RE: I'm just about done
I think 90% of people that run nitro rc's are using fuel tubing on there brake linkage, its what I have always used. And I have heard that it will give the brakes better response from one magazine or another. I know on the monster GT its the only way to get some kind of braking power, I got my brother one and he kept complaining about the brakes not working, adjusted it all the way and still didnt work right. A peice of fuel tubing curred it.
So just try it, it isnt that big of a modification that its going to ruin something or cannot be reversed. It can only make you know more about your brakes/truck and how they/it works.
