I had re-tracks with the original cable breaks. They worked well enough. I went in and out a 2000 foot strip all the time. Course it was grass so that helps too. But I found out that if you put a fixed gear with disk breaks and wheel pants the airplane is actually faster. Y'all worrying about things you really don't need to worry about. If I were you I would worry about the power plant installed on the front of the airplane. I enjoyed my car for quite a while. Went through about five Volkswagen engines and finally I installed An O-200 and that was the best thing I ever did. I never could get brakes to hold the airplane at full throttle. I have an airplane with an 0-360 and above 2500 RPM it won't hold either. Course it's a 1947 model but it does have Cleveland brakes
