Possible cause: Remedy:Leaky or seized brake wheel Replace/rebuild the wheel cylinder and replacecylinder.the brake shoes if contaminated with brake fluid.Clean the drums and other hardware, readjustthe brakes and bleed the brake system.Possible cause:Damaged or frozen brakemechanism.Remedy:Rebuild or replace the brake unit.Problem: More than one brake is overheating.Isolate the problem to the actuator or the brakes by:1. Fully extend the actuator.2. Remove the master cylinder reservoir plug.3. Check that the reservoir is properly filled.4. Manually push the actuator inner member in or use a screwdriver to stroke the pushrod.5. In the first 1/8” of stroke, the reservoir fluid will either remain dead calm or swirlaround. If the fluid swirls fluid is allowed to return to the reservoir when the actuatoris extended. This means the actuator is functioning properly and it is necessary totroubleshoot the brakes.Possible cause:Trailer has been stored with the actuator compressed and rust has caused the brakesto freeze up.Remedy:Remove the brakes. Clean, repair or replace the components as necessary. This isbest done by an authorized MasterCraft dealer.Possible cause:Pinched or kinked brake lines.Remedy:Check the brake lines and replace as necessary.If fluid does NOT move in Step 5, it means the brake system is remaining pressurizedand there is an actuator issue. Troubleshoot the actuator.Possible cause:Pulled breakaway cable and the push rod has not been reset.Remedy:Reset the breakaway cable and install the clip.Other potential issues with the actuator include:• the fluid return hole in the master cylinder is clogged or is not correctly positioned;• corrosion in the master cylinder is freezing the piston or not allowing it to fully retract,which is usually caused by a trailer being stored with the actuator compressed;• or some other malfunction or damage that is keeping the master cylinder from retracting.These are more complex issues and should be addressed by an authorized MasterCraftdealer.MasterCraft Trailer Manual • Page 34
