Question

question 1-16
technician a says that a faulty vacuum booster can affect engine operation. technician b says that steel brake line can be replaced with a copper line since it is easier to bend that material into shape. which one is correct?
○ technician a
○ technician b
○ both technician a and technician b are correct
○ neither technician is correct

Explanation:

A faulty vacuum booster does impact engine operation (Technician A is correct). Steel brake lines are not replaced with copper (copper is not suitable for brake lines due to pressure and corrosion issues, so Technician B is incorrect). So only Technician A is correct.

Answer:

A. Technician A
