<p>A brake lever arm (30) is mounted to a base member (10), with the base member fixed to a bicycle handlebar (15). The lever arm (30) is pivotal about a pivot point (25) on the base (10). The lever arm (30) includes an adjusting mechanism (40) that adjusts the position of the lever arm (30) when the lever arm (30) is in a brake dis-engaged position. The adjusting mechanism (40) may be slideable in grooves (35, 36, 38) in the lever arm (30) such that the adjusting mechanism (40) may be moved to positions that are differing distances away from the pivot point (25). Alternatively, the adjusting mechanism may be moved to positions which are differing distances away from the pivot point in other ways, for example by attachment to the lever arm by a screw which passes through a selected one of a number of apertures in the lever arm. The adjusting mechanism includes a contact member (60) that engages a brake cable (C) connected to the lever arm (30) when the lever arm (30) is moved from the brake dis-engaged position toward a brake engagement position. The position of the contact member (60) with respect to the pivot point (25) determines the effect movement of the lever arm (30) has on the cable (C). In this manner, the adjusting mechanism (40) adjusts the length of the stroke or travel of the lever arm (30) from the brake dis-engaged position to the brake engagement position. <IMAGE> <IMAGE></p> |
