The invention relates to a brake pedal for an engineering machine. The brake pedal comprises a pedal body (2). The pedal body (2) is hinged to a transmission rod (4). The transmission rod (4) is hinged to a rotating plate (7). The pedal body (2) is provided with a pedal switch (5). The pedal switch (5) is connected with a solenoid valve on a power system oil way through a circuit. The invention further discloses an operation method of the brake pedal. By the adoption of the technical scheme, power cutoff is added before the brake process, energy supplied to an engine is reduced by cutting off the oil way, the traction of a whole vehicle is lowered, and then braking is conducted through an air brake valve, so that the air brake valve is operated with a low load, and brake reliability and safety are improved.
