FIGURE 8 - RELEASED MODE

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

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

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

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

appropriate maintenance kit on hand, and use its instructions

in lieu of those presented here. Refer to Figure nine

throughout the procedure.
