What does brake pedal travel checking entail?

Brake pedal travel checking entails measuring the distance the brake pedal descends before the driver feels any resistance when applying the brakes. This is a critical part of ensuring the brake system is functioning properly, as excessive travel before resistance can indicate issues such as air in the brake lines, worn brake pads, or problems with the brake fluid.

This process is essential in maintaining vehicle safety, as it directly relates to how responsive the brakes are when engaged. Proper brake pedal travel is crucial for effective braking and can help prevent accidents caused by insufficient braking power.

In contrast, measuring the distance the pedal moves while driving or how much it travels during emergency braking doesn't accurately assess the safety and responsiveness of the braking system in normal operating conditions. The movement of the brake pedal during acceleration is also unrelated to its braking function.
