Disc Brake Piston Puller

US Patent:
4009515, Mar 1, 1977
Jan 23, 1976
Appl. No.:
Charles Racin - Clinton OH
International Classification:
B23P 1904
US Classification:
A tool, for manually releasing a frozen automotive brake piston from a cylindrical cavity of a disc brake caliper, has an elongated shank on an inner end of which a solid axially tapered segmental head, defining an outer tapered wall, is axially adjustably mounted. A plurality of peripherally spaced piston gripping segments are axially slidably adjustable on the tapered wall of the solid head to be radially adjusted thereon toward and from clamped engagement of the segments with the piston cavity wall. A first stop means is threaded on the outer end portion of the shank, as for axially adjustably supporting the shank to a fixed part of the brake caliper, and a second stop means may be threaded on the shank, axially inwardly of the first stop means, for selective adjustment of the tool head segments directly on said tapered wall for initially gripping or clamping the tool head to the piston wall whereby the shank may be turned to draw the second stop means and the tapered head together, first to increase the clamping grip of the segments against the piston wall, and then draw the piston toward the anchored first stop means and free of the caliper.
