3. Fault Confirmation
Subtask 32-43-00-710-050-A ** ON A/C NOT FOR ALL

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

4. Fault Isolation
Subtask 32-43-00-810-054-A ** ON A/C NOT FOR ALL

A. If the test confirms the fault:

do a check of the fluid level of the brake-control hydraulic reservoir (2624GM) AMM 32-43-11-210-001.

(1) Do a check for an external hydraulic leak of the brake-control hydraulic reservoir (2624GM).
(a) if there is a leak:

(2) If there is not leak:

do a check and repair, if necessary, the leak of the hydraulic line between the brake-control hydraulic reservoir (2624GM) and the master cylinder (2625GM or 2626GM).
bleed the Low Pressure Control System of the Alternate braking AMM 32-43-00-612-001.
