A. Do an operational test of the Normal braking system AMM 32-42-00-710-001.
Make sure that the related pistons do not extend.
4. Fault IsolationMake sure that the related pistons do not extend.
Subtask 32-42-00-810-105-A
A. If the test confirms the fault:
- do a check of the related self-sealing coupling for correct condition.
- connect it correctly.
- replace the self-sealing coupling .
- replace the related BRAKE-WHEEL 2 [2641GM] or BRAKE-WHEEL 4 [2642GM] or BRAKE-WHEEL 1 [2643GM] or BRAKE-WHEEL 3 [2644GM] AMM 32-42-27-000-001 and AMM 32-42-27-400-001.
