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 fittings are high
tensile and therefor zinc plated. Fittings such as this can benefit 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 and caravans 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.
Wheels and Tyres
Highway
Your caravan is fitted with 16” wheels and 265/75 R16 Goodride Tyres. The tyres are a “Light Truck” typre with a mud
terrain tread and a maximum load rating on single axle of 1550kg at 80psi.
Recommended highway pressure at tare weight of the caravan is 50-56psi
Recommended highway pressure at ATM of 3000kg is 74-77psi
Off Road
Off road driving requires lower tyre pressures and lower speeds. When driving on rough and corrugated road, a
reduction of speed and controlled deflation of tyres is required to protect the caravan and its suspension from damage.
In extreme circumstances tyre pressures may be reduced significantly. When lowering from highway pressure, a rule
of thumb is to reduce your speed by the same percentage as the lowering of tyre pressure.
Because off road conditions can vary greatly, you must lower your pressures and reduce speed until vibration and
shock through the suspension is at a moderate level to suit the conditions you are experiencing, and the loaded weight
of your caravan.
WARNING: When returning to the highway or when increasing speed, you must reinflate the tyres to correct highway
pressures. Failure to reinflate can cause severe handling problems resulting in injury or death.
