Primary and Secondary Air Pressure Gauges

c2 dm 18.05.004

Warning: If air pressure falls below minimum pressure, the braking ability of the vehicle will be limited. Slow the vehicle down and bring it to a gradual stop. Do not attempt to move the vehicle until air pressure has risen above the minimum level. Moving a vehicle without adequate braking power could cause an accident resulting in property damage, personal injury, or death.

Air pressure gauges register the pressure in the primary and secondary air systems. Normal pressure with the motor running is 100 to 120 psi (690 to 827 kPa) in both systems. See Fig..
