ABSTRACT:
A tandem master cylinder includes a pair of separately molded plastic cylinder half portions joined together. Each contains a pressure chamber and a piston of the tandem circuit. Coaxial cylindrical bodies surround the cylinder portions, each joining to its respective cylinder portion at a location axially beyond the limits of inward axial travel along the cylinder of seals carried by the pistons so as to account for any differential shrinkage in molding. The cylindrical bodies interconnect at their ends to form a sealed joint locating the cylinder halves in correct radial and axial alignment. Reinforcement members around the cylinder halves resist expansion from internal pressure.
