ABSTRACT:
A master cylinder includes a cylinder defining a cylinder bore therein with one end of the cylinder being open, a sleeve fitted into the cylinder bore, a piston slidably disposed in the sleeve, and a stopper mounted on the one end of the cylinder for abutting against the sleeve to prevent the sleeve from coming off the cylinder. The sleeve includes at least two sleeve members fitted into the cylinder bore in serial disposition from the inner end to the open end of the cylinder bore. A cup seal is disposed between two adjacent sleeve members of the aforementioned at least two sleeve members. The master cylinder further includes a resilient member for forcing one inner sleeve member of the two adjacent sleeve members onto the other sleeve member of the two adjacent sleeve members, thereby forcing the other sleeve member toward the stopper.
