What are two standard main reservoir pressures for the operation of a vehicles air brakes? The operating pressure range for vehicle air brake systems must be between 552 kPa and 1000 kPa (80 psi and 145 psi ). How fast should a semi build air pressure? Air pressure build-up from 85 psi to 100 psi should take 45 seconds or less. While driving, observe the air pressure gauge during build-up to ensure proper air system operation. braking, pull over at a safe place and perform the 2 minute / 5 psi leakage test. What is the difference between primary and...
