1. A method for efficiently decelerating a vehicle having a braking circuit for actuating a set of brake actuators, the method comprising the steps of:
- generating a flow of pressurized brake fluid within said braking circuit;
determining normal force parameters exerted on each wheel of said braking circuit; and
isolating at least one respective brake actuator of said braking circuit from receiving pressurized brake fluid during an initial stage of braking, said isolation increasing said flow of pressurized brake fluid to a non-isolated brake actuator of said brake circuit in response to said normal force parameters.

Abstract
A method is provided for efficiently decelerating a vehicle having a braking circuit for braking a set of brake actuators. A flow of pressurized brake fluid is generated within the braking circuit. Normal force parameters exerted on each wheel of the braking circuit are determined. At least one respective brake actuator is isolated from receiving pressurized brake fluid for increasing the flow of pressurized brake fluid to a non-isolated wheel of the brake circuit in response to the normal force parameters.
