Magnets
Your electric brakes are equipped with high quality electromagnets that are designed to provide the proper input force
and fricon characteriscs. 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 fricon 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 inspecon 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 Prevenon
It’s important to take steps to prevent corrosion of parts on your trailer to extend the service life. Many fings are high
tensile and therefor zinc plated. Fings such as this can benefit from addional protecon. 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 protecng metal surfaces, parcularly in corrosive and aggressive environments near the ocean and inland waterways.
Oen, we take our campers and caravans to saltwater environments. Driving through saltwater 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 aer use. Flushing the chassis and washing
and rinsing your trailer is important.
