8306. What would be the effect if the piston return spring broke in a brake master cylinder?
The brakes would drag
8307. In brake service work, the term "bleeding brakes" is the process of
withdrawing fluid form the system for the purpose of removing air that has entered the system
8309. 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
air in the brake hydraulic system
8310. Aside form an external leak in the line, what will cause parking bnrake s to dcontimually bleed off pressure?
An internal leak in the master cylinder
8315. The braking action of a Cleveland disk brake is accomplishe by compressing a rotating brake disk between two opposite brake linings. How is equal pressure on both side of the rotating disk assured
By allowing the caliper ot flat to automatically equalize as pressure is applied to the rotor
8316. If it is determined that spongy brake action is not caused by air in the brake system, what is the next most likely cause?
deteriorated flexible hoses
8317. Many brake types can be adapted to operate mechanically or hydraulically. Which type is not adaptable to mechanical operation?
8318. A brake debooster valve is installed in systems where the high pressure of the gydraulic system is used to operate brakes
that are designed to work with lower pressure
8320. When leeding aircraft brakes, on of the indications that the air has been purged form the system is
firm brake pedals
8322. Debooster valves are used in brake systems primarily to
rduce the pressure and release the brake s rapidly
8326. power boost brake systems are used on aircraft that have
high landing speeds
8331. Aircraft brake srequiring a large volume of fluid to operated the brakes generally
use power brake control valves
8332. What is one effect a restricted compenasator port of a master cylinder will have on a brake system?
The restriction will cause sllow release of the brakes
8334. Internal leakage in a brake master cylinder unit can cause
the pedal to slowly creep down while the pedal pressure is applied
8337. The pressure source for power brakes is
the main hydraulic system
8338. Which statement is true with respect to an aircraft wquipped with hydraulically operated mulitple- disk type brake assemblies?
Do not set parking brake wihen brakes are hot
8339. 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?
a shuttle valve
8342. The purpose of a relief valve in a brake system is to
compensate for thermal expansion
8345. What is the purpose of a compensation port or valve in a brake master cylinder of an independent brake system?
permits the fluid to flow toward or away from the reservoir as temperature changes
8349. Debooster cylinders are used in brake systems primarily to
reduce the pressure to the brake and increase the volume of fluid flow
8352. If an airplane equipped with master cylinders and single-disk brakes has excerssive brake pedal travel, but the vrakes are hard and effecxtive, the problable cause is
worn brake linings
8355. How can it be determined that all air has been purged form a master cylinder brake system?
by noting whether the brake is firm or spongy
8356. The left brake is dragging excessively on an airplane on which no recent brake service work has been performed, the most probable cause is
foreign particles stuck in the master cylinder compensating port
8357. if a brake debooster is used in a hydraulic brake system, its position in the system will be
between the brake control valve and the brake acutation cylinder
8371. A pilot reports that the brake pedals have excessive travel. a probable cause is
