===Introduction===

Your motorhome is equipped with dual service air brake systems for front, rear and tag axle brakes , with integral fail/safe operation; and manual/automatic rear spring (parking) brakes. As shown in the air brakes system diagram in Section X, the service brakes are completely independent systems, each including a reservoir and separate distribution lines and valves. A separate reservoir is also supplied for the rear spring brakes , which function independently of the service brakes. All three reservoirs are pressurized from a single compressor. Both service brake systems are brought into operation each time the brake treadle is depressed to slow or stop the coach. Reservoir pressure for each service brake system is monitored by a respective pressure gauge on the front panel ; system failure(s) are indicated by low pressure readings , illumination of the Low Air failure lamp and sounding of buzzer (item 10, figure 2-3).

'''Note:''' With the front brake system service reservoir fully charged, enough air pressure is available to provide for four full releases of the rear spring brakes. This will allow the coach to be brought to a safe position until repairs can be accomplished.

Besides providing the compressed air supply for the coach braking systems , the compressor also provides the air supply for the entry step, side-slide mechanism on driver's and co-pilot's seats, front air vents , stepwell cover plate, tag axle and air suspension system (air bags) - all via separately controlled solenoid switches operated from the dash , or at other locations throughout the coach. (This compressed air source is furnished from the front right side reservoir.) A compressed air outlet fitting and air gun is contained in the center storage compartment on the left side of the coach , convenient for blowing out the water system, inflating tires, and so on. A Schrader valve (air connection} is available in the engine compartment to allow the air system to be pressurized from a "shop" source without the necessity of starting the engine.

=== Compressed Air System Air Dryer ===

===Compressed Air System Air Dryer===

The air dryer unit collects and removes moisture and contaminants from the compressor air output before the air reaches the reservoirs . This unit is different from a reservoir drain or an after-cooler in that it provides dry air for the brake system by eliminating the possible accumulation of condensate in the system reservoirs. Note that each reservoir also has a drain cock on the bottom for draining accumulated moisture. This assure s a long maintenance-free life for air brake system components due to the removal of system contaminants. The air dryer is located between the compressor discharge (output) line and the compressed air reservoirs . A safety valve mounted in the air dryer housing assembly protects against excessive pressure buildup. The desiccant cartridge and pleated paper oil filters are easily removable and replaceable as a complete serviceable unit. The desiccant "beads" which provide the drying action have a large capacity for absorption due to their combined surface area. In addition, an internal thermostatically-controlled heating element prevents freeze-ups on the purge drain valve when the unit is used during sub-freezing temperatures. Purging of the dryer is automatic , exhausting combined oil and water residue to the atmosphere. At the same time that the contaminants are purged the reverse air flow across the desiccant material removes the accumulated moisture and reactivates the desiccant. Cartridge replacement should be accomplished at 3 years or 300,000 miles; sooner , if the cartridge has become contaminated .

'''Caution''' Cooling fan is driven by hydraulic pressure. Flow is controlled electrically by a thermostat which senses engine coolant temperature. Any time the engine is running the fan may engage and start without warning. Also on hydraulically driven fans, the fan may start and run for several seconds when the engine is shut off or if electrical power is interrupted. Shut off engine and wait for fan to stop before servicing. When inspecting or servicing engine or other components in engine compartment the engine control switch must be placed in OFF or REAR position to prevent starting of the engine from the driver's area.
