The first thing you should do if you have not already is buy a 6v hump pack for the receiver and rechargeable AA batteries for the radio. This will help a lot. Standard alkalein batteries wear down very quickly. On adjusting the breaks, I adjusted mine with the throttle servo at neutral. I loosened the set screw that holds the brake adjustment and set it so the truck rolled freely but the brakes grab with just a little pressure. It will take a couple times to get it right.
