Answer:During the Motor Vehicle Inspection System (MVIS), there are specific tools used to check if a vehicle's braking system is working properly. One of the main devices is a brake tester, which measures how effective the brakes are when applied. It checks things like braking force and balance between the wheels.Another tool often used is a play detector, which helps spot any looseness or issues in the brake components. For heavy-duty vehicles, they might even use a road simulator to mimic real driving conditions and see how the brakes perform under pressure.
