ABSTRACT:
A compression rod assembly with its button end in tight engagement with a valve body of an automotive power brake unit in a socket of said body having a flow hole at the inner end of the socket has a plunger at the opposite end of said assembly in tight engagement with the piston of a master brake fluid cylinder. The button end of said assembly comprises a hollow button with an internal hollow boss and an annular space therearound. A resilient disc with its diameter complementary to the internal diameter of the button and tightly fitted therein projects from the button to engage the valve body around the flow hole, and a noncompressible disc is similarly fitted into the button, bearing against the boss and the inner side of the resilient disc. A rod is press-fitted at one end into the hollow boss bearing against the inner end thereof and the opposite end of the rod has a plunger threaded therein, the plunger having a head in said engagement with the master brake cylinder piston.
