ABSTRACT:
The present invention provides a vehicle wheel cylinder for a drum type brake. The sealing boot which seals the wheel cylinder frame and piston is provided in a preferred embodiment with annular rings which help protect the integrity of the sealed relationship of the annular boot with the bore of the wheel cylinder against damage which can be caused by contact of the sealing boot with a web of a brake shoe.
