Landing Gear Systems Quiz #6

How can it be determined that all air has been purged from a master cylinder brake system? A. by operating a hydraulic unit and watching the system pressure gauge for smooth, full scale deflection B. by noting whether the brake is firm or spongy C. by noting the amount of fluid return to the master cylinder upon brake release

by noting whether the brake is firm or spongy

What would be the effect if the piston return spring broke in a brake master cylinder? A. the brakes would become spongy B. the brake travel would become excessive C. the brakes would drag

the brakes would drag

Internal leakage in a brake master cylinder unit can cause A. slow release of brakes B. the pedal to slowly creep down while pedal pressure is applied C. fading brakes

the pedal to slowly creep down while pedal pressure is applied

What is one effect a restricted compensator port of a master cylinder will have on a brake system? A. the brakes will operate normally B. the reservoir will be filled by reverse flow C. the restriction will cause slow release of the brakes

the restriction will cause slow release of the brakes

Independent type brake systems utilize --- master cylinders

two

General aviation aircraft utilize the --- master cylinder and its variations.

vertical

Cleveland brake assemblies have the disc mounted ---.

solid to the wheel

List the five main manufacturers of current brake systems in use today:

Goodrich, Goodyear, Cleveland, Dunlap, Musier-Bugatti

If it is determined that spongy brake action is not caused by air in the brake system, what is the next most likely cause? A. work brake linings B. internal leakage in the master cylinder C. deteriorated flexible hoses

deteriorated flexible hoses

Many brake types can be adapted to operate mechanically or hydraulically. Which type is not adaptable to mechanical operation? A. single disc spot type B. single servo type C. expander tube type

expander tube type

Goodyear master cylinders get their fluid from an --- ---.

external reservoir

Small aircraft utilize the --- type brake system

independent

Goodyear has the brake housing attached solidly to the --- --- -- flange with mounting bolts

landing gear axle

What is the purpose of a compensating port or valve in a brake master cylinder of an independent brake system? A. assists in the master cylinder piston return B. prevents fluid from flowing back to the reservoir C. permits the fluid to flow toward or away from the reservoir as temperature changes

permits the fluid to flow toward or away from the reservoir as temperature changes

The first thing to check if the master cylinder has excessive travel is:

reservoir fluid level

Brake assemblies commonly used on aircraft are the: --- Disc --- Disc --- Disc --- --- types

single, dual, multiple, segmented rotor

The --- and --- disc types are commonly used on --- ---.

single, dual, small aircraft

If an airplane equipped with master cylinders and single disc brakes has excessive brake pedal travel, but the brakes are hard and effective, the probable cause is: A. the master cylinder one way cup is leaking B. worn brake linings C. worn brake disc causing excessive clearance between the notches on the perimeter of the disc and the splines or keys on the wheel

worn brake linings
