## What is Brake Force Bias & Torque?

Locking rear brakes before fronts means spin-outs. Too much front bias means wasted stopping distance. This calculator shows your actual brake bias versus the ideal bias for your setup.

Enter vehicle weight, weight distribution, wheelbase, CG height, and target deceleration to calculate dynamic weight transfer and ideal front/rear brake bias. Then enter front and rear rotor diameters, piston diameters, master cylinder bore, pedal ratio, pedal force, and friction coefficient.

WHAT IT CALCULATES:
- Dynamic weight transfer under braking
- Ideal front/rear brake force split
- Line pressure from pedal input
- Front and rear clamp force
- Braking torque per axle
- Actual vs ideal bias comparison

KEY FEATURES:
- Bias safety window indicator
- Weight transfer physics
- Works completely offline

Built for race car builders, brake system tuners, autocross and drift enthusiasts, and automotive engineers.
