With the engine off and brakes released, what is the maximum allowable air leakage per minute for a straight truck?
a.1 psi
b.3 psi
c.2 psi
d.5 psi
Explicación
With the engine off, the air pressure should not drop more than 2 psi in one minute for a single vehicle with the brakes released. For a combination vehicle, the limit is 3 psi per minute. Excessive leakage means the system cannot hold pressure and must be repaired.
