As long as we are talking about brakes here is my story. Our TT is only about 3 months old. I have a Tekonsha P3 controller. When we first got the TT the brakes were pretty insensitive. The brakes got more sensitive as miles piled up and I would have to keep reducing the voltage on the controller. I'm now down to about 3.5. If I move it up above 4 the brakes really get grabby as I come to a stop. At 3.5 it is not too bad. TT now has about 1000 miles on it and I think the next thing I'll do is pull the drums and have a look see. I appreciate any comments that you have.
