Structure for caging a return spring of a master cylinder to define limits for an operational chamber. The structure includes a first cylindrical member which engages a first piston and a second cylindrical member which engages a second piston with the return spring being located between the first and second cylindrical members. A stud which has an irregular shaped end member is retained in a groove in the second piston by the second cylindrical member and mated with a head member to define the limits for the return spring between the first and second cylindrical members and correspondingly the maximum size of the chamber within a bore of a master cylinder. |
