Abstract
A brake lever for an automotive S-cam drum brake has a toothed conical clutch (14) for transmitting torque in one direction between two coaxial members (4, 10) rotatably arranged relative to each other. Each tooth in this clutch is asymmetrical, its torque transmitting flank forming a greater angle with the normal than its opposite flank.

A brake lever for an automotive S-cam drum brake, having a toothed one-way clutch (14) for transmitting torque through a torque transmitting tooth flank in a slack decreasing direction between two coaxial members (4, 10) rotatably arranged relative to each other, characterized in that each clutch tooth is asymmetrical, its torque transmitting flank forming a greater angle with a normal, which extends through the tooth apex and into the tooth, than an opposite tooth flank thereby to provide a greater flank length with longer life.
