ABSTRACT:
A brake stroke simulator for achieving good stroke feeling in a vehicular brake apparatus has a first piston being displaceable by receiving a master cylinder pressure, and a second piston disposed so as to form a gap between the second piston and the first piston. A plug is disposed so as to form another gap between the plug and the second piston. A first spring is disposed between the first piston and the second piston so as to urge the pistons away from each other. A second spring is provided for urging the second piston away from the plug. The brake stroke simulator is able to reduce the characteristic variations among individual products.
