b. Start engine (TM 9-2320-269-10), let air pressure build up, and shut off engine (TM 9-2320-269-
c. If draincocks (2) show signs of leakage, tighten using 9/16-inch wrench, or replace (page 2-585)
d. If reservoirs (1) show signs of leakage, replace (page 2-570 and 2-574) as needed.
Step 3. Inspect brake hoses (4) for damage.
b. If hoses (4) are bent or pinched between vehicle components, remove, reroute, or replace as
