I just got a 3.3 tmaxx on ebay. It runs great, the only thing is after i brake. the bar that the servo pulls to brake stays in the brake possition, and the brake stays on some what. When i move the bar back and forth with my hand it is hard to move. As you can tell i am new to this.The dics brake heats up very hot aslo. anybody understand what im talking about? and have any solutions??????
