Landing gear chapter 9 section B test
That are designed to work with lower pressure
A brake debooster valve is installed in system where the high pressure of the hydraulic system(3,000 PSI) is used to operate brakes...
Brake rotors have worn
A pilot reports that the brake pedals have excessive travel. A probable cause is....
Air in the brake hydraulic system
A pilot reports the right brake on an aircraft is spongy when the brake pedal is depressed in a normal manner. The probable cause is.......
Reduce the pressure & release the brake rapidly
Debooster valves are used in brake system primarily to...
Allow full debooster piston travel without fluid from the high pressure side entering the low pressure chamber
Lockout debooster are primarily pressure reducing valves that....
Compensate for thermal expansion
The purpose of a relief valve in a brake system is to....
The restriction will cause slow release of the brakes
What is one effect a restricted compensator port of a master cylinder will have on a brake system?
C. Do not set parking brake when brakes are hot
Which statement is true with respect to an aircraft equipped with hydraulically operated multiple disk type brake assemblies? A. There are no minimum or maximum disk clearance checks required due to the use of self compensating cylinder assemblies. B. No parking brake provisions are possible for this type of brakes assembly. C. Do not set parking brake when brakes are hot.
Reduce the pressure to the brake & increase the volume of fluid flow
Debooster cylinders are used in brake systems primarily to.....
Worn brake lining
If it is determined that spongy brakes action is not caused by air in the brake system, what is the next most likely cause?
Withdrawing fluid from the system for the purpose of removing air that has entered the system
In brake service, the term "bleeding brakes" is the process of.....
The pedal to slowly creep down while pedal pressure is applied
Internal leakage in a brake master cylinder unit can cause.....
More than one brake assembly per axle
Power boost brake systems are used on aircraft the have.....
By allowing the caliper to float to automatically equalize as pressure is applied to the rotor
The braking action of a Cleveland disk brake is accomplished by compressing a rotating brake disk between two opposite brake lines. How is equal pressure on both sides of the rotating disk assured?
Foreign particles stuck in the master cylinder compensating port
The left brake is dragging excessively on an airplane on which no recent brake service work has been performed. The most probable cause is.....
The main hydraulic system
The pressure source for power brakes is .....
Preventive maintenance
The removal, installation, & repair of landing gear tires by the holder of a private pilot certificate on an aircraft the pilot owns or operates is considered to be.....
Permits the fluid to flow toward or away from the reservoir as temperature changes
What is the purpose of a compensating port or valve in a brake master cylinder of an independent brake system?
A shuttle valve
What type of valve is used in the brake actuating line to isolate the emergency brake system from the normal power brake control valve system?
The brake would drag
What would be the effect if the piston return spring broke in a brake master cylinder?
Firm brake pedals
When bleeding aircraft brakes, one of the indications that the air has been purged from the system is......
Use power brake control valves
Aircraft brakes requiring a large volume of fluid to operate the brakes generally....
An internal leak in the master cylinder
Aside from an external leak in the line, what will cause parking brakes to creep continually to the OFF position?
By noting whether the brake is firm or spongy
How can it be determined that all air has been purged from a master cylinder brake system?
Between the brake control valve & the brake actuating cylinder
If a brake debooster is used in a hydraulic brake system, its position in the system will be...
