Answer

Brief Explanations:

To determine the correct technician, we analyze their statements:

  • Technician A: Grinding noise in drum brakes typically requires replacing brake shoes and resurfacing/replacing drums. This aligns with standard drum brake repair (grinding often signals worn shoes/damaged drums).
  • Technician B: Click noise in drum brakes requires replacing brake shoes and resurfacing/replacing drums. However, click noises in drum brakes are more commonly linked to issues like loose hardware or misaligned components, not the same repair as grinding (which involves shoe/drum wear). Thus, Technician A’s statement is correct, while Technician B’s is not.

Answer:

a. Technician A
