Abstract
A hydraulic reservoir and master cylinder assembly having a piston with a blind bore for receiving an input rod, the piston having a breather valve therein provided with opening means operated by an abutment projecting laterally into the master cylinder bore and which is received into a slot in the piston. In order that the abutment be as short as possible and therefore that the slot be as shallow as possible, the piston carries a pivoted lever extending transversely of the piston and which is engageable with the abutment to operate the breather valve.
