Yes, but at the cost of accelerated gearbox wear(This answer is for recreational karts only).

Recreational karts use the same single-speed transmission as motorcycles, so you can think of the connection as being half-clutched all the time. Pressing the gas pedal and brake at the same time will result in accelerated transmission wear and intense heating, and in severe cases the transmission will die from high temperatures, which is why the staff emphasizes that you should not press the accelerator and brake at the same time.

If you want to maintain the speed, you need to release the oil through the larger corners out of the corner in advance to open the oil can be, due to the characteristics of the single-speed transmission, the wheels and the engine is not rigidly connected, do not have to worry about opening the oil in advance to destroy the dynamics of the body; if it is through the smaller corners, you do not want to let go of the oil caused by the drop in speed, you can keep the throttle open at the same time to point the brakes to help the center of the transfer, do not step on too much, it will be fine.
