PURPOSE: A master cylinder of a tandem type having a reservoir tank is provided to easily replace polluted brake fluid and to prevent an accident by reducing wear of a front lining. CONSTITUTION: A reservoir tank of A type fixes a pump on an upper of a tank, and a reservoir tank of B type fixes the pump on a side of the tank. The reservoir tank is made by transparent plastic to check a polluted state of brake fluid. An upper portion of the reservoir tank is a flat square shape, and front and rear portions are curved line shape. A middle portion of a front in the tank is protruded as 2cm by forming an inject port and a cap. Two hemispheres having diameter of 3.5cm are installed on both ends of the reservoir tank. Moreover, a semi circle having radius of 6.8mm is mounted between the hemispheres as a straight-line shape to fix a drain pump. Then, four circular protrusions are formed by having height of 3mm.
