Bendix Commercial Vehicle Systems E-14 DUAL BRAKE VALVE 3/04 - Manual (Page 5)

5
After a full application is released, the reading on the test
gauges should fall off to zero promptly. NOTE: the number
one circuit delivery pressure will be about four psi greater
than the number two circuit delivery pressure with both supply
reservoirs at the same pressure. This is normal for the E-14
™
brake valve.
LEAKAGE TEST
Make and hold a high pressure application (80 psi). Coat
the exhaust port and body of the brake valve with a soap
solution. Leakage permitted is a 1" bubble in 3 seconds in
both the applied and released positions. No leakage is
permitted anywhere else.
WARNING! PLEASE READ AND FOLLOW
THESE INSTRUCTIONS TO
AVOID
PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following
general precautions should be observed at all times.
1. Park the vehicle on a level surface, apply the
parking brakes, and always block the wheels.
Always wear safety glasses.
2. Stop the engine and remove ignition key when
working under or around the vehicle. When
working in the engine compartment, the engine
should be shut off and the ignition key should be
removed. Where circumstances require that the
engine be in operation, EXTREME CAUTION should
be used to prevent personal injury resulting from
contact with moving, rotating, leaking, heated or
electrically charged components.
3. Do not attempt to install, remove, disassemble or
assemble a component until you have read and
thoroughly understand the recommended
procedures. Use only the proper tools and observe
all precautions pertaining to use of those tools.
4. If the work is being performed on the vehicle’s air
brake system, or any auxiliary pressurized air
systems, make certain to drain the air pressure from
all reservoirs before beginning ANY work on the
vehicle. If the vehicle is equipped with an AD-IS
™
air dryer system or a dryer reservoir module, be
sure to drain the purge reservoir.
5. Following the vehicle manufacturer’s
recommended procedures, deactivate the electrical
system in a manner that safely removes all
electrical power from the vehicle.
6. Never exceed manufacturer’s recommended
pressures.
7. Never connect or disconnect a hose or line
containing pressure; it may whip. Never remove a
component or plug unless you are certain all
system pressure has been depleted.
8. Use only genuine Bendix ® replacement parts,
components and kits. Replacement hardware,
tubing, hose, fittings, etc. must be of equivalent
size, type and strength as original equipment and
be designed specifically for such applications and
systems.
9. Components with stripped threads or damaged
parts should be replaced rather than repaired. Do
not attempt repairs requiring machining or welding
unless specifically stated and approved by the
vehicle and component manufacturer.
10. Prior to returning the vehicle to service, make
certain all components and systems are restored
to their proper operating condition.
VALVE REMOVAL
1. Identify and mark or label all air lines and their respective
connections on the brake valve to facilitate ease of
installation. Disconnect all air lines.
2. Remove the valve from its mounting on the vehicle. For
manifold-type valves, remove the brake valve and manifold,
in tact, from the vehicle.
DISASSEMBLY (SEE FIGURE 9)
The following disassembly and assembly procedure is
presented for reference purposes only. Always have the
