__________________
A. Do an operational test of the Normal braking system (Ref. AMM TASK 32-42-00-710-001). Make sure that the related pistons do not extend.
4. Fault Isolation
_______________
A. If the test confirms the fault:
- do a check of the related self-sealing coupling for correct condition.
(1) If not correct:
- connect it correctly.
(a) If the fault continues:
- replace the self-sealing coupling.
(2) If correct:
- replace the related BRAKE-WHEEL 2 (2641GM) or BRAKE-WHEEL 4 (2642GM) or BRAKE-WHEEL 1 (2643GM) or BRAKE-WHEEL 3 (2644GM) (Ref. AMM TASK 32-42-27-000-001) and (Ref. AMM TASK 32-42-27-400-001).
