Abstract
A vehicle braking system includes a master cylinder having first and second outputs. First and second hydraulic braking circuits are provided between the respective master cylinder outputs and respective hydraulic wheel cylinders. A first pump provided in the first hydraulic braking circuit is operable to generate pressure and move hydraulic fluid within the first hydraulic braking circuit. A second pump provided in the second hydraulic braking circuit is operable to generate pressure and move hydraulic fluid within the second hydraulic braking circuit. A valving arrangement establishes fluid communication between the first pump and the second hydraulic braking circuit in a first configuration and prevents fluid communication between the first pump and the second hydraulic braking circuit in a second configuration.
