Bleeding
WARNING
1. Turn vehicle power switch to ON position to charge the brake system (TM 9--2350--292--10).
WARNING
Depressing brake pedal farther than necessary causes pressure in
brake cylinder to rise significantly. Brake pressure can rise to 900
psi (6201 kPa) if brake pedal is depressed too far. Use only as
much pedal travel as required to achieve steady fluid flow.
2. Depress brake pedal sufficiently to permit pressure to flow through brake cylinder (1).
3. Slowly loosen cylinder bleed screw (2) and allow fluid to flow until a steady stream of fluid is observed. This indi-
cates that all trapped air has been purged from cylinder (1).
4. Tighten cylinder bleed screw (2). Release brake pedal.
5. Turn vehicle MASTER switch to OFF (TM 9--2350--292--10). Exercise brake pedal while monitoring pressure
gauge (3) until the system pressure drops below 150 psi (1034 kPa).
6. Slowly loosen swivel fitting (4) at pressure switch (5) and allow fluid to flow until a steady stream of fluid is ob-
served. This indicates that all trapped air has been purged from lines.
7. Tighten swivel fitting (4).
8. Check hydraulic reservoir fluid level (TM 9--2350--292--10).
