How can I get the Auto Brake on my 777 to work with my Gulfstream IV. I saw that in the air cfg. that the brakes are the same so I put in the Auto Brake switch in the panel to try it out. The switch works back and forth but it won't slow down the plane at all. Am I doing something wrong there or maybe it's something I can't do! What say YE. Thanks in advance, Wildie.
