Today while lookin through the local pick a parts for a dipstick i came across a 1977 Lincoln mark 4 or 5 (can't exactly remember) that was fully loaded (leather and all ) and it was in very good shape cosmeticly, but after lookin at the motor (main reason why I went over there) i noticed that the wheels where missin and that it had a complete ford 9" with disc brakes and all. Anyway i go and ask and i end up paying $100 for everything (canadian too) and that included the master cyclinder, proportioning valve, 9" rear end and all the brackets, etc. I will replace the calipers, rotors, and pads once i do the conversion.

Anyway what i want to do is to convert my truck (82 flareside, in gallery) to disk brakes. Now i know what to do to get the rotor to fit (the look like they have the 5.5 bolt pattern already, not sure though), and i know how to get the caliper brakets works to, my questions are in the master cycliner and proportioning valve. For the proportioning valve will this one from summit "http://store.summitracing.com/default.asp?target=esearch.asp&N=110&Ntk=KeywordSe arch&Ntt=%22Proportioning+Valves%22&x=14&y=7 work? If not could the proportioning valve from the lincoln work, or is there another choice?

My other question is with the master cyclinder (current one was replaced last year). With the larger capacity of the calipers vs. the master cyclinder will i need to get a different master cyclinder? If i do need a new one will a master cyclinder off a 1 ton HD (newer like 95-98) fullfil the fluid capacities that are needed or do i need a MC of a truck with discs on all four corners?

Thanks for any help (or hints tips and tricks to make this job easier as well as any pictures) I will post pictures up once i get to doing it(once harvest is finished).
