When assessing brakes during a pre-trip inspection, what should be prioritized?

Prioritizing the assessment of brakes by checking for proper pedal response and pressure is crucial because it directly affects the vehicle's stopping ability and overall safety. The brake pedal should have a firm and responsive feel when pressed; a spongy or loose pedal may indicate air in the brake lines or low brake fluid, which can compromise braking performance. Ensuring that the brakes engage smoothly and effectively is essential for the operator's control of the vehicle during operation.

While observing for signs of tire wear, listening for unusual sounds when braking, and reviewing brake fluid levels are important parts of a thorough pre-trip inspection, they are secondary to the critical function of the brake pedal itself. For instance, tire wear can indeed affect stopping distance, but it does not directly assess the immediate operational status of the braking system at the moment of use. Listening for sounds is also an important indicator of potential issues but requires the brakes to be engaged properly first to notice any abnormalities. Reviewing fluid levels can reveal maintenance needs but does not provide immediate feedback on how the braking system is operating in real-time.
