Brake shoe with spring brake member

A brake assembly for locking a slidable sash window within a track of a frame, the track having a pair of spaced apart, opposed sidewalls, the assembly comprising:

• a slider body adapted for slidable motion within the track, the slider body having a central opening extending from a front face to a rear face and having a side opening adjacent to the central opening;
• a brake member comprising a spring having an end portion having a first segment and a second segment, the first segment curving inwardly and the second segment curving outwardly and having a braking surface thereon, the brake member mounted within the slider body such that the end portion is adapted for reciprocal lateral movement through the side opening;
• a cam positioned in the central opening;
• wherein the slider body is adapted to receive the brake member and the cam is adapted to be rotatable in the central opening for laterally biasing the end portion for movement through the side opening wherein the braking surface is adapted to frictionally engage one of the opposed side walls.
