ABSTRACT:
A replaceable cartridge assembly for master cylinder having a housing with a longitudinal bore and an oil inlet connected to the longitudinal bore. The assembly includes a cylinder removably mounted in the longitudinal bore, a pair of seal rings mounted on the cylinder and located on each side of the oil inlet, an axial bore in the cylinder having a fluid outlet at one end connected to the brake system, and a pair of ports connecting the space between the seal rings to the axial bore in the cylinder. A piston in the cylinder has a cup seal around the outside and an O-ring seal spaced from the cup seal. A collar in the end of the axial bore in the cylinder retains the piston in the bore while a spring in the axial bore in the cylinder biases the piston away from the end of the cylinder.
