Abstract
A sub master cylinder includes a body formed with a chamber in which oil is stored; a first sub piston having one end which is secured to one end of the body and the other end which extends toward the other end of the body and is disposed to cross the chamber; and a second sub piston disposed between an inner surface of the body and an outer surface of the first sub piston to be moved in the chamber.
Claims19
A sub master cylinder comprising:
- a body formed with a chamber in which oil is stored;
- a first sub piston having one end which is secured to one end of the body and the other end which extends toward the other end of the body and is disposed to cross the chamber;
- and
- a second sub piston disposed between an inner surface of the body and an outer surface of the first sub piston to be moved in the chamber.

A brake apparatus comprising:
- a sub master cylinder including a body formed with a chamber in which oil is stored, a first sub piston having one end which is secured to one end of the body and the other end which extends toward the other end of the body and is disposed to cross the chamber, and a second sub piston disposed between an inner surface of the body and an outer surface of the first sub piston to be moved in the chamber;
- a master cylinder in which a first piston and a second piston are connected in series, wherein, in order to brake wheels, a hydraulic pressure is generated as the first piston is moved, and a hydraulic pressure is generated as the second piston is moved by movement of the first piston or a hydraulic pressure is generated as the second piston is moved by a hydraulic pressure transmitted through a first hydraulic line;
- and
- a hydraulic pressure diversion member configured to divert flow of a hydraulic pressure from the sub master cylinder to a pedal simulator or to the hydraulic line which is connected to the master cylinder.
