Can I manually adjust my neverlube self adjusting brakes

[stanleyz]

So in a day or two I'm gonna take off a hub and check how the brake pads look. I suspect a problem but I'm not sure. My brakes seem weak but I can't check voltage with the Ford wiring system because the brake controller won't send a signal until 5 or 8 or something miles per hour. When I hook up and do a pre trip check by squeezing the controller I get just a bit of drag but I don't think I've ever had more with this truck. The other clue is that front pads on the truck were very worn at 35,000 miles. So if the pads look OK can I manually adjust them without fouling up the automatic adjusters? Thanks for your response.
