The brake pedal transmitter unit transforms the pedal
input into four identical electrical voltages per side
which are sent to the BSCU for selector valve
energization.
Any overtravel is absorbed by the spring rods which
actuate the levers of the transmitter unit.

DESCRIPTION
Brake belts stop the nose gear wheels at the end of
the gear retraction cycle.
NOTE: Depending on the aircraft configuration, brake
bands are removed and optionally re-installed.
When removed, there will be no braking of the
nose wheels which shall be allowed to spin down
naturally.

HYDRAULIC RESERVOIR
IDENTIFICATION
FIN: 2624GM
LOCATION
ZONE: 122
DESCRIPTION
The brake control hydraulic reservoir supplies the
master cylinders of the alternate system with hydraulic
fluid to permit volume changes of the fluid and
compensate possible leakages.
The reservoir is slightly pressurized by a spring
loaded piston: 22 psi (1,5 bar).
Capacity: 3.05 cu. in. (50 cm3).
MASTER CYLINDERS
IDENTIFICATION
FIN: 2625GM (LH), 2626GM (RH)
LOCATION
ZONE: 122
DESCRIPTION
There is one master cylinder for the LH side and one
for the RH side.
They are used to control the distribution dual valve
of the alternate brake system by displacement of fluid.
They also give artificial feel at the pedals by means
of an internal spring and the load resulting from the
pressure increase in the control circuit.

ALTERNATE DUAL VALVE
IDENTIFICATION
FIN: 2577GM
LOCATION
ZONE: 148
DESCRIPTION
The alternate dual valve includes two independent
pressure-reducing valves, one for each main gear.
A master cylinder operates each valve.
A transparent drain tube connected to the cover of the
dual valve is used to check for possible presence of
water.
