3. Fault Confirmation
Subtask 32-43-00-710-052-A ** ON A/C NOT FOR ALL

A. Test
(1) Do a check to confirm that the left brake pedal is pushed with little or no resistance.

4. Fault Isolation
Subtask 32-43-00-810-056-A ** ON A/C NOT FOR ALL

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 AMM 32-43-00-612-001

(2) If the fault continues:

(3) If the fault continues:

replace the DUAL VALVE-ALTN BRK DISTR [2577GM] AMM 32-43-14-000-001 and AMM 32-43-14-400-001.
