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
performing 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 valuable guide in determining the best maintenance
interval for air brake system components. At a minimum,

6 months or 1500 operating hours, whichever comes fi rst,
for proper operation. Should the E-6
meet the elements of the operational 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 three (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
deterioration 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!
