Abstract
The adaptive braking system (10, 110, 210, 310, 410) provides for the combination of a replenishment type anti-skid system having a full power hydraulic brake booster (12) with a pump (80) providing pressure via an accumulator (20) to the booster (12) and a pump-back system wherein the pump (80) communicates make-up pressure to the respective electrically actuated valve mechanisms (70, 170) and brakes when control of the brakes is effected by an electronic control mechanism (90) in response to an incipient skidding condition.
