D. Preparation for the Replenishment
(Ref. Fig. 302/TASK 32-43-00-991-005)
(1)
On the reservoir 2624GM:
-disconnect the drain hose (aircraft system) from the bleed valve
-connect a transparent hose on the bleed valve to collect the hydraulic and monitor the presence of air bubbles during the filling operation.
-put the other end of the hose into a container
-cut, remove and discard the lockwire, then open the bleed valve.
(2)
On the alternate-brake distribution dual-valve 2577GM, remove the plugs of the bleed valves. Remove and discard the lockwire and open the bleed valve on the unions J and K.
(3)
Install a filling valve on each of the bleed valves.
(4)
Connect the FILLING TOOL - BRAKING SYSTEM (98D29003502000) between the Green reservoir drain valve and the filling valves installed on the bleed valves of the alternate brake distribution dual valve 2577GM.
NOTE : Fill all the line of the filling unit. Make sure that there
____
are no air bubbles in the connection

(5) On each brake unit, connect a hydraulic pressure gauge valve at the Yellow system bleed valve. Then open the bleed valves.
4. Procedure
_________
Subtask 32-43-00-611-052
A. Bleeding and replenishment of the Alternate Brake Control Reservoir
(1)
Depressurize the brake yellow-pressure accumulator 2582GM (Ref. TASK 29-10-00-864-002).
(2)
Pressurize the green hydraulic reservoir (Ref. TASK 29-14-00-614-002)
NOTE : During the replenishment procedure monitor:
____
-
the fluid level of the green hydraulic reservoir. If necessary add fluid to the green hydraulic reservoir (Ref. TASK 12-12-29-611-001) or (Ref. TASK 12-12-29-611-002).
