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.
