Where is the disc brake assembly located on the aircraft? |
Bolted to the torque flange of each main landing gear shock strut |
|
|
When the disc brake is in the OFF position, what forces the piston away from the rotating disc? |
The compressed return spring |
|
|
When the disc brake is in the ON position, what forces the piston toward the rotating disc? |
Fluid pressure |
|
|
When the automatic adjuster is in operation, the pins will move a distance equal to what? |
Lining wear |
|
|
What is the difference between a single disc and a dual disc brake? |
Because the dual disc brake utilizes two rotating discs, the u-throat is wider. A center carrier is installed between the two rotating discs and is free to move sideways in the u-throat, but is prevented from rotating by bolts passing through the housing |
|
|
What maintenance is required of a disc brake when minimum allowable adjuster pin is showing? |
New brake linings must be installed |
|
|
What does the cylinder head do? |
Closes the cavity |
|
|
What does the rotating disc do? |
The only rotating part of the brake |
|
|
What does the adjusting pin do? |
a steel pin fits down into the inside of the piston |
|
|
What is the housing made of? |
may be cast or divided |
|
|
what is the purpose of the fluid ports and bleed screws? |
one on each side of the housing, enabling the brake to be used on either side of the aircraft |
|
|
what does the piston return spring do? |
returns the piston to the OFF position |
|
|
what does the anvil do? |
stops all lateral movement |
|
|
what does the spring retainer do? |
encloses the return spring within the piston |
|
|
what does the brake lining do? |
they are flat, circular discs made of heat and wear resistant composition , impregnated with brass particles |
|
|
where is the center carrier located? |
mounted between the rotating discs |
|
|
what does the retaining ring do? |
secures the spring retainer to the piston |
|
|
what is the piston? |
it is a cup shaped and fits into each cylinder cavity |
|
|
what are the cavities? |
cylinder bores in which the piston assemblies operate |
