A brake pedal assembly of a vehicle is provided to prevent an operation lever from being drawn to a driver by a push rod when in a head-on collision by allowing double tubes of the push rod to be slid each other. In a brake pedal assembly of a vehicle, a push rod unit comprises a first push rod(21), a second push rod(23), a link bar(25), and a cam block(27). The first push rod has a pin groove(31) at two sides of an end, and of which one end is linked to a booster. The second push rod is connected to one part of an operation rod through a hinge bracket(33). An end of the first push rod is fitted to a hollow inner part of the second push rod. A center of the link bar is hinged to two sides of a front end of the second push rod through the hinge bracket. A spring(35) is interposed between a rear part of the link bar and the second push rod. The link bar has an assembling pin(37) at a front end. The assembling pin is assembled to the pin groove of the push rod by force of the spring. The cam block is placed at two side surfaces of a through hole(41) of a dash panel(5) and mated to a rear end of the link bars, and spreads a front end of link bars through an inclination surface(39). |
