Inspection

1. Turn the air suspension switch OFF, if equipped, then raise the vehicle on a hoist.





2. Inspect the brake tubes along the left frame rail directly below the driver's door area and above the transmission crossmember. See Figure 1.

NOTE:
Technicians must judge for themselves, on a case by case basis, if an acceptable splice can be made based on the condition of the brake tubes.

^ If the brake tubes are not leaking - proceed to Brake Tube Adjustment in this Attachment III.

^ If either one (1) or both brake tubes are leaking and the tubes can be spliced - proceed to Brake Line Repair in this Attachment III.

^ If either one (1) or both brake tubes are leaking and cannot be spliced - lower the vehicle down but not off the hoist, and proceed to Brake Tube Replacement in this Attachment III.
