Brake Component Inspection
Walk around the vehicle and inspect brake system components for visible damage.
1. Inspect all visible brake system components for missing fasteners or signs of looseness, such as rust tracks.
2. Inspect the exterior surfaces of brake chambers for damage. Make sure that breather holes are open and free of debris.
NOTE: Do not route air brake lines on top of anything likely to be stepped on.
3. Inspect air brake lines for dents, swelling, kinks, twisting, abrasion, and damage, especially near moving parts.
4. Inspect flex air lines for deterioration or signs of abrasion.
5. Inspect for cracked, worn, or oil-contaminated brake linings and brake drums (or rotors).
6. Check the thickness of the brake linings. Re- place brake linings on all brake assemblies on the axle if any brake linings are worn to less than approximately 1/4 inch (6.4 mm) at the thinnest point.
Saddle Tank Area Inspection
1. Drain the brake system air reservoirs (reservoirs with automatic drain valves only).
2. Inspect the batteries.
2.1 Remove the battery box cover and inspect all visible battery cables for loose wiring or damage.
2.2 Check that the battery hold-down is se- cure.
Engine Compartment Inspection
1. Check the hydraulic clutch reservoir, if equipped. If necessary, add DOT 4 brake fluid.
2. Inspect the radiator and heater hoses, including the clamps and support brackets.
2.1 Inspect the radiator and charge air cooler for damage and accumulated debris. Straighten bent or damaged fins to permit airflow across all areas of the cores.
2.2 Make sure the radiator inlet and outlet hoses are pliable and are not cracking or ballooning.
2.3 Make sure the heater hoses are pliable and are not cracking or ballooning.
2.4 Tighten hose clamps as necessary.
2.5 Ensure hose support brackets are se- curely fastened. Make sure hoses are not located near sources of wear, abrasion, or high heat.
