Question

disc brake rotor conditions are being discussed. technician a resurfaces the rotor if it has lateral runout, lacks parallelism, or is scored. technician b resurfaces both the left and right rotors even if only one rotor has problems. who is correct? select one: a. a only b. b only c. both a and b d. neither a nor b

Explanation:

• Technician A: Resurfacing a rotor with lateral runout, lack of parallelism, or scoring is a standard practice as these issues can affect braking performance.
• Technician B: When resurfacing rotors, it is a good practice to resurface both left and right rotors even if only one has problems. This ensures balanced braking performance. If only one is resurfaced, the thickness difference between the two rotors can cause uneven braking.

Answer:

c. both A and B
