1 . Spring brakes come on:

When the brakes are noisy. Spring brakes come on automatically when air pressure drops to an unsafe psi level. Instead of waiting for the spring brakes to automatically activate, you should safely exit the road as soon as you notice the low pressure warning signal and bring your vehicle to a stop while you are still able to control the brakes.

2 . A low air pressure warning signal:

Any vehicle with air brakes must be equipped with a low air pressure warning signal.

3 . Service brakes should:

Before driving, you should always verify that your service brakes are in good working order. Testing the brakes before a trip allows you to locate any problems before you need to brake while on the road.

4 . Using the brakes creates heat. If too much heat is produced:

Brakes are designed to take a lot of heat, but drivers should not rely solely on the brakes to slow their vehicle. Brakes may fade and lose their ability to slow down the vehicle if they become too hot, so drivers should also rely on the engine braking effect.

5 . What tells you how much pressure is in your vehicle's air tanks?

A vehicle that is equipped with air brakes must also be equipped with a supply pressure gauge. This gauge tells the driver how much air pressure is in each of the vehicle's air tanks.

6 . Foundation brakes are used:

Foundation brakes are used on each wheel of a CMV. The most common type of foundation brake is the s-cam drum brake.
