What is the purpose of the automatic adjusters in a multiple disk brake assembly?

Eliminates the need for manual adjustments and compensates for disc wear

A brake system using a floating rotor disk has a floating type caliper. True or False?

It is necessary to remove the wheel in order to facilitate the removal of a floating type brake caliper. True or False?

False

When bleeding brakes by the gravity method, the pressure pot hydraulic fluid is introduced into the system through the brake caliper. True or False?

False

Power brakes utilize hydraulic pressure from what aircraft system?

Main hydraulic system

What are the three main components of an antiskid brake control system?

Skid control generator, antiskid control valve, skid control box

What is the purpose of a debooster in a hydraulic brake system?

To reduce pressure in a high pressure system to within a working range of the brake assembly and to increase the volume of fluid flow

What is the purpose of bleeding brakes?

To remove the air

What are the two methods of bleeding aircraft brakes?

Top down gravity bleeding, bottom up pressure bleeding

Aircraft brakes must be able to withstand tremendous amounts of heat when they convert the kinetic energy of the aircraft into heat during the deceleration of the aircraft. True or False?

True

Brake lining glazing is caused by improper application of the brakes by the pilot. True or False?

True

Brake linings can be replaced without the total re-manufacture of the brake assembly. True or False?

True

Spongy brakes are an indication of what problem in a brake system?

air in the system

Lockout deboosters are primarily pressure reducing valves that A. allow full debooster piston travel without fluid from the high pressure side entering the low pressure chamber B. cannot allow full debooster piston travel without fluid from the high pressure side entering the low pressure chamber C. must be bled separately after brake bleeding has been completed

allow full debooster piston travel without fluid from the high pressure side entering the low pressure chamber

The purpose of a relief valve in a brake system is to A. reduce pressure for brake application B. prevent the tire from skidding C. compensate for thermal expansion

compensate for thermal expansion

Which statement is true with respect to an aircraft equipped with hydraulically operated multiple disc type brake assemblies? A. there are no minimum or maximum disc clearance checks required due to the use of self compensating cylinder assemblies B. do not set parking brake when brakes are hot C. no parking brake provisions are possible for this type of brake assembly

do not set parking brake when brakes are hot

The pressure source for power brakes is A. the main hydraulic system B. the power brake reservoir C. a master cylinder

the main hydraulic system

Debooster valves are used in brake systems primarily to A. ensure rapid application and release of the brakes B. reduce brake pressure and maintain static pressure C. reduce the pressure and release the brakes rapidly

reduce the pressure and release the brakes rapidly

Debooster cylinders are used in brake systems primarily to A. reduce brake pressure and maintain static pressure B. relieve excessive fluid and ensure a positive release C. reduce the pressure to the brake and increase the volume of the fluid flow

reduce the pressure to the brake and increase the volume of the fluid flow

Aircraft brakes requiring a large volume of fluid to operate the brakes generally A. use independent master cylinder systems B. do not use brake system accumulators C. use power brake control valves

use power brake control valves

In brake service work, the term "bleeding brake" is the process of A. withdrawing air only from the system B. withdrawing fluid from the system for the purpose of removing air that has entered the system C. replacing small amounts of fluid in reservoir

withdrawing fluid from the system for the purpose of removing air that has entered the system
