During a pre-trip inspection, why should you also check the amount of free play in the brake pedal before it engages?

Pick an answer

1. Pedal free play only matters for driver comfort, not brake adjustment
2. Excess play can be a sign of a problem in the linkage or valves, similar to how excess pushrod travel signals a brake out of adjustment
3. Free play in the pedal is only a comfort feature with no safety relevance, since the linkage itself cannot wear out or loosen over time
4. Checking pedal play is only necessary on vehicles without air brakes
