2) Gradually supply 100 psi of air pressure to the parking brake port (12) of the actuator.

3) Rotate the release bolt counterclockwise until resistance is encountered.

4) Seat the release bolt in the caged position by applying torque of 25 lb-ft. The release bolt and push rod

should be in the position shown in Figure 1a.

5) With hands clear of moving parts, slowly release the air pressure to the parking brake port (12). Be sure to

exercise caution to prevent pinching of ﬁ ngers.

Notes

As always, follow all recommended safety procedures when performing any service on your vehicle.

1) The release bolt cannot be removed from the parking brake.

2) The nut is permanently attached to the release bolt.

3) Unless a vehicle must be moved in an emergency situation, NEVER ATTEMPT to Cage or Un-Cage the

parking brake without applying air pressure (100 psi) to the parking brake port (12). This practice may

damage the caging bolt and/or the parking brake which could result in the need to replace the spring brake

actuator.

4) DO NOT USE an impact wrench to rotate the caging bolt.

5) Please refer to service data sheet SD-23-7541 (BW7308) for complete service instructions for Air Disc Brakes
