Air Brake Basics
The primary purpose of this system is to use compressed air to apply pressure to the brakes, causing the vehicle to slow down or stop.
What is an air brake system?
This component in an air brake system converts compressed air into mechanical force to apply the brakes.
What is a brake chamber?
This is used to control the actuation of the service brakes during driving operations
What is the treadle valve?
This abbreviation stands for Anti-lock Braking System.
What is ABS?
These types of vehicles typically use air brakes.
What are large commercial vehicles such as trucks, buses, and trailers?
This component removes moisture and contaminants from the compressed air in an air brake system.
What is an air dryer?
this component in the supply system collects any extra oil or water that is made from the compressor
What is the supply or wet tank?
This system enhances vehicle safety by preventing wheel lock-up during braking.
What is ABS?
This component generates the compressed air used in an air brake system.
What is the air compressor?
This component maintains the correct distance between the brake shoes and the brake drum in an air brake system.
What is a slack adjuster?
this component is relayed to control the parking brakes release faster?
What is the quick release valve?
In modern vehicles, ABS is now being used for this additional function to help prevent rollovers and improve vehicle stability.
What is Automatic Traction Control (ATC)?
This component regulates the cut-in and cut-out pressures of the air compressor.
What is the air governor?
These components were made mandatory on new commercial vehicles in the U.S. in 1994.
What are automatic slack adjusters?
This component is used by the operator before the machine can be moved.
What is the parking brake release valve?
This component directs air pressure from the reservoirs to the brake chambers to apply the brakes.
What is a relay valve?
These brakes are considered more reliable than hydraulic brakes for heavy-duty vehicles because they provide consistent braking power, are self-adjusting, and can handle heavy loads.
What are air brakes?
This component has both the service and the emergency brake built together in one unit
What is a double acting brake chamber?
this componet will turn off when the system sees 60 PSI.
What is the low pressure indicator?
This component converts rotational force into linear force in an air brake system.
What is an S-cam?
