A. Safety Precautions
(1) Put the warning notice(s) in position to tell persons not to operate the landing gear control lever and the brake pedals.
Subtask 32-42-00-860-068
B. Aircraft Maintenance Configuration
(1)
Depressurize the Green and Yellow hydraulic systems (Ref. TASK 29-10-00-864-001) (Ref. TASK 29-10-00-864-002).
(2)
Make sure that the PARKING BRK control switch is set to OFF before you do the deactivation.
NOTE : If the brake unit can not move, if the stators, rotors or
____
torque-tubes are damaged:
-remove the brake unit. This causes two deactivations:
*
Deactivation without removal of the brake,
*
Deactivation with removal of the brake.

(1)
Loosen the two knurled sleeves (1) and (4) of the half couplings (2) and (3). Turn and disconnect the half couplings.
(2)
Clean the sleeves (1) and (4) and apply two or three turns of the wide self-adhesive fabric tape 20 mm (0.7874 in.) to 30 mm (1.1811 in.).
(3)
Tightly wind three or four turns of the corrosion-resistant steel lockwire dia 0.8 mm around the tape on the sleeves (1) and (4).
(4)
Twist the lockwire and put it through the nearest locking hole you can get access to in the hexagonal head of the fixed half couplings
(2) and (3).
Tighten the lockwire and twist it.
(5)
Remove the two bleed screw plugs (6) from the bleed screw.
(6)
Connect a vinyl hose to a bleed screw (5) and put the other end in a container that contains HYDRAULIC FLUIDS (Material No. 02-003).
(7)
Slowly loosen the bleed screw (5) to release hydraulic residual pressure from the brake.
(8)
Tighten the bleed screw.
(9)
Disconnect the vinyl hose.
(10) Install the bleed screw plug (6) on the bleed screw (5).
(11) Do the same operations for the other bleed screw.
