valve not meet the elements of the operational tests
noted in this document, further investigation and service
of the valve may be required.
Every 3 months, 25,000 miles, or 900 operating
hours:
Misalignment between the pedal components and valve will
cause valve leakage during a brake application. Inspect
the pedal to see that all cotter pins, rollers, and pivot pins
are in place. Damaged or missing components should be
replaced before operation of the vehicle. Parts showing
signs of excessive wear should also be replaced.
Free pedal travel should be checked as follows: Check
to be certain the plunger is in contact with spring seat.
The stop button should be adjusted so that the roller and
plunger just contact.
To identify if the pedal components are excessively worn,
grab the pedal at the foot pad and push side to side. If
the pedal has movement over .250 inches then the pedal,
mounting plate, and fulcrum pin, should be replaced.
Other signs of wear that will require inspection are
deterioration of the boot, plunger wear, and wear in the
mounting plate at the fulcrum pin holes. If the wear is
excessive, the fulcrum pin holes become oval in shape.
The plunger bore and fulcrum pin holes should always
be liberally coated with barium grease per BW-204-M
(Bendix part number 246671). These parts may require
more frequent lubrication if the vehicle’s interior is regularly
pressure washed as part of a maintenance program.
Clean the exhaust cover as needed depending on type
of service.
On high-offset pedal applications, the cotter pin that
retains the fulcrum pin may become damaged. This can
be identifi ed by wear marks on the side of the mounting
plate. To maximize the life of the cotter pin, the fulcrum
pin should be installed such that the cotter pin is located
on the same side of the mounting plate as the brake pedal
pad. If the cotter pin is found to be opposite of the pedal
pad, the fulcrum pin should be reversed and secured with
a new cotter pin.
SERVICE CHECKS
OPERATING
Check the delivery pressure of both primary and secondary
circuits using test gauges known to be accurate. Depress
the pedal to several positions between the fully released
and fully applied positions, and check the delivered pressure
on the test gauges to see that it varies proportionately with
the movement of the brake pedal.
