Final answer:
To check if your service brakes are working properly, perform a brake test by driving at a specific speed and applying the brakes until the car stops. Record either the time it takes or the distance covered. If the car takes a long time or covers too much distance before stopping, there may be a brake problem.
Step-by-step explanation:
To check if your service brakes are working properly, you can perform a brake test. This can be done by driving the car at a specific speed, such as 50 mph, and then applying the brakes until the car comes to a complete stop. You can record either the time it takes for the car to stop or the distance it covers before stopping.
By performing this test, you can determine if your brakes are functioning correctly. If the car takes an unusually long time to stop or covers too much distance before stopping, it may indicate a problem with the brakes that needs to be addressed.
It is important to note that this test should be done in a safe and controlled environment, such as an empty parking lot or a closed-off road.
