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 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.
