[Answer] Which of the following would MOST LIKELY happen if the measurements taken from the check shown above varied from the manufacture’s specifications?A. noisy brake operationB. brake grab or pullC. pulsating brake pedalD. low brake pedal

Answer: C. Poor rotor parallelism (thickness variation) will cause a pulsating brake pedal. This is due to the caliper piston movement that occurs as the pad rides over the alternating high and low areas on the disc. This action forces brake fluid to flow back and forth from the caliper to the master cylinder creating the pulsating pedal feedback.
