My brake project has become more of a project than I expected (broken bleeder screws, bad hoses) and I've decided that since I will be towing heavy that this is probably an opportune time to eliminate one set of drums (the middle) and add a set of disks (the middle as well).
I'm looking at the TSM Manufacturing kit, but am worried about the size of the calipers (look like 60mm to me), and am unclear on the "Cadillac" conversion.
Suggestions/comments/input would be greatly appreciated.
Thanks!

that is the good news, this will let you keep your original master cyl. and
give your 300lb more pressure, and more clamping pressure at the
caliper.(see charts - thanks DaveM)

the best of all worlds, OEM master cyl, more pressure, and easier /
cheaper to make the change.

Dolph,
To possibly help in deciding what approach to take regarding upgrading you mid axle brakes , You might want to check our PDF on our website regarding disc brakes. The website is www.bdub.net/branscombe "Disc brake improvements" The Lambke forked caliper mount for the Toro / Eldorado family of calipers in the most rigid mount available.
Pay particular attention to slides 120 to 134 inclusive. We are running 6 wheel disc brakes with an OEM master cylinder , ie. two sets of 80 mm calipers and a set of 66 mm Kelsey Hayes PB calipers. Also to keep in compliance with DOT / SAE conventions you will have to go to a P30 type master cylinder OR place an auxiliary reservoir of the Pegausus auto racing type on your existing OEM master cylinder.

Take a good look at what Al is offering. He knows the braking system inside and out.
