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
