Motion limiting device for inertial spool brakes for fishing reels

A centrifugally actuated braking system on an end flange of the line spool of a bait cast reel. A series of raised lands or stops on the end flange cooperates with projections on the brake pads mounted on radiating brake arms to limit radial movement of the centrifugally actuated brake pads. Orthogonal brake arms are joined by an arcuate section which rides in an annular groove in the spool shaft. Additional weights for increasing braking power may be slidingly mounted on the brake arms behind the brake pads. A retainer ring sliding onto the spool shaft holds the brake arms in place. An inner lip on the retainer ring rides in a second annular groove in the spool shaft to hold the retainer ring in its locking position on the shaft.
