Abstract
A master cylinder assembly of the type comprises a housing () disposed along an axis (A) defining a chamber () having a cylindrical shape extending horizontally between an open end and a closed end. A first cylinder () and a second cylinder () are disposed for sliding movement axially along the axis. Each of the cylinders includes a cylindrical wall () defining a cylindrical bore (). A piston () is disposed in each of the cylindrical bores. The cylindrical wall of each cylinder includes a cylinder ramp () to define a cylinder ramp shoulder (). Each piston includes a piston ramp () to define a piston ramp shoulder (). The piston ramp shoulder () of each piston and the cylinder ramp shoulder () of each cylinder radially engage one another in an assembled position to allow the cylinders () and the pistons () to abut one another during the sliding movement axially along the axis within the chamber of the housing.
