Question 16 of 25
Score: 0/0If your vehicle has a properly working dual air brake system and minimum-sized air tanks, how long should it take for air pressure to build from 85 to 100 psi?
ExplanationIn a properly functioning system, air pressure should rise from 85 to 100 psi within 45 seconds. A slower buildup may indicate a problem with the air compressor or system leaks.
