InspectionPregunta 32 de 60
For a single vehicle (straight truck), what is the maximum allowable air pressure loss in one minute with the brakes applied?
a.1 psi
b.3 psi
c.6 psi
d.10 psi
Explicación
For a single vehicle, air pressure should not drop more than 3 psi in one minute when the brakes are fully applied and the engine is off. For a combination vehicle, the limit is 4 psi in one minute. A larger loss indicates a leak too big to be safe.
