Been fiddling with the linkages again, and think I have it narrowed down to the rear brakes.. Seems no matter what I adjust, whether on the truck or the radio, the rear brakes still drag.. Been looking around looking for close up pics of the center diff with linkages, and saw one pic where the guy had bent the little looped pin that the linkage goes into on top of the center diff... Might try this next...

There is no drag when I hold the gas.. When I brake the braking is too hard and abrupt..

Front braking isn't yet perfect either, but there's no drag with moderate but not strong braking..

If somebody could post a close up pic of their linkage looking right down over the center diff and throttle servo, that would be cool...

Thanks..
