- do a check and repair if necessary the hydraulic line between the master cylinders and the Alternate-brake distribution dual-valve (2577GM).
(2) If the fault continues:
- do a filling and bleeding of the low pressure control system of the Alternate brakin (Ref. AMM TASK 32-43-00-612-001).
(3) If the fault continues:
- replace the MASTER CYL-BRK CTL,L (2625GM)
or the MASTER CYL-BRK CTL,R (2626GM)
(Ref. AMM TASK 32-43-12-000-001)
(Ref. AMM TASK 32-43-12-400-001).
(4) If the fault continues only on the Normal braking system:
- do a check and repair if necessary the mechanical link that operates the brake pedal position transmitter.
(5) If the fault continues only on the Alternate braking system:
- replace the DUAL VALVE-ALTN BRK DISTR (2577GM) (Ref. AMM TASK 32-43-14-000-001) (Ref. AMM TASK 32-43-14-400-001).
(a) If the fault continues:
- replace the DUAL SHUTTLE VALVE-BRK YELLOW PRESS (2578GM) (Ref. AMM TASK 32-45-16-000-001) (Ref. AMM TASK 32-45-16-400-001).
(6) If the fault continues on the two braking systems:
- do a check for a message related to the brake systems on the POST FLIGHT REPORT (PFR) and if necessary refer to the 32-42-00, Page Block 101.
B. If the difference of average temperature between the L and R gears is less than 150.C:
- no action is necessary.
C. Do the tests given in Para. 3.A.
