A method and device for brake application provides braking pressure augmentation when preferred. A power booster and master cylinder generate a braking pressure in relation to an operator's input on the brake pedal. An optional brake parameter sensor is used to determine when the power booster reaches a run-out condition. At least one control valve and pump are used to apply braking pressure in response to additional increases in brake pedal application by the operator, after the power booster reaches a run-out condition. The pump and control valve are optionally used to generate braking pressure independent of brake pedal inputs.
