A master cylinder (12) and proportioning valve assembly (52), comprise a housing (18) with a pair of pistons (22, 24) movable therein to generate fluid pressure during braking. The proportioning valve assembly (52), forms a mechanical connection (82), with one of the pistons (24) to render the proportioning valve inoperative in response to the position of the one piston in the housing. |
