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 brake boost assist system for use with a master cylinder of a motor vehicle braking system, includes an inductive sensing system. The inductive sensing system has sensing devices carried on an input member and an output member, where the input and output members are coupled to respective ones of an input rod and an output rod of the brake boost assist system. Movement of the input and output members relative to one another, and relative to a fixed element of the inductive sensing system positioned within the brake boost assist system, enables an accurate estimation of the distance of a pedal gap which separates faces of the input and output rods. The accurate estimation of the pedal gap distance enables a more accurate determination to be made of the braking force required for any given pedal stroke input by an operator of the vehicle during a braking action.
