Bill:
Not certain what kit you are talking about, however, if it is the floater kit from the fellow in New Zealand there is additional information available. I have installed several of these kits and they work well if you get them installed correctly. There are a number of tricks.
Go to my club's web site
www.ocmafc.com and click on tech articles in the menu on the left. It will bring up a new menu. There are two reprints of the articles printed in Model A Times (with John LaVoy's permission). Also at the top is my name. Click on my name and it will bring up another menu of articles. There is one there that I wrote about installing the floaters. You will need a tool to center the rear brakes. Bratton sells one for about $40 that works well. The fronts are easier than the backs to do. My advice is do the fronts first and test drive it before you tackle the rears.
Make sure you buy quality brake springs. The ones from Bratton are good. There are some really poor quality ones on the market from some of the other suppliers.
