Brake Systems - Air Brakes - Monaco 2002 Diplomat Service Manual

• Make sure to check shock absorbers for leaking hydraulic oil
and worn or broken end connectors. If a broken shock is found,
replace it immediately. The shock absorber will normally limit
the rebound of an air spring and keep it from overextending.
• Check the tightness of all mounting hardware (nuts and bolts). If
loose, tighten. Do not over-tighten.
Cleaning:
The approved cleaning method is to use soap and water, methyl alcohol,
ethyl alcohol and isopropyl alcohol. Unapproved cleaning methods include
all organic solvents, open flames, abrasives and direct pressurized steam
cleaning.
The motorhome is equipped with air brakes using much the same system
as over the road trucks. This type of braking system is efficient. Proper
maintenance and lubrication is the key to keeping the brake system in proper
working order. The brake system on the motorhome is designed to accommodate
the weight of the vehicle and towing loads. This system differs from a
conventional automotive hydraulic braking system and should be treated
differently.
When operating a vehicle equipped with air brakes consideration needs to
be given to stopping distances and air system pressures. The heavier the
vehicle, the greater the kinetic energy. The motorhome requires longer
stopping distances. Each brake application uses air from the air system. Give
attention to the air gauge as well as the surroundings. Engine speed is directly
proportional to how fast the air system is replenished. Prepare for downhill
grades. Grades are generally posted in percentages. It may be necessary to
select a lower gear. Make use of the engine or exhaust brake. When making
brake applications use individual short applications down long hills rather
than "riding" the brakes. This will extend the life of the brake linings. Avoid
overheating the brakes. Hot brakes have less stopping power. When
maneuvering the motorhome around in small areas, or backing into spaces,
several individual brake applications might be made. Watch the air gauge.
Plan ahead when parking to make it easier on yourself. When preparing to
back into a space swing the motorhome so it is aligned with the parking slot
before backing up.
The air braking system on the motorhome is equipped with several safety
features unlike that of automotive hydraulic braking systems. One safety feature
is a low air pressure warning system. Should a low air condition arise while
the vehicle is under operation a warning buzzer will sound and a dash warning
light will illuminate alerting the operator of the situation. This warning
occurs at approximately 60-65 psi (pounds per square inch).
