Abstract

A guide ring for a piston pump of a vehicle brake system includes a body and a seal. The body is configured to movably support a piston of the piston pump in a cylinder liner. The seal is held on the guide ring and configured to inhibit passage of air between the piston and the guide ring during movement of the piston.
