The front-rear distribution of a car’s braking power.
For the shortest stopping distance, brake bias should match the car’s traction at each end during hard braking brake modulation.
Brake bias is the process of varying pedal pressure to hold a car’s brakes on the verge of lockup.
Ideally, the brakes will unlock with only a slight reduction in the pressure needed to lock them. Typically, however, a considerable pressure reduction is required.
