What should an inspection mechanic check first when assessing a vehicle's brakes?

• A. The brake pedal's firmness and travel
• B. Brake fluid level
• C. The sound of the brakes
• D. The color of the brake pads

Answer: (A)

When assessing a vehicle's brakes, the inspection mechanic should prioritize checking the brake pedal's firmness and travel first. This step is critical because the brake pedal is the primary interface between the driver and the braking system. A firm pedal indicates that the hydraulic system is functioning correctly and that there are no air leaks or fluid loss, which could compromise braking performance. Additionally, the travel of the pedal can reveal issues such as worn components or misadjustment in the braking system. Proper pedal travel ensures that the brakes engage and disengage effectively, providing the driver with the necessary control when stopping. Although checking the brake fluid level, sound of the brakes, and color of the brake pads are all important aspects of a comprehensive brake inspection, they are secondary to understanding the immediate feedback from the brake pedal. Assessing the pedal's condition gives a solid initial indicator of the overall health of the braking system.
