hello all. i have a Caterpillar 320L Serial Number 9kk05261. everything on machine works as it should. machine swings left and right no problem but there is no swing brake. when you let go of the joy sticks with the boom and bucket up it will turn left or right on its own depending on how the machine is sitting. what should i be chasing? is there a swing brake solenoid on the swing motor, should i be looking into the control valve? any help or experience with this issue would be great thanks!!!!
