Loose

Tight

Cracked

The parking brake should be applied every time you park your vehicle.

4 . Air pressure should build up in a single air system within:

15 minutes.

12 minutes.

Three minutes.

In single air systems, air pressure should build from approximately 50 to 90 psi within three minutes.

5 . Vehicles with dual air brake systems:

Maintain full-capacity air pressure in the braking systems even when the vehicle is not running.

Maintain some air pressure in the braking systems when the vehicle is not running.

Must be run to build enough air pressure to brakes to operate properly.

Do not need time to build air pressure before a trip.

Before driving a vehicle with a dual air brake system, you must allow the air compressor time to build up at least 100 psi of air pressure in both the primary and secondary systems.

6 . If the brake pads rub against the brake drums and create too much heat:

The brakes will stick.

The brakes will become extra sensitive.
