• Block wheels securely before attempting this procedure.
• Remove the plug from the center of rear brake can.
• Remove the caging tool from its holder on the rear brake
can and insert it into the hole. Turn the tool clockwise to
engage.
• Use a wrench to tighten the nut down, which compresses
the internal spring, releasing the brake.
• Repeat for the other side.
• After towing, or when air pressure is again available,
loosen the nut and remove the tool. Return the tool to its
original location and replace plug.
• Repeat for the other side.
WARNING: Do not attempt to disassemble brake
canisters without special tools and without having
studied specific manufacturer’s instructions.
Canisters contain springs under very high tension.
Improper handling could result in component dam-
age or personal injury.
The tire designed for the motorhome is a very technical and precisely engi-
neered product. To obtain the maximum wear and best service out of the tires
it is helpful to understand the function of a tire. A tire is a “container” that
holds air. It is the combination of air and tire casing that supports the
motorhome and its contents. In addition, since the tire is the only contact the
motorhome has with the road surface, it must provide other functions such as
traction for moving, stopping, steering and providing a cushion for the
motorhome.
The most important factor in maximizing the life of the tires is maintaining
proper inflation. Driving on any tire that does not have the correct inflation
pressure for the load of the motorhome is dangerous and may cause premature
wear, tire damage and/or loss of control of the motorhome.
A tire that is underinflated will build up excessive heat that may go beyond
the design limits of the rubber and radial cords. This could result in sudden
failure. A tire that is underinflated will also cause poor motorhome handling,
rapid and/or irregular tire wear and an increase in rolling resistance which
results in a decrease of fuel economy.
Over-inflation will reduce the tire’s footprint/contact patch with the road,
thus reducing traction, braking capacity and handling of the motorhome. A tire
that is over-inflated for the load will have a harsh ride, uneven tire wear and
becomes susceptible to impact damage.
