How come the brakes didn’t apply on the unit or is there a different set up in the States ?The yellow button is just for tractor parking brake, pushed in while driving, pull out to apply tractor parking brakes only not trailer as well.
Red one just for trailer is also pushed in while driving but when our super trucker pulled the tandems out it would have snapped the airlines and with air just rushing out the red button would have popped out to stop air going to the trailer and emptying the air tanks.
I am much obliged m’lud !
