During a brake inspection, how should the brake pedal be tested?

The brake pedal should be tested with moderate force to effectively assess its responsiveness and functionality. Applying moderate force allows the inspector to gauge how the brake system reacts under conditions that mimic typical driving situations. A properly functioning brake system will exhibit a firm and consistent feel when the pedal is pressed moderately, indicating that the brakes are working effectively and the hydraulic system is responsive.

Testing with minimal force may not reveal issues like brake fade or a spongy pedal feel, since it doesn't simulate the conditions under which brakes are most commonly engaged. Conversely, using maximum force can introduce excessive strain on the system, potentially masking problems that would otherwise be noticeable at lower pressures. Lastly, not pressing the pedal at all would obviously prevent any assessment of the brake system's condition, leaving critical issues undetected. Therefore, moderate force strikes the right balance for an accurate evaluation of the brake system's performance.
