When we are driving a car or any other vehicle, we use brakes to slow down or stop the vehicle. It is very important to make sure that the brakes are working properly because if they don't work, there can be accidents or other problems.
To check whether the vehicle's brakes are working properly or not, we use something called a brake tester. This is a special machine that measures the amount of force that the vehicle's brakes can produce.
The brake tester has two plates, one on the ground and one on top. The vehicle is driven onto the brake tester, and the top plate applies pressure to the vehicle's wheels. The machine then measures how much force is needed to slow down or stop the vehicle.
If the brake tester shows that the brakes are not working properly, then the vehicle needs to be taken to a mechanic to fix the brakes. This is very important to make sure that the vehicle is safe to drive.
So, a brake tester is a special machine that tests whether the brakes on a vehicle are working properly or not. It helps to keep us safe on the road!
