BRAKING SYSTEM - Air Breather
DESCRIPTION AND OPERATION
There are two non-pressurised air breathers used in
the air system, one on each of the brake pressure
converters. Air displaced on the atmospheric side of
the air piston in the pressure converter exhausts
through the air breather. Refer to Section 250-0000,
AIR BRAKING SYSTEM SCHEMATIC, for
relationship of breathers to pressure converters.
MAINTENANCE
The air breather is manufactured in glass-filled nylon
and glass-coupled polypropylene, ensuring the
product does not corrode even in the most arduous
applications.
Note: An air system maintained to proper
specification can lead to prolonged component life.
Refer to Section 250-0200, AIR DRIER, for correct
air filtration service procedures.
