Brake stroke simulator and a vehicle hydraulic brake apparatus provided with the same

摘要

A brake stroke simulator includes a first movable member freely slidably disposed in a housing and defining a hydraulic pressure chamber at one end of the first movable member that is adapted to be supplied with hydraulic pressure corresponding to braking operation of a brake pedal, and a second movable member disposed at the other end of the first movable member in the housing movable integrally with the first movable member. A first spring biases the first movable member and a second spring biases the second movable member. A shock absorbing elastic member is compressed by the sliding movement of the first movable member against the biasing force of the first spring and is compressed by the sliding movement of the second movable member against the biasing force of the second piston.
