Airframe landing gear 8305-8343
The breaking action of a Cleveland disc brake is accomplished by compressing a rotating brake disc between two opposite brake linings how is equal pressure on both sides of the rotating disk assured
By allowing the caliper to float to automatically equalize pressure is applied to the rotor
When servicing an air oil shock strut with ML 5606 the strut should be
Collapsed and fluid added at the top of the filler opening
The purpose of a relief valve in a brake system is to
Compensate for thermal expansion
It is determined that spongy break action is not caused by air in the brake system what is the next most likely case
Deteriorating flexible hoses
Which statement is true with respect to an aircraft equipped with hydraulically operated multi disc type brake assemblies
Do not set parking brake when brakes are hot
Instructions concerning the type of fluid and amount of air pressure to be put in a shock strut are found
In the aircraft manufacturer service manual
An automatic dampening action occurs at the steering dampener if any reason the flow high-pressure fluid is removed from the
Inlet of the steering dampener
The repair for an out of tolerance Toe in condition of Main landing gear wheels determined not to be the result of bent or twisted components consist of
Inserting removing or changing the location of the washers or spacers at the center pivotal point of the scissor torque links
A sleeve spacer or bump ring is incorporated in the landing gear olio straight to
Limit the extension stroke
What is the purpose of the torque links attached to the cylinder and piston of a landing gear Oleo strut
Maintain correct wheel alignment
The primary purpose for balancing aircraft wheel assembly is two
Prevent heavy spots and reduce vibration
The removal installation and repair of landing gear tires by the holder of a private pilot certificate on an aircraft owned or operated is considered to be
Preventative maintenance
Debooster valves are used in brake system primarily to
Reduce the pressure and release the brakes rapidly
The metering pins in the olio shocks struts serve to
Retard the flow of oil as a stretcher compressed
What type of valve is used in the break actuating line to isolate the emergency brake system for the normal power brake control system
Shut off valve
A stripe or Mark applied to a wheel rim and extending into the sidewall of a tube tire is a
Slippage Mark
A brake debooster valve is installed in systems where the high pressure of a hydraulic system 3000 psi is used to operate brakes
That are designated to work with lower pressure
What action should be taken whenever maintenance is performed that will affect the landing gear system performance
The aircraft should be placed on jacks and a retraction test should be performed
What would be the effect if the piston return spring broke in a brake master cylinder
The brakes would drag
When an air oil type of landing gear shock strut is used the initial shock of landing is cushion by
The fluid being forced through a metered opening
The pressure source for power brakes is
The main hydraulic system
Internal leakage in a brake master cylinder unit can cause
The pedal to slowly creep down while pedal pressure is applied
What is one effect of a restricted compensator port of a master cylinder will have on a break system
The restriction will cause slow release of the brakes
Why do most aircraft tire manufacturers recommend that the tubes in newly installed tires be first be inflated then fully deflated and then re-inflated to correct pressure
To allow the tube to position itself correctly inside the tire
When working with high pressure high performance tires why is it recommended to deflate the tires on removing wheels from the axle
To ensure safety in case of a defective wheel or broken tire bolts
Aircraft brakes require a large volume of fluid to operate the brakes generally
Use power brake control valves
Overinflated aircraft tires made cause damage to the
Wheel flange
in brake service work the term bleeding brakes is the process of
Withdrawing fluid from the system for the purpose of removing air that has entered the system
To prevent a very rapid extension of the polio shock straight after initial compression resulting from landing impact
various types of valves or orifice are used which restrict the reverse fluid flow
A pilot reports the right break on aircraft is spongy when the right brake pedal is depressed in a normal manner the probable cause is
Air and the brake hydraulic system
Aside from external leak in the line what will cause parking brakes to continually bleed off pressure
An internal leak in the master cylinder
Aircraft tire pressure should be checked
At least once a week or more often
On an air valve core system what indicates high-pressure type
Embossed letter H
The purpose of a sequence valve in a hydraulic retractable landing gear is two
Ensure operation of the landing gear and gear doors is in proper order
Many brake types can be adapted to operate mechanically or hydraulically which type is not adaptable to mechanical operation
Expander tube type
On all aircraft equipped with retractable landing gear some means must be provided to
Extend the landing gear if the normal operating mechanism fails
When bleeding aircraft brakes one of the indications that air has been purged from the system is
Firm brake pedals
Exposure two and or storage near which of the following is considered harmful to aircraft tires
Fuel oil ozone electrical equipment hydraulic fluid and solvents
Power boost brake systems are used on aircraft that have
Highlanding speeds
