R **ON A/C 001-049, 051-099, 101-149, 151-199, 201-299,
 A. If the difference of temperature between the two brakes on a same gear is more than 150.C and either the temperature of one brake is more than 600.C or the temperature of one brake is less than 60.C:
 - do a check for a message related to the braking system on the POST FLIGHT REPORT (PFR).
 (1) If there is a message:

 - you can find the related trouble shooting procedure in the 32 fault symptoms Page Block 101.

 (2) If there is no message:

 - do a check of the related self-sealing coupling connection.

 - do the bleeding of the corresponding brake system at the brake units (Ref. AMM TASK 32-42-00-870-001) or (Ref. AMM TASK 32-43-00-870-002)

 - do an inspection/check of the brake unit for leaks and damage. (Ref. AMM TASK 32-42-27-210-006)

 (a) if necessary replace the BRAKE-WHEEL 2 (2641GM) or BRAKE-WHEEL 4 (2642GM) or BRAKE-WHEEL 1 (2643GM) or BRAKE-WHEEL 3 (2644GM) (Ref. AMM TASK 32-42-27-000-001) (Ref. AMM TASK 32-42-27-400-001)

 (b) if there are no leak or damage:

 - refer to (Ref. TSM TASK 32-48-00-810-801) if brake fans are installed.

 (3) If the inspections are correct:

 - replace the SAFETY VALVE-NORM BRK, WHEEL 2 (2616GM) or SAFETY VALVE-NORM BRK, WHEEL 3 (2617GM) or SAFETY VALVE-NORM BRK, WHEEL 1 (2618GM) or SAFETY VALVE-NORM BRK, WHEEL 4 (2619GM) (Ref.

 (4) If the fault continues:

 - replace the PRESS XDCR-NORM BRK WHEEL 1 (11GG) or PRESS XDCR-NORM BRK WHEEL 3 (12GG) or PRESS XDCR-NORM BRK WHEEL 2 (13GG) or PRESS XDCR-NORM BRK WHEEL 4 (14GG) (Ref. AMM TASK 32-42-21-000-001) (Ref. AMM TASK 32-42-21-400-001)

 (5) If the fault continues:

 - do an inspection of the drive assy of the related tachometer
 (a) If the tachometer drive is damaged:

 - replace the related drive assy-tachometer (Ref. AMM TASK 32-42-68-000-003) (Ref. AMM TASK 32-42-68-400-003)

 (b) If the tachometer drive is not damaged:

 - replace the related TACHOMETER (Ref. AMM TASK 32-42-57-000-001) (Ref. AMM TASK 32-42-57-400-001)

 (6) If the fault continues:

 - replaced the related NORMAL SERVO-VALVE (Ref. AMM TASK 32-42-48-000-001) (Ref. AMM TASK 32-42-48-400-001)
