TM 9--2350--292--20--20355 00--8BRAKE LINKAGE ALIGNMENT, ADJUSTMENT AND BLEEDING(OLD CONFIGURATION) -- CONTINUED0355 00BleedingWARNING1. Turn vehicle power switch to ON position to charge the brake system (TM 9--2350--292--10).WARNINGDepressing brake pedal farther than necessary causes pressure inbrake cylinder to rise significantly. Brake pressure can rise to 900psi (6201 kPa) if brake pedal is depressed too far. Use only asmuch 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 pressuregauge (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).Figure 16745321NOTEFOLLOW--ON MAINTENANCE:Close subfloor access plate #16, if opened (WP 0454 00)Install hull engine compartment access covers, if removed(WP 0434 00)Install subfloor access plate #6, if removed (WP 0454 00)Install powerpack, if removed (WP 0188 00)END OF TASK
