uThe trailer Cequippedi with nTrailer Buddy Axle b r i is at o a utilizing the VAULT bearing protector with specially formulated Hybrid OilTM lubricant. The VAULT combines the benefits of oil and grease, lubricating and protecting the wheel bearings in a sealed pressurized chamber impenetrable by outside elements. The system has a number of unique features not found on conventional trailer axles. The slight (3-6 psi) pressure within the VAULT system generated inside the hub chamber will not damage the inner oil seals. The pressure inside the hub is needed to keep water out of the hub chamber when the hub is submerged underwater during launch and retrieval. Inspection or replenishment of the lubricant is not required as part of the routine maintenance. At ambient temperatures the oil is thick, with a viscosity approaching grease. As the bearing temperature rises during towing, the oil thins out, replenishing the bearings with lubricant and dissipating heat. 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. 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. 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. [. . . ] Worn shock absorber in the actuator. Possible cause: Remedy: Possible cause: Air in the brake lines allowing the actuator to travel too far. Possible cause: Remedy: Check for leaks and re-bleed the brakes. Clunking noise is typical for these types of brakes as long as braking performance is normal. Trailer is equipped with "free backing brakes. " Remedy: Problem: When braking, brakes repeatedly come on and release. Braking is not smooth, a condition called "chucking. " Possible cause: Worn out shock absorber in actuator. Correct as necessary. Possible cause: Possible cause: Remedy: Remedy: Not enough tongue weight or Correct as necessary. [. . . ]
