Parking brake operation should be tested by verifying what?

• A. Application and holding devices for functionality
• B. Tire pressure
• C. ABS status light
• D. Engine oil level

Answer: (A)

Parking brake operation is tested by confirming that the system that actually applies and holds the brakes functions properly. When you engage the parking brake, the mechanism—whether a cable-driven shoe/pawl system or an electronic actuator—should engage fully and reliably hold the vehicle in place, especially on an incline. The test also checks that the brake releases cleanly and that there isn’t excessive travel or drag after release. Tire pressure, ABS warning lights, or engine oil level don’t determine whether the parking brake will hold the vehicle, so they aren’t part of this test.
