A. Test
(1) Do the operational test of alternate braking with anti-skid (Ref. AMM TASK 32-43-00-710-001).
(2) Make sure that the related pistons of the wheel 4 do not extend.

A. If the test confirms the fault:
- do a check of the connection of the related self-sealing coupling.
(1) If not correct:
- correctly adjust the related self-sealing coupling.
(2) If the fault continues:
- do a check for leaks on the hydraulic line between the safety valve (2621GM) and the brake unit (wheel 4).
(a) If there are leaks:
- repair the leaks and reactivate the safety valve (2621GM).
(b) If there are no leaks and if the fault continues:
- do a check for leaks on the alternate brake pistons of the wheel 4.
1 If there are leaks:
_
- replace the BRAKE-WHEEL 4 (2642GM) (Ref. AMM TASK 32-42-27-000-001) and (Ref. AMM TASK 32-42-27-400-001) and reactivate the safety valve (2621GM).
2 If there are no leaks and if the fault continues:
_
- replace the SAFETY VALVE- ALTN BRK, WHEEL 4 (2621GM) (Ref. AMM TASK 32-43-16-000-001) and (Ref. AMM TASK 32-43-16-400-001).
(3) If the fault continues:
- replace the SERVOVALVE- ALT BRK,WHEEL 4 (42GG) (Ref. AMM TASK 32-43-27-000-001) and (Ref. AMM TASK 32-43-27-400-001).
