SECONDARY PISTON STOP-WIRE RETAINER RING

摘要

A novel stop for the secondary piston of a split master cylinder is disclosed. The stop includes a radially expandable, circumferentially extending portion received in a circumferentially extending groove provided in the secondary fill port of the master cylinder and another portion extending coaxially with the axis of the port that projects into the master cylinder bore. Movement of the secondary piston past the portion of the piston stop that projects into said bore is thereby prevented.
