During a brake inspection, what is the most crucial item to check?

When conducting a brake inspection, the wear on brake linings is the most crucial item to check. Brake linings are the components that create friction against the brake drum or rotor, which is essential for slowing down or stopping the vehicle. If the linings are worn down excessively, they may not provide adequate stopping power, which can lead to increased stopping distances or even brake failure.

Monitoring brake lining wear ensures that the braking system is functioning effectively and safely. Regular inspection can help identify when the linings need replacement, maintaining overall vehicle safety. Other factors, such as brake fluid color or pedal feel, while important, do not directly indicate the efficiency of the brake system in the same critical manner as the condition of the brake linings does. Any noise from the brakes can also indicate a problem but should primarily signal an inspection of the linings for wear or damage.
