Brake system temperature monitoring system (Ref. 32-47-00)
The brake temperature system measures the temperature at each of the
four brakes
The sensor on each brake sends analog signals to the related BTMU.
The BTMU sends the signals to the BSCU.The BSCU changes the analog
data to ARINC data and sends it to the EIS.
The temperature values are shown on the lower ECAM DU.

Brake Cooling Fans (Ref. 32-48-00) (Optional)
The brake cooling fans permit high speed cooling of the brakes.They thus decrease the turnaround time of the aircraft if you make short flights with high energy braking.One fan is installed on each wheel of the main gear. A BRK FAN pushbutton switch is used to operate the fans.When the brakes are hot, the HOT legend of the pusbutton switch comes on.
(8)
Tire pressure indicating system (TPIS) (Ref. 32-49-00) (Optional)
The TPIS shows the pressure of the tires of the main gear and nose gear on the lower ECAM DU.
7. Operation/Control and Indicating________________________________
The BSCU (Ref. 32-42-00) includes hardware and software to:
-do a power-up test of parts of the system when the system is energized
-continuously monitor the system for failures
-keep a record of the failures
-send the failure data to the CFDS.
-
do specified tests of part of the system at specified times
-
do specified tests during ground maintenance.
For the description of these functions (Ref. 32-46-00).

Subtask 32-40-00-210-051
A. Check of the Brake System
(1)
Full check
(a)
Do a check of the attach and hinge fittings. Make sure that:
-
they are installed correctly,
-
they are safetied correctly (with the cotter pins, the tabwashers, the lockwashers and the lockwire),
-that the pins, the screws, the nuts and the washers do not show signs of corrosion.
(b)
Make sure that the identification labels are installed correctly.
(c)
Make sure that the bonding braids are in the correct condition.
(2)
Check of the hydraulic hoses
(a)
If a collar has a data which shows the month and the year of the limit of the life of the collar, examine this date and if it is expired you must replace the hose.
(b)
Make sure that the clamps have the correct diameter. Make sure that they are correctly installed and that they are in the correct condition. Make sure that the clamps are not worn because they are not installed correctly, because of the vibration or the pressure surge.
