The invention relates to a brake pedal (1) intended to equip a vehicle, particularly a motor vehicle, comprising a framework structure (2) mounted to rotate about a first rotation spindle (3) designed to be connected to the bulkhead of the vehicle, a pedal web (4) to one end (4a) of which is fixed a peg (5) designed to slide in a slot (21) made in the framework structure (2), a movement mechanism (7) to cause the peg to slide in the slot, defining a length (L) between the rotation spindle of the framework structure and the other end (4b) of the pedal web, a first link (8) connected to the framework structure and mounted to rotate about a second rotation spindle (9) designed to be connected to the bulkhead of the vehicle, a connection (13) designed to receive the end of the rod of the brake booster at a distance (R) from the second rotation spindle. According to the invention, this pedal comprises means (13, 14, 16, 17) for obtaining a constant step-down ratio (L/R).
