ABSTRACT:
A master cylinder apparatus is provided with a master cylinder and a booster. The booster comprises a booster shell whose interior is divided into a variable and constant pressure chambers. The master cylinder comprises a master piston inserted in a cylinder body. The cylinder body includes an installation flange to which the booster shell is attached. When the brake pedal is operated, a pull mechanism operates a control valve to communicate the variable-pressure chamber with atmosphere. The master piston is moved by an output member of the booster to generate a fluid pressure in the master cylinder that is delivered to wheel cylinders. The installation flange of the cylinder body can be attached to a dashboard so that the booster shell is disposed in the passenger room or the engine room, with the cylinder body protruding into the other room.
