How do I use mech. brake w/ tekno conversion?

[raptor50]

yep i tried that still nothing works.. its worse than b/4.. I put the bec in channel 3 and esc in 2 w/o taking out the red wire. when I did that, all worked except that i didnt know where to put the brake servo.. now, when i put the esc w/ red wire taken out and the bec in batt. channel, and the brake servo on 3, the bec, lights up with green light, but steering and throttle doesnt respond.. on the diagram that came w/ the bec states nothing about taking out the red wire, and states putting it in channel 3..

really confused..
