pressure on the delivery side of the primary piston equals
the effort exerted by the driver's foot on the treadle. A
balanced position in the secondary portion is reached when
air pressure on the secondary side of the relay piston closely
approaches the air pressure on the primary side of the relay
piston.
When the brake treadle is fully depressed, both the primary
and secondary inlet valves remain open and full reservoir
pressure is delivered to the actuators.
RELEASING: PRIMARY CIRCUIT
With the brake treadle released, mechanical force is
removed from the spring seat, graduating spring, and
primary piston. Air pressure and spring load moves the
primary piston, opening the primary exhaust valve, allowing
air pressure in the primary delivery line to exhaust out the
exhaust port.
RELEASING: SECONDARY CIRCUIT
With the brake treadle released, air is exhausted from the
primary circuit side of the relay piston. Air pressure and
spring load move the relay piston, opening the secondary
exhaust valve allowing air pressure in the secondary
delivery line to exhaust out the exhaust port.

PREVENTIVE MAINTENANCE
Important: Review the Bendix Warranty Policy before per-
forming any intrusive maintenance procedures. A warranty
may be voided if intrusive maintenance is performed during
the warranty period.
No two vehicles operate under identical conditions, as a
result, maintenance intervals may vary. Experience is a valu-
able guide in determining the best maintenance interval for air
brake system components. At a minimum, the E-6
valves should be inspected every 6 months or 1500 operat-
ing hours, whichever comes first, for proper operation. Should
™
™
the E-6
/E-10
valves not meet the elements of the opera-
tional tests noted in this document, further investigation and
service of the valve may be required.
Visually check for physical damage to the brake valve such
as broken air lines and broken or missing parts.
Every 3 months, 25,000 miles, or 900 operating hours:
Clean any accumulated dirt, gravel, or foreign material away
from the heel of the treadle, plunger boot, and mounting
plate.
Lubricate the treadle roller, roller pin, and hinge pin, with
Barium grease per BW-204-M (Bendix part 246671).
Check the rubber plunger boot for cracks, holes or deterio-
ration and replace if necessary. Also, check mounting plate
and treadle for integrity.
Apply a thin layer of Barium grease, per BW-204-M (Bendix
part 246671), between plunger and mounting plate – do not
over oil!
