Abstract: A boost arrangement for pressurizing a master cylinder of a vehicle braking system of a vehicle includes a housing, a primary piston and a secondary piston. The housing defines a boost chamber filled with brake fluid. The primary piston is disposed in the boost chamber and defines an opening extending therethrough. The secondary piston has an end extending into the opening defined by the primary piston.

Abstract: A braking system for a vehicle is operative to apply a friction brake force to at least one wheel of the vehicle. The braking system includes a master cylinder is in fluid communication with a reservoir of brake fluid and in fluid communication with the hydraulic brake device. According to one aspect, the braking system includes an electric brake force generator which moves the brake fluid within the master cylinder to deliver brake fluid to the friction brake device in response to a first predetermined displacement of a brake pedal. The electric brake force generator includes a housing defining a boost chamber filled with brake fluid and in fluid communication with the reservoir of brake fluid and further includes a drive arrangement for creating pressure in the boost chamber. In accordance with another aspect, the braking system includes a mechanical brake force generator is disposed between a brake pedal and a primary piston of the master cylinder which is operative to actuate the master cylinder in response to a predetermined displacement of the brake pedal.
