 B. Aircraft Maintenance Configuration
 (1) Energize the aircraft electrical circuits (Ref. TASK 24-41-00-861-002).
 (2) On the panel 400VU, make sure that the Landing Gear control lever is at DOWN.
 (3) On the panel 402VU, make sure that the A/SKID & N/W STRG switch is at ON.
 (4) On the panel 110VU, make sure that the PARK BRK control switch is at OFF.
 (5) Do the EIS start procedure (Upper ECAM DU and lower ECAM DU only) (Ref. TASK 31-60-00-860-001).
 (6) Make sure that the level of fluid in the reservoir of the low-pressure braking control-system is correct.
 (7) Pressurize the Yellow hydraulic system (Ref. TASK 29-10-00-863-002).
 (8) Make sure that the Green hydraulic system is depressurized (Ref. TASK 29-10-00-864-001).

 A. Operational Test of the Alternate Braking with or without Anti Skid
 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------

1. Push in the two brake pedals on the CAPT or F/O side.  On the panel 400VU, the brake yellowpressure triple indicator shows the left and right side pressure values. The pistons related to the Yellow hydraulic system are extended.
 2. Release the brake pedals.  The triple indicator shows that the pressure supplied to the brakes decreases to zero.

 -------------------------------------------------------------------------------ACTION RESULT -------------------------------------------------------------------------------
3.
 Slowly push the brake pedals on the CAPT or F/O side.

4.
 On the panel 402VU, set the A/SKID & N/W STRG switch to OFF.

5.
 Do the same steps as in paragraphs 1 to 3.

 6.
 On the panel 402VU, set the A/SKID & N/W STRG switch to ON.

The pistons related to the Yellow hydraulic system are retracted.
On the panel 400VU:
-
the pressure supplied to the brakes increases in proportion to the pressure you put on the pedals,

 -
the pressure shown at full pedal movement is between 2400 psi (165 bar) and 2700 psi (185 bar).

On the WHEEL page, the STEERING andA/SKID indication comes into view in amber. You can hear the single chime. On the upper ECAM display unit the BRAKES A/SKID N/WS OFF indication comes into view.
You must get the same results.
On the upper ECAM display unit, theBRAKES A/SKID N/WS OFF indication goes out of view. On the WHEEL page the STEERING and A/SKID indication go out of view.
