2011 MasterCraft Trailer Manual

akes not flushed out, severe corrosion can occur.Try the brakes before each trip. On a regularbasis, have the brake linings inspected, necessaryadjustments made and any damaged or worn partsreplaced by an authorized MasterCraft dealer.Wet brakes usually do not hold especially well. Ifthe wheels have been in water, several brake applicationsat slow speeds should dry them out. Ifthe wheel assemblies have been submerged in saltwater, it is important to flush the rotors and calipersthoroughly with fresh water to minimize subsequentcorrosion.• If the stopping capacity does not meet expectations,have the tow vehicle and the trailer brakeschecked for proper operation. The trailer brakesshould be inspected by an authorized MasterCraftdealer.• Review the tow vehicle manufacturer’s recommendationsand instructions for towing.• If the brakes are hot, before launching it is a good idea to allow the brakes to coolfirst. The sudden change in temperature when submerging very hot calipers and rotorsstresses all the parts and could cause damage.• If you are unable to back-up, check the electronically operated back-up valve on theactuator, which is connected to the tow vehicle back-up lights. When energized, thevalve opens and prevents pressure build-up in the system. When it is energized byshifting the tow vehicle into reverse, you should hear a noticeable “click” sound. If youdon’t, check that the electrical connection between tow vehicle and trailer is secure.• When parking the trailer, be sure the actuator is fully extended. This position relievespressure on the brakes. Actuators sometimes freeze up in the compressed position fromcorrosion. This causes the brakes to drag and overheat during subsequent outings.Brake Lockout BracketWhen backing up, the coupler will move backand apply the trailer brakes. The brakes will applyat different levels depending on how fast you backup, the type of brakes the road or surface, andthe angle the trailer is at. Some trailers with discbrakes need an electrical solenoid control to allowthe trailer to back up. This control is wired to theback-up lights on the tow vehicle and when thetow vehicle is put into reverse, this control doesnot allow the trailer brakes to apply.A simple lockout has been included with thisOwner’s Manual (it is not installed on the trailer as it is used only when needed and shouldotherwise not be left on the trailer). When inserted, this bracket will keep the coupler frommoving back and applying the brakes. It should be used when backing over soft ground orup a hill. Use it as follows:1. Place the brake lockout into the slot behind the roller pin on the side of the actuator.2. Slide the brake lockout completely forward in the slot. A washer will keep the brakelockout from falling out while backing up.MasterCraft Trailer Manual • Page 16
