Brake test

Imagine you're riding a bicycle and you want to stop. What do you do? You use the brakes! Brakes are what help you stop your bike or a car. In the same way, we need to test the brakes of cars, trucks, and trains to make sure they work properly and keep everyone safe.

A brake test is when experts check the brakes of big vehicles like trucks or trains to make sure they'll stop when they need to. They look at the brake pads, which are kind of like the shoes of the car or train. If the brake pads are worn out, they might not work as well and the vehicle could have trouble stopping.

The experts also look at the braking systems and connections to make sure everything is working together properly. They might test the brakes by pushing a pedal and seeing how quickly the vehicle stops. This way they can make sure the brakes are strong enough to stop the vehicle effectively.

Another important part of brake tests is checking the brake fluid. This is like the blood that makes the brakes work. If there's not enough brake fluid, the brakes might not work as well. So, the experts check the fluid level and look for any leaks that could cause problems.

Overall, a brake test is just a way to check and make sure the brakes of big vehicles are working properly. It's like going to the doctor for a check-up!
