What is checked to assess the brake system's performance during an inspection?

To assess the brake system's performance during an inspection, one of the key aspects evaluated is the condition of the brake pads and the quality of the brake fluid. The thickness of the brake pads is crucial because thinner pads can indicate excessive wear and reduced braking efficiency, which could lead to dangerous driving conditions. Additionally, checking the fluid quality is important, as contaminated or old brake fluid can compromise the brake system's effectiveness, leading to issues like reduced braking power or failure.

While fluid color can give some indication of contamination, a more thorough analysis of the fluid's quality involves checking for moisture content and other contaminants. Brake pedal height is important for overall brake functionality, but it does not directly assess the wear and tear on the braking components. Wheel alignment and tire pressure focus more on vehicle handling and safety rather than brake performance. Similarly, engine oil level relates to engine health and performance, not the brake system. Therefore, checking brake pad thickness and fluid quality provides direct insights into the braking system's effectiveness and safety.
