The invention discloses a brake rod of a drum brake device, the drum brake device and a heavy duty vehicle. A brake lever (20) for a drum brake device (12), designed for transmitting movement of a cylinder rod (14) to a brake shaft (22), where the brake lever (20) comprises a first portion (20a) defining a bore (24) for fitting the brake shaft (22) and a second portion (20b) configured to be pivotally connected to the cylinder rod (14), and where the brake lever (20) is configured to transmit movement of the cylinder rod (14) to the brake shaft (22). The first portion and the second portion are offset from each other with respect to a central axis (X24) of the bore (24). The brake lever further comprises a reinforcing member (28) extending in a direction (L1) contained inside a plane (P1) perpendicular to the central axis (X24) of the bore and comprising an aperture (32) for fitting the brake shaft (22).
