The application pressure gauge shows you how much pressure

Explanation:
The application pressure gauge shows the pressure being sent to the brakes when you apply the brake pedal. It tells you how hard you are braking, because it measures the brake line pressure that actuates the brake chambers. This is separate from the system pressure in the air tanks, and it’s not related to fuel or hydraulic systems. If the application pressure is low or doesn’t rise as you press the pedal, it can indicate a leak or a problem with the brake valve, which would affect braking performance.
