I found that when I swaped from drums to disc the stock master cyl was fine. Thats for a singe piston rear disc brake. Looking at the surface area of the single piston and the bore and longer stroke of the drum cyls it ended up about a wash on that car. I dont expect to need a larger master cyl, I do expect to maybe need a prop valve maybe a resi act too but Ill add them if needed but these kits and calipers are made for semi float axles so I expect it to go smooth. Summit has a nice prop valve for under $70 if I recall. Im going to TRY to do it for under $500 so stay tuned. I may have already found a set of calipers for free from a budy so thats a big savings right there.
I spoke with sky and they said you can al la cart any of there parts no problem. We are leaving for some hard earned vacation tonight and the little lady is into me on that as is so Im not sure when she will start provisiong fundage for this project, I have been known to spot some here and there <img src="/forums/images/graemlins/wink.gif" alt="" /> and her B day is the 18th so I think I can get this ready to go on some time in April if not sooner.
