Check of the Brake Accumulator Precharge Pressure.
SUBTASK 12-15-11-480-001
WARNING: MAKE SURE THE DOWNLOCK PINS ARE INSTALLED ON ALL THE LANDING GEAR.
WITHOUT THE DOWNLOCK PINS, THE LANDING GEAR COULD RETRACT AND CAUSE
INJURIES TO PERSONS AND DAMAGE TO EQUIPMENT.
(1) If the downlock pins are not installed in the nose and main landing gear, do this task: Landing
Gear Downlock Pins Installation, TASK 32-00-01-480-801.
SUBTASK 12-15-11-480-002
(2) Make sure the tires have chocks installed around them (CHOCK INSTALLATION,
PAGEBLOCK 10-11-05/201).
SUBTASK 12-15-11-860-001
(3) Release the parking brake.
SUBTASK 12-15-11-860-002
(4) For hydraulic systems A and B, do this task: Hydraulic System A or B Power Removal,
TASK 29-11-00-860-805.
SUBTASK 12-15-11-870-001
(5) Operate the brake pedals until the brake accumulator pressure gauge [104] shows no change in
the pressure.
NOTE: You will have to operate the brake pedals approximately 12 times to fully release the oil
pressure from the accumulator.

(6) Wait ten minutes to allow accumulator gas to reach equilibrium.
SUBTASK 12-15-11-610-001
(7) Do the steps that follow to do a check of the accumulator precharge pressure:
(a) Use the charging instructions placard [105] to find the correct accumulator pressure for the
current ambient temperature of the airplane.
NOTE: The charging instructions placard [105] is located next to the brake accumulator
pressure gauge [104].
(b) Make sure the pressure that shows on the brake accumulator pressure gauge [104] is
within +/- 50 psi (+/- 300 kPa) of the pressure you obtained from the graph on the
charging instructions placard [105].
(c) If the pressure shown on the brake accumulator pressure gauge [104] is not in the correct
pressure range of the charging instructions placard [105], do this task: Hydraulic Brake
Accumulator Servicing, TASK 12-15-11-420-801.
