Magnets
Your electric brakes are equipped with high quality electromagnets that are designed to provide the proper input
force and friction characteristics. Your magnets should be inspected and replaced if worn unevenly or abnormally.
Even if wear is normal as indicated by your straightedge, the magnets should be replaced if any part of the magnet
coil has become visible through the friction material facing of the magnet. It is also recommended that the drum
armature surface be refaced when replacing magnets.
Magnets should also be replaced in pairs - both sides of the axle. Always use genuine MDC OEM parts.
Shoes and Linings
A simple visual inspection of your brake linings will tell if they are useable.
Replacement is necessary if the lining is worn (to within 1.5mm or less), contaminated with grease or oil or
abnormally scored or gouged. It is important to replace both shoes on each brake and both brakes of the same axle.
This is necessary to retain the “balance” of your brakes. Be sure to replace your shoes only with genuine MDC parts
available from our outlets.
Corrosion Prevention
It’s important to take steps to prevent corrosion of parts on your trailer to extend the service life. Many ttings
are high tensile and therefor zinc plated. Fittings such as this can benet from additional protection. Some helpful
products to prevent corrosion are “Lanotec”, “WD40”, “Inox” and similar products. These can be spray applied and
do a very good job of protecting metal surfaces, particularly in corrosive and aggressive environments near the
ocean and inland waterways.
Often, we take our campers to salt water environments. Driving through salt water is never recommended as
the residual chloride ions accelerate corrosion greatly. If you are camping near or driving through these kinds of
environments, we highly recommend that your trailer be thoroughly cleaned after use. Flushing the chassis and
washing and rinsing your trailer is important.
