Abstract
A master cylinder for braking of reduced size and complexity and a method of making a master cylinder. The master cylinder includes a sub-tank for supplying working oil for braking, the sub-tank being integrally connected to a master cylinder main body. A first port and a second port are formed close to one another in a partition wall separating the master cylinder main body from the sub-tank. The sub-tank has a first opening and a second opening. The axes of the first and second ports in the partition wall pass through the first opening in the sub-tank, which allows tools to be inserted through the first opening to form both ports.
