I haven't tried to start it with the the brake on, I just know that when it is running and I apply the brake it sounds pretty bad. Afraid that I will damage something if I use the brake. It going to be really hard not to use it, like letting the engine warm up this winter for plowing snow.even the smallest creep with brake on it will be noisy as motor is prevented from moving, if the noise starts does releasing brake stop the noise?
