A vehicle braking system includes a master cylinder, and a wheel cylinder. A primary braking unit includes a first pressure generating unit distinct from the master cylinder and is operable to actuate a braking action at the wheel cylinder in a primary mode of operation. The primary braking unit further includes an outlet port connecting the primary braking unit to the wheel cylinder. A secondary braking unit includes a second pressure generating unit distinct from the master cylinder and operable to actuate a braking action at the wheel cylinder in a secondary mode of operation. The secondary braking unit an inlet port connected to the outlet port of the primary braking unit. The primary braking unit includes one or more ABS valves operable to control traction control and anti-lock braking in the primary mode of operation and located between the first pressure generating unit and the outlet port of the primary braking unit. The secondary braking unit is located between the one or more ABS valves and the wheel cylinder.
