How do anti-skid systems enhance braking performance?

• A. Increase braking power to lock wheels
• B. Remove brake pressure dynamically
• C. Modulate brake pressure at each wheel to prevent wheel lock and maintain steerability
• D. Disable braking when on wet surfaces

Answer: (C)

Anti-skid systems work by preventing wheel lock during braking and keeping the wheels steerable. They continuously monitor the rotation speed of each wheel. If a wheel starts to slow down too quickly and threaten to lock, the system rapidly reduces the brake pressure on that wheel just enough to let it keep turning. It then applications pressure again in small pulses, repeating this cycle until the wheel traction and steering are optimized. By coordinating pressure at every wheel, the system maximizes braking effectiveness while preserving steering control, especially on slippery surfaces. This approach is why the best choice describes modulating brake pressure at each wheel to prevent wheel lock and maintain steerability. It isn’t about simply increasing braking power to force a lock, nor about removing pressure across the board, and it certainly doesn’t disable braking on wet surfaces—the system actually helps brake more effectively in those conditions by preventing lock.
