7 . The leakage rate for a single vehicle with air brakes should be no more than ____ in one minute during a static leakage test.

When performing a static leakage test on a single vehicle with air brakes, the leakage rate should be no more than 2 psi in a minute. If the air leaks from the air brake system at a quicker rate, the vehicle should not be driven because something likely needs to be repaired.

A dual air brake system is made up of two separate air brake systems. If there is an air leak in one system, it may not affect the other.

When braking at a speed of 55 mph while driving on dry pavement, the brake lag can add around 32 feet to the vehicle's total stopping distance.
