A bicycle brake lever has a body (10), a hydraulic cylinder (12), an oil jacket (14), a cap (15) and a leakage proof element (16). The body (10) has a threaded hole and a lever (11). The hydraulic cylinder (12) is mounted on the body (10) and has an oil chamber (122), a piston (13) and an annular groove (124). The piston (13) is mounted moveably in the oil chamber (122) and is connected with the lever (11). The annular groove (124) is formed around the hydraulic cylinder (12). The oil jacket (14) is mounted rotatably around the hydraulic cylinder (12) over the annular groove (124) and has a tube (142). The cap (15) is mounted over the opening of the tube (142). The leakage proof element (16) is mounted between the opening of the tube (142) and the cap (15). The oil jacket (14) and tube (142) may be made of translucent material, to allow inspection of the hydraulic fluid level. |
