Question: 1 / 400

What is an emergency braking system in relation to air brakes?

A manual control for brake application

A system that requires the driver to activate brakes

A system that operates under loss of air pressure

An emergency braking system in relation to air brakes is specifically designed to function when there is a loss of air pressure. This is a critical safety feature because when the air pressure drops below a certain level, the standard braking system may not function properly. The emergency braking system activates automatically to ensure that the vehicle can still come to a stop, thus preventing potential accidents that could occur from brake failure.

This system utilizes spring-loaded brakes that engage when the air supply is lost, allowing the vehicle to brake even if normal brake operation is compromised. It's an essential component of air brake systems in commercial vehicles, enhancing safety by providing an additional layer of reliability in situations where air pressure may be insufficient.
