Abstract
An adaptive braking system (10, 210) for an automotive vehicle provides a three-channel split pump-back system which may be utilized with either two- or three-chamber master cylinders. The three-channel adaptive braking system (10, 210) includes a first braking circuit (40) for controlling one of the front wheel brakes (25), a second braking circuit (60) for controlling the other of the front wheel brakes (27), and a third braking circuit (80) for controlling the rear wheel brakes (24). A two-section pump (110) provides hydraulic pressure for the first and second braking circuits (40, 60) and for the third braking circuit (80). Alternatively, a three-section pump (310) can provide hydraulic pressure for each of the circuits (40, 60, 80).
