Abstract
In a master cylinder (20), a cap (30) for guiding a primary piston (50) is located within an end opening (24) of a body (22) of the master cylinder (20). The end cap (30) retains a sleeve (40) and other components within a bore (12) of the master cylinder (20), and is attached to the body (22) of the master cylinder (20) by way of a biasing retention mechanism (45; 145, 150; 260). The mechanism (45; 145, 150; 260) may bias the end cap (30) axially inwardly of the bore (12), bias a gripping ring member (145) radially outwardly into engagement with the body (22) of the master cylinder (20), and retain a first end (32) of the end cap (30) within the bore (12) in accordance with the extent to which the first end (32) is inserted axially into the bore (12).
