Service Procedure

NOTICE:
A CORRECTLY MOUNTED BRAKE HOSE MAY SHOW EVIDENCE OF INTERMITTENT LIGHT CONTACT WITH THE PARK BRAKE CABLE BRACKET. THIS IS NOT THE AREA OF CONCERN.

ONLY HOSES THAT ARE MISPOSITIONED AND SHOW EVIDENCE OF CONTACT OR POTENTIAL FOR CONTACT WITH THE TOP INBOARD SIDE OF THE AUXILIARY SPRING MOUNTING BRACKET SHOULD BE REPLACED.

INSPECTION (ON HOIST)

1. Raise vehicle on frame hoist and suitably support.








2. Inspect both (right and left) rear brake hoses for proper position (See Figure 1 and 2).

3. If hose is properly positioned (shown in Figure 2), proceed to Step 16. If hose is incorrectly positioned (shown in Figure 1), proceed to Step 4.

INSPECTION (ON GROUND OR DRIVE-ON HOIST)

1. Position vehicle on drive-on hoist or leave on ground.

THIS METHOD OF INSPECTION MAY MAKE IT EASIER TO OBSERVE MISPOSITIONED HOSES.





2. Load rear suspension to simulate vehicle suspension traveling through jounce. (Auxiliary spring mounting bracket to brake hose contact will ONLY occur during this travel). Inspect both right and left rear brake hoses for contact (See Figure 3).

3. If hose is properly positioned (hose is located rearward of the auxiliary spring mount bracket) proceed to Step 16. If brake hose is incorrectly positioned (contact or potential for contact exists) proceed to Step 4.
