摘要

A method for manufacturing a master cylinder for a brake system, comprising a cylindrical main body, at least one flange integrally connected therewith, and a bore, extending in the cylindrical main body and through said at least one flange, wherein the master cylinder is manufactured by cold forging. <??>Preferably the flange is cold forged by upsetting. Subsequently the cylindrical main body is provided with a bore. Said bore is realized in a series of forging steps, wherein at least the portion where the bore pierces the flange is executed in a separate step. <IMAGE>
