Aircraft Brakes Flashcards
Types of brakes
- Speed brakes
- Flaps and spoilers
- Some propellers
- Thrust reverses
- Wheel brakes
Brakes turn ________ into ________?
Kinetic energy into heat energy
Energizing drum brakes (servo brakes)
The turning of the brake drum causes the brake shoes to wedge themselves tighter and increases braking
Hydraulic actuator
pushes the shoes into the drum to start the braking process
Hydraulic actuator
Pushes the shoes into the drum to start the braking process
Retracting springs
Pull the shoes off when brake pressure is released
Non-energizing brakes
-A brake that does not use the momentum of the aircraft to increase friction
-Uses only hydraulic activation and braking deepens on hydraulic pressure
Brake maintenance consist of
-Inspecting
-Testing
-Bleeding
-Replacing
Type of brake systems
Mechanical or hydraulic
Drum or disk
Single and double servo
Single disk and Multiple disk
Dual and Single hydraulic system
What is an expander tube brake
An expander tube pressurized by hydraulic fluid pushes against brake blocks
Components of brakes disc
-caliper
-pads
-torque plate
-bleeder fitting
Two methods of brake bleeding
- Gravity up-down bleeding
- Power down-up bleeding
Components of brake system
-Reservoir
-Master cylinder
-Plumbing
-Slave cylinder
Boosted brakes
Add additional braking pressure to the fluid if needed
Brake deboosters
Reduce brake pressure to a usable pressure
