Question

two technicians are discussing the correct procedure for cleaning a rotor after machining. technician a says that soap and water is the best way to remove all of the metal debris from the rotors surface. technician b says not to use brake cleaner because it may actually freeze the tiny metal particles to the rotors surface, which may lead to brake noise. who is correct?
technician a
technician b
both technician a and technician b
neither technician a nor technician b

Explanation:

Soap and water is not the best way to remove metal debris as it may leave residues and not effectively remove all debris. Brake - cleaner is a common and effective way to clean rotors and does not freeze metal particles to the surface. So both technicians are wrong.

Answer:

Neither Technician A nor Technician B
