Braking performance in a hydraulic system is about how the pedal input translates into brake pressure. Pedal travel is the distance the pedal moves before the brakes engage; a small, consistent travel range indicates proper linkage and system pressure, while excessive travel can indicate air in the lines, worn components, or low fluid. Pedal effort is the amount of force required to depress the pedal; abnormally high effort suggests hydraulic resistance or leaks, while an unusually light pedal may signal a pressure loss or poor system integrity. Pedal feel is the feedback the driver senses through the pedal; a firm, progressive feel typically reflects healthy hydraulics, whereas a spongy or soft pedal indicates air in the lines, leaks, or moisture in the fluid. The other items—ABS light status, headlight alignment, and engine idle speed—do not directly measure braking performance in normal hydraulic operation.
