摘要： A hydraulic brake mechanism (20) is described including a housing (22). A master cylinder assembly (26) is disposed within the housing (22), and the master cylinder assembly (26) includes a fluid chamber (32). The fluid chamber (32) includes a first chamber portion (42) having a first diameter and a second chamber portion (44) having a second diameter, with the first diameter greater than the second diameter. The fluid chamber (32) includes a transition region (46) between the first and second chamber portions (42, 44). The mechanism includes a piston assembly (34) having a piston (74) disposed within the fluid chamber (32). A first seal (36) is configured to sealingly engage between the first chamber portion (42) and the piston (74), and a second seal (38) is configured to sealingly engage between the second chamber portion (44) and the piston (74). The mechanism includes an outlet port (60) extending from the fluid chamber (32) from or adjacent the transition region (46).
