During what time should you perform brake checks and what tests should you perform?

• A. Only during post-trip
• B. Daily
• C. Only if brakes feel soft
• D. During pre-trip inspection and as needed; test service brakes and parking brake

Answer: (D)

Brake safety hinges on verifying both the service brakes and the parking brake before you drive and whenever needed. Doing brake checks during the pre-trip inspection ensures the vehicle is safe to operate from the start, and testing again as needed helps catch issues that come up on the road.

For the checks, test the service brakes by pressing the pedal to feel for a firm, responsive resistance and to confirm the vehicle slows smoothly without pulling to one side or making unusual noises. Then test the parking brake by applying it firmly to see that it holds the vehicle in place, and then releasing it to ensure it disengages properly. If you notice a soft pedal, longer stopping distances, pulling, or warning lights, perform brake checks again as needed.

This approach is better than waiting until after the trip or only checking brakes when you happen to feel something wrong. It ensures both braking systems are functioning reliably before and during operation.
