Supply system
This component supplies pressurized air to the air reservoirs
What is the Compressor
This component takes are pressure and converts it into a mechanical movement
What is the Brake Chamber
When both the spring brake and service brake are applied simultaneously this is known as
What is compounding
This valve is allows for actuation of both Primary and Secondary air Brakes systems
What is the Dual Circuit Brake Vavle
This valve with engage the Spring Brakes as well as engage the trailer spring brakes when trailer is being towed and the valve is pulled out
What is the Park Control Valve
Known as the "brain of the operation" this component of the supply system is in control
what is the Governer
This component must complete three different jobs in order to be fully functional in an air brake system
What is the Slack adjuster
When compressor is in the loaded state, air pressure is not present at this location
What are the unloader valves
Keeping the Spring Brakes released when traveling down the highway is of utmost importance, this valve ensures this regardless of reservoir air pressure
What is the Supply double check Valve
Typically found on the supply/wet tank controls the maximum system Pressure
What is the Safety valve
What is Brake fade
In order to determine whether or not a compressor is functioning properly, a technician will conduct this test
What is Compressor Build time
Later replaced by a Ratio Valve and then ABS, this valve allowed for quick exhaust of secondary system air
What is the Quick Release Valve
If this Valve remains closed there will be no service signal air traveling backwards to the glad-hands
What is the Tractor Protection Vavle
What are air pressure gauges
If GVW of a vehicle is doubled the power required to stop is
What is doubled
The air drier is equipped with this in order to release moisture and contaminants out of the system
What is a purge valve
Found in the Primary brake system this valve is responsible for anti-compounding
What is the Spring Brake Relay Valve
Known commonly as the "Spike" this valve pulls from the Secondary system only when not included with a supply double check valve
What is the Trailer Brake Control Vavle
When the compressor is being rotated by the engine geartrain but no longer actively pumping air this is known as
What is unloaded state
Can be of the welded or bolted type this component supports and transfers braking forces
What is the spider
Most often found in the air drier and the automatic drain valve
What is a heater
When the Primary reservoir air supply has been exhausted this valve will allow for mechanical engagement of the spring brake chambers in a body loaded truck
What is the Spring Brake Valve
Prior to ABS, this valve allowed modulated foundation braking when a tractor unit was traveling down the road between loads
What is the Bobtailing Valve (Bobtailing Proportional Relay Valve)
