✓ Correct answer: A. 0.001 inches Rotor parallelism reflects the uniformity of thickness across the rotor surfaces. The maximum allowable thickness variation is typically 0.001 inches. Exceeding this limit can result in brake pulsation or uneven braking, thus requiring the rotor to be machined or replaced to ensure safe braking performance.
