 3. Fault Confirmation
__________________
 A. Test
 (1) Do a check to confirm that the left brake pedal is pushed with little or no resistance.
 4. Fault Isolation
_______________
 A. If the test confirms the fault:
 - do a check and repair, if necessary, the mechanical link between the pedal and the left master cylinder (2625GM).
 (1) If the fault continues:
 - do a check and repair, if necessary, the hydraulic line between the left master cylinder (2625GM) and the Alternate-brake distribution dual-valve (2577GM).

 - bleed the Low Pressure Control System of the Alternate braking (Ref. AMM TASK 32-43-00-612-001)

 (2) If the fault continues:

 - bleed the Alternate Braking System (Ref. AMM TASK 32-43-00-870-002).

 (3) If the fault continues:

 - replace the MASTER CYL-BRK CTL,L (2625GM) (Ref. AMM TASK 32-43-12-000-001) and (Ref. AMM TASK 32-43-12-400-001).

 (4) If the fault continues:

 - replace the DUAL VALVE-ALTN BRK DISTR (2577GM) (Ref. AMM TASK 32-43-14-000-001) and (Ref. AMM TASK 32-43-14-400-001).

 3. Fault Confirmation
__________________
 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 there is no pressure on the two sides (RH & LH) of the triple indicator.

 4. Fault Isolation
_______________
 A. If the test confirms the fault
 - check for leaks on the: . hydraulic line between the automatic selector (2576GM) and the parking-brake operated valve (2579GM) . hydraulic line between the parking-brake operated valve (2579GM) and the alternate-brake distribution dual valve (2577GM).
 (1) If there are leaks:
 - repair the related hydraulic line.
