__________________
A. Test
(1) Do the operational test of the brake cooling system (Ref. AMM TASK 32-48-00-710-001).
(2) Make sure that the fan does not operate on the related brake.
4. Fault Isolation
_______________
A. If the test confirms the fault:
- do a check of the related impeller
(1) If the impeller is not OK:
- replace the impeller. (Ref. AMM TASK 32-48-51-000-002) and (Ref. AMM TASK 32-48-51-400-002)
