Technician A says the adjustable pedal assembly uses one motor to control both the brake pedal and the accelerator pedal positions. Technician B says the brake pedal is often the first sign of a brake system concern. Who is correct? A) Technician A B) Technician B. C) Both Technician A and B. D) Neither Technician A or B.

The correct answer is B) Technician B.<br /><br />Technician B is correct in stating that the brake pedal is often the first sign of a brake system concern. Issues with the brake system can manifest as problems with the brake pedal, such as it feeling soft, spongy, or not returning to its normal position after being depressed.<br /><br />Technician A's statement is incorrect. In most vehicles, the brake pedal and the accelerator pedal are controlled by separate hydraulic systems and motors. The adjustable pedal assembly typically refers to the ability to adjust the position of the pedals, which is usually done manually and does not involve a motor controlling both pedals simultaneously.
