What is the recommended method for testing brakes?

The recommended method for testing brakes is to drive at a slow speed, typically around 5 mph, and then apply the brakes to ensure that the vehicle comes to a complete stop. This method is effective because it allows the driver to assess the responsiveness and effectiveness of the brakes without putting themselves or others in danger. At this slow speed, any issues with the brakes can be detected early on, providing the driver with enough time to react and address potential problems before they escalate.

Testing brakes at higher speeds, like accelerating to 20 mph, could increase the risk of an accident if the brakes do not perform adequately. Testing the brakes only when stationary does not provide a real-world assessment of their functionality, as brakes are primarily used while the vehicle is in motion. Additionally, using the handbrake while driving is not a typical method for brake testing and can lead to loss of control or potential damage to the vehicle. Therefore, moving at a low speed and applying the brakes is the safest and most effective way to ensure that they are functioning properly.
