InspectionQuestion 40 of 60
During the pre-trip air brake check, when should you check that the pushrod stroke is not too long?
a.Only after the trip is finished
b.While inspecting the brake chambers and slack adjusters, since too long a stroke means brakes are out of adjustment
c.Only when the engine is off and cold
d.Never, because it cannot be checked
Explanation
When brakes are applied, the pushrod should not travel too far out of the brake chamber. Excessive pushrod stroke means the brakes are out of adjustment and may not stop the vehicle effectively. This is related to checking slack adjusters and is a common out-of-service violation.
