Question

1. technician a says a thorough brake inspection can be performed by removing only two wheels, one front and one rear. technician b says inspecting the outside rotor surface is enough to tell whether the rotor should be replaced or not. who is correct?

○ technician a
○ technician b
○ both technician a and technician b
○ neither technician a nor technician b

Explanation:

To determine who is correct, we analyze each technician's statement:

• Technician A: A thorough brake inspection typically requires checking all brake components (pads, rotors, calipers, etc.) on all wheels. Removing only one front and one rear wheel is insufficient, as other wheels’ brakes (and internal rotor surfaces, hidden components) may have issues.
• Technician B: Rotor replacement decisions require inspecting both the outside and inside rotor surfaces (for warping, thickness, cracks, etc.). Inspecting only the outside is not enough.

Since both statements are incorrect, neither Technician A nor Technician B is correct.

Answer:

D. Neither Technician A nor Technician B
