Brake efficiency, expressed as a percentage, calculates how effective your brakes are when you hit them lightly and hard, according to the “MOT Inspection Manual.” Brake efficiency depends on the weight of your vehicle and the strength of your brakes. Learning how to calculate brake efficiency can help you determine if your brakes are working normally or if they need to be changed. Strong brakes in tough elements like snow and rain can help prevent a potentially fatal accident.

#### Step 1

Calculate the total braking effort of your car, which can only be done in a mechanic shop. The total braking effort is equal to the effort it takes to stop your car when you press the floor brake. The test is done on a tire machine that automatically spins your tires and then stops them suddenly. Simulates the real braking of a car. Ask your mechanic to test the car on the tire machine and they can give you a total estimate of the braking effort.

#### Step 2

Calculate the weight of the vehicle. Vehicle weight can be found in the vehicle manual.

Divide the weight of the vehicle by the total braking effort and then multiply the number by 100 to get the percentage of braking efficiency.

#### Tip

• Also weigh everything inside your car, because that will affect the brakes.
