ABSTRACT:
A compliance spring is disposed between the brake pedal and the primary piston of a master cylinder, preferably between the push rod and the primary piston of the master cylinder. Selection of the initial spring compression load of the compliance spring, its permitted spring compression travel and its spring constant, allow for both a simplified and fine adjustment of the brake pedal feel per a brake feel index.
