ABSTRACT:
A sealing boot of elastic material for use in a cylinder and piston assembly of an automotive vehicle brake system is disclosed. The boot seats upon the piston and has a radially extending bellows terminating at an annular ring adopted for retention in an annular groove circumscribing the cylinder opening. The boot annular ring is preferably enclosed or otherwise coated with elastomeric material to prevent corrosion thereof and resist disengagement from the receiving groove once seated therein.
