Brake Pedal Force Calculator

Formula

The formula to calculate the Brake Pedal Force (BPF) is:

\[ BPF = \frac{BDF}{BPR} \]

Where:

BPF – The brake pedal force in pounds-force (lb-f).
BDF – The brake disc force on the wheel in pounds-force (lb-f).
BPR – The brake pedal ratio.

Definition

Brake Pedal Force (BPF): The amount of force required for a driver to press the brake pedal to stop their vehicle.
Brake Disc Force (BDF): The force exerted by the brake disc on the wheel, measured in pounds-force (lb-f).
Brake Pedal Ratio (BPR): The ratio of the brake pedal's leverage.

Example

Let's say the brake disc force (BDF) is 500 lb-f and the brake pedal ratio (BPR) is 5. Using the formula:

\[ BPF = \frac{500}{5} = 100 \text{ lb-f} \]

So, the brake pedal force is 100 lb-f.

What is a Brake Pedal Force?

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.
