Ok folks here are the results of the RAM MAN disk brake conversion on a 1964 Plymouth Barracuda. Car started out with Power Brakes 9 inch drums. 14 inch 5.5 rims
What you get in the kit is everything needs to complete the conversion. Everything is from a 76 Dodge Dart system (brand new)
Spindles (Doctor Diff upper control arm sleeves for small ball joint)
Rotors (Machined down for Small bolt pattern rims 5x4)
Calipers (slider style)
Hoses bearings etc.
So it all went fairly well, I kept my original master cylinder so all still looks stock (I did pick up a Kelsey-Hayes master with the extension on top, still thinking of using it or not)
Spindles get reversed so calipers are in front (still don't know why this is).
The Good, it does work. The Bad you need to grind down the caliper some and/or use spacers, I currently have been doing grinding and using 3/16 spacers.
I am currently not running a rear proportioning valve; Wayne the owner said drive it and see if you need it, so far its 50 50 rears always lock up first but you really got to mash the pedal. I may go back and put one in the future.
Master Cylinder, ok after months of research before mod here it is. The bore is the same for power and manual, disk or drum. Difference is a residual valve in the front spring for drum cars disk cars have it removed other than that no difference. There is some math to be done, so with the big calipers, the amount of movement helps residual pressure bleed of on the rears so right now I don't feel the need to have one, but once again in the future as I put miles on a may, currently I only have about 30 miles.
All in all it was a good conversion, however, Wayne did not tell me that I would have to grind and use spacers, and I told him the rim I was using, my car is all stock, just getting older and would like disk brakes. I did have a set of Mag Rims (14 x 6) that I may put back on to see if I need a spacer.
I would recommend this conversion to other folks, except do it yourself through a Junk Yard or here on the web forum there always seems to be someone selling the right parts. The only thing you will need to do is machine rotors as in 76 Darts were already 4.5 unless you are switching your entire car.
