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

Explanation:

Ceramic brake - pads do not act as abrasives on brake rotors. They are designed to be less abrasive and provide quieter operation and longer - rotor life. Semi - metallic brake pads do not act as adhesives on brake rotors. They work by friction to slow down the vehicle, not adhesion.

Neither Technician A nor Technician B
