I looked thru all previous postings and gained a lot of info there. But I still do not know what I should or should not do.
As some may have seen on another post my car is a (almost) bone stock 57 Country Sedan with the original 312. The only known mod is that someone (not the last owner) swapped the column shifted 3-speed with a floor shifted 5-speed. The previous owner called it a T800 transmission from a Mustang. I cannot find any info on that. I know that the first 5-speed in a Mustang was the T5. Then there is the T45, the TR-3650 and finally the TR-3550. I hope to be able to identify what I have when I finally get to my car in a few weeks.
OK. Back to the subject. The previous owner claimed that the car has been fitted with a new simplex master cylinder plus all new brake parts in the stock drums. The cap on the master cylinder is not the same as on the photo that Guenter posted. Kind of a sign that something was changed even so both are similar rusty. I will certainly check all drums, hoses and lines when I get to the car, but since I only have a weekend to work on the car I need to plan ahead and order parts.
My buddy Jim drove the car from the trailer to his garage and finds the brakes to be "questionable". He was not able to go further as all that happened in nice cold Illinois with snow fall at that time.
The options are:
1. Leave the simplex system and the drums. Just make sure all works. Order replacement parts (master cylinder, wheel cylinders, hoses and all the small bits and pieces inside the drums) from Rock Auto as they are all dirt cheap and won't break the bank.
2. Just swap the simplex with a Duplex Master Cylinder. But which one is the right one ?
3. Swap the simplex Master Cylinder with a 7" or 8" PowerBooster/Duplex Master Cylinder unit. Here the options I found so far are:
a. the 7" unit from MACs with P/N 49-364518-1 for $439.99http://www.macsautoparts.com/ford_mercury_late/1957-1972-ford-brake-booster-master-cylinder-combo-475197.html
b. the 8" unit from MACs with 49-364516-1 for 439.99 (same price as the 7")http://www.macsautoparts.com/ford_mercury_late/1952-1972-ford-brake-booster-master-cylinder-combo-475170.html
c. the 8" unit from Summit Racing P/N SUM-760199 for just $149.97https://www.summitracing.com/int/parts/sum-760199/overview/
d. the 8" unit from MP Master Power Brakes P/N BM-15103-2 for $425http://www.mpbrakes.com/1957-ford-fairlane-booster-master-combo-kit-bm15103-2
e. the 8" unit from Dearborn Classics P/N 90-79281-1 for $430.95http://www.dearbornclassics.com/1957+ford+fairlane/power-brake-booster-and-master-cylinder-conversion-kit-fairlane-galaxie-ranchero-1957-1959.html
" unit from Classic Disc Brakes P/N 9786PV4-PV2 for $349 (but they claim it is just for a disc/drum or disc/disc set up)http://www.classicdiscbrakes.com/1957-67-Ford-Fairlane-Power-Brake-Booster-Master-Combo-9786PV4-PV2.htm
g. ... or buy one off eBay. There seem to be various sellers there like a place called Vintage Brake Solutions who sell you one for $179.95
4. Just go with a Duplex as described in above option 2. and add disc brakes up front. There are many different vendors. I like Wilwood.
5. Do the PowerBooster/Duplex Master plus discs up front.
Too many options. What would you do ? I only have one weekend to to the swap or have it done by some shop nearby Jim's house.
Again, I want brakes that will not let me down for 10,000miles. I do not fear to leave it all as it is as long as it brakes "kinda" acceptable.
I am puzzled !!!
