Replace Brake Linings Flashcards
Where can you find a list of brake fluids approved for the aircraft?
In the aircraft service manual
What is used to flush brake lines and cylinders if the system uses vegetable base fluid?
Alcohol
What is used to flush brake lines and cylinders if the system uses mineral-base fluid?
Naphtha, varsol, or stoddard solvent
How do you measure the amount of brake lining wear on single disk brakes?
Measure the clearance between the disk and the inboard side of the brake housing with the brakes applied
What is the purpose of the debooster in a hydraulic power brake system?
The debooster decreases the pressure and increases the volume of fluid going to the brakes. This gives the pilot better control of the brakes
What should be done to hydraulic brakes when the pedal has spongy feel?
The spongy feel is caused by air in the brake. The brakes should be bleed of this air
What is the purpose of the compensator port in the master cylinder of aircraft brakes?
The compensator port in the master cylinder opens the brake resevoir to the wheel cylinders when the brakes are off. This prevents pressure from building up in the brake lines and causing the brakes to drag
What is the purpose of the shuttle valve in the brake system of an aircraft using hydraulic power brakes?
The shuttle valve is an automatic transfer valve. It allows the brakes to be operated by hydraulic system pressure under all normal conditions; but if this pressure is lost, it allows the brakes to be operated by the emergency backup system
How does an anti skid brake system keep the wheels of an aircraft from skidding on a wet runway?
The anti skid system monitors the rate of deceleration of the wheels. If any wheels slows down faster than it should (as it would at the beginning of a skid), the pressure on the brake in that wheel is released until the wheel stops decelerating, then the pressure is reapplied
