®

EVERSURE

SPRING BRAKE CHAMBER

(APPLY PARK BRAKE)

10.0.1. Verify that the spring brake has been properly

installed on the spring brake bracket and properly attached

to the slack adjuster.

10.0.2. Apply air pressure (100-120 psi; 6.6-8.0 bar) to

restrain by air force the power spring.

10.0.3. Turn the release bolt nut counter clockwise with a

hand wrench. (DO NOT USE HIGH SPEED OR POWER

DRIVEN IMPACT WRENCH)

10.0.4. Connect a regulated air line to the emergency/

parking brake port (marked “12”) of the chamber (if not

connected previously).

10.0.5. Continue to turn the release bolt nut until the caging

tool is loose. Remove caging bolt nut and washer.

10.0.6. Push the release bolt tool in, turn the release bolt

a quarter-turn counter clockwise and remove it from the

pressure plate key hole.

10.0.7. With hands clear of moving parts, slowly release

the air pressure to the emergency/parking brake port (“12”).

Be sure to exercise caution to prevent pinching of fingers.

10.0.8. Place caging bolt in spring brake tool holder with

T-head down and seated in slot. Install washer and nut up

on exposed threads (this allows the washer to protect the

holder cavity and caging bolt from corrosive elements),

and torque the caging bolt nut to 10-15 lb-ft (14-20 Nm).

10.0.9. Mount the dust plug /weather seal in the keyhole

located at the rear center of the spring brake chamber.

Check around the edge of the dust plug/weather seal to

be sure it is firmly seated.

IMPORTANT: Always re-install the tethered dust plug/

weather seal in the spring brake caging tool key hole.

Failure to do so will result in corrosion and foreign material

ingestion through the key hole which may void the warranty.

Do not use excessive force when installing the dust plug/

weather seal. Extreme force may cause damage and make

it unusable.

Replacement dust plugs can be purchased from your local

Bendix distributor.

WARNING!

Check for proper service and emergency operation

after servicing any part of the brake chamber(s). Check

the brake adjustment if the combination spring brake

was removed/installed. (Follow the vehicle manufac-

turer’s instructions to adjust the brakes).
