Enter the force required for the brake disc to close on the wheel and the brake pedal ratio into the calculator to determine the brake pedal force.

## Brake Pedal Force Formula

The following equation is used to calculate the Brake Pedal Force.

BPF = BDF / BPR
• Where BPF is the brake pedal force (lb-f)
• BDF is the brake disc force on the wheel (lb-f)
• BPR is the brake pedal ratio

To calculate the brake pedal force, divide the brake disc force by the brake pedal ratio.

## What is a Brake Pedal Force?

Definition:

The brake pedal force is the amount measured in pounds or kilograms required for a driver to press the brake pedal to stop their vehicle.

For example, if you were driving a car and your brake pedal force was 50 pounds, you would need to apply at least 50 pounds of pressure on your brake pedal to bring your vehicle to a stop.

## How to Calculate Brake Pedal Force?

Example Problem:

The following example outlines the steps and information needed to calculate the Brake Pedal Force.

First, determine the brake disc force. In this example, the brake disc needs to exert a force of 600 lb-f on the wheel to brake properly.

Next, determine the brake pedal ratio. In this case, the brake pedal ratio is measured to be 8:1.

Finally, calculate the brake pedal force using the formula above:

BPF = BDF / BPR

BPF = 600 / 8

BPF = 75 lb-f
