1. A method of operation for a vehicle braking system including a driver activated brake pedal, a brake pressure modulator, and an anti-lock brake control that activates the brake pressure modulator to modulate vehicle braking upon detection of an insipient wheel lock condition, the method comprising the steps of:

  • periodically measuring vehicle deceleration and a brake pedal position during activation of the braking system when said insipient wheel lock condition is not detected;

    identifying conditions of degraded braking effectiveness based on the periodically measured deceleration and brake pedal position; and

    adaptively adjusting a brake pressure control parameter of said anti-lock brake control when a condition of degraded braking effectiveness is identified so as to compensate for the identified condition.
