Drum Brakes:
• Place wheel chocks firmly against the wheel before performing this procedure.
• Remove the plug from the center of rear brake chamber on the drive axle.
• Remove the caging tool from its holder on the brake chamber and insert the tool into hole.
Turn clockwise to engage.
• Screw nut and washer onto caging tool. Use a wrench to tighten the nut, compressing the
internal spring to release the brake.
• Repeat procedure for the other side.
• After towing, or when air pressure is again available, loosen the nut and remove the tool.
Return the caging tool to its original location and replace the plug.
• Repeat for the other side.
WARNING:
Failure to securely chock the wheels can result in the motorhome rolling when the
spring brakes are released. Severe injury or death can occur.
TIRES
Tires designed for the motorhome are a very technical and engineered product. Since the tire is the
only contact the motorhome has with road surface, it is critical that proper tire pressures be main-
tained. Improper tire pressure will lead to abnormal wear or sudden tire failure. The motorhome
must be weighed fully loaded before proper tire inflation pressures can be determined. The following
information concerning tires and weighing the motorhome are set in the order in which the process is
performed or experienced.
The tire performs additional functions of traction for moving stopping and steering, as well as
providing a cushion for the motorhome. Modern tire technology blends a unique mix of chemistry,
physics and engineering to provide a high degree of comfort, performance, efficiency, reliability and
safety. To obtain the maximum wear and best service from tires, it is helpful to understand the
components and functions of the tire.
