Definitions:

Brake Fade

Caused by a number of factors mostly relating to reduction in the coefficient of friction of brake friction materials. Thermal expansion of brake drums under prolonged braking tends to enlarge drum diameters, meaning that the actuation mechanisms such as slack adjusters no longer function at optimum mechanical efficiency, which makes brake fade more of a problem in drum brake systems.

Safety Pop-Off Valves

Valves designed to release pressure automatically to prevent damage or explosions in pressurized systems.

System Supply Tank

A reservoir or tank that holds fluid or fuel integral to the operation of a system, ensuring there is a sufficient supply for its functioning.

Compressor Unloader Circuit

A system within an air compressor that reduces load and pressure by allowing compressed air to bypass during start-up or when the desired pressure is reached.
