Purpose
The brake shuttle valves select the highest of normal/autobrake
or alternate/gear retract pressures and sends it to the brakes.
Location
The brake shuttle valves are on the outboard sides of the ceiling
in the main landing gear wheel well.
Physical Description
The shuttle valves are un-biased valves with a shuttle piston
and a spring detent. The valves are interchangeable.
Functional Description
The shuttle piston moves to the detented position when a
pressure differential between the two input pressure source
lines increases to 80 psi or more. This connects the input line
with the highest metered pressure to the brake line. The shuttle
piston also blocks the line that has the lowest pressure.

General
The main landing gear wheel brakes use hydraulic pressure to
slow or stop the airplane during landing and taxi.
Location
Each wheel brake is on a main landing gear axle.
Physical Description
The brake assembly is a rotor-stator unit that operates using
hydraulic pressure. The assembly uses multiple steel discs as
rotors and stators.
Each main landing gear wheel brake has these components:
* Stators
* Rotors
* Pressure plate
* Piston/adjusters (6)
* Axle bushings
* Wear indicator pins (2)
* Brake hose connection/hydraulic bleed port.
Functional Description
The brake assembly has bushings. These bushings attach to
replaceable sleeves on the landing gear axle.
A torque takeout slot on the brake assembly aligns with a
torque pin on the bottom of the main landing gear inner
cylinder. The slot and pin transmit brake torque to the main
landing gear strut.
A retention cable connects both brakes together on each main
landing gear. The cable keeps the brake on the axle if the wheel
falls off the airplane.
Piston/adjuster assemblies apply brake system hydraulic
pressure to the pressure plate. The pressure plate forces the
stators and rotors together in the brake housing. This slows or
stops the wheel. The pistons automatically adjust for brake
wear.
Training Information Point
WARNING: MAKE SURE TO KEEP YOUR FINGERS AWAY
FROM THE PARTS OF THE BRAKE THAT CAN
MOVE DURING THE BLEED OPERATION.
INJURIES TO PERSONS CAN OCCUR.
CAUTION: BLEED THE BRAKE SYSTEM CORRECTLY. AIR IN
THE SYSTEM CAN MAKE THE BRAKES
UNSERVICEABLE. BRAKES WHICH ARE
UNSERVICEABLE CAN HAVE A FAILURE DURING
OPERATION.
CAUTION: DO NOT LET THE BRAKE UNIT WEAR UNTIL THE
RELINE INDICATOR PIN IS BELOW THE SURFACE.
DAMAGE TO EQUIPMENT CAN OCCUR.

Two indicator pins on the inboard side of the brake housing
show brake wear. You must apply the brakes to check the wear
indicator pins.
