Zusammenfassung:	An automatic brake adjustment for small transmissions, such as used with riding lawn mowers and the like. A brake disc rotated by the transmission is selectively engaged by friction producing pucks brought into engagement with the brake disc by a rotatable lever having a cam operating a puck. The axial position of the brake lever on its supporting shaft is determined by a threaded nut and automatic rotational nut adjustment is produced by a wheel having evenly spaced shoulders in the form of ratchet teeth defined upon its periphery selectively and sequentially engaged by a detent mounted upon the brake lever. When puck wear of sufficient extent occurs, the detent will sequentially engage the following shoulder of that previously engaged to rotate the brake lever adjustment nut during the next brake actuation thereby translating the brake lever and puck toward the brake disc to compensate for puck wear.
