Lots of traditional rodders use the F100 brakes on early Ford spindles (1937 to 1948). Here's HOW I DO IT. I am sure there are other ways. I use 1953 to 1956 F100 hubs, backing plates and drums. They have the advantage of self-energize......or they help apply themselves. They are 11 inches in diameter and 2 inches wide ( so early finned Buick aluminum drums...will not work they are 12 inches in diameter ). The early Ford (37 to 48) hubs and the F100 (53 to 56) share the same outer wheel bearings and cups. Bearing # 09067 and cup # 09195 are the numbers. No adaptating needed here. You need # 14116 inner bearing to adapt the F100 hub to the early Ford spindle . The inner bearing cup (# 14276) works..as is. I always replace them NEW to prevent problems. You will need Victor seal #49195. Often times, a very small amout of grinding is required on the top of the spindle and the rear of the wheel cylinder where there is interferance on the 37 - 41 spindles. I have never had to grind a 42 to 48 spindle. When parts hunting, I will buy 66 F100 brake shoes and hardware. They are self-adjusting. The earlier ones are not. 1953 to 1966 F100 brake drums interchange. I buy them new but good used is OK (but hard to find here in the Southland). I only use 53 to 56 backing plates. They are easy to come by (all the Mustang II changeover guys will give you the JUNK they do not want ) Some rodders say that they have had to slightly grind the inner wheel bearing so that it does not interfere fit with the spindle. This may be true.....but I have never had to do this. I use TimKen bearings ALWAYS...... Also....by the way......bearing and race numbers are standardized. The numbers I gave for the cups and bearings will interchange....TimKen, Koyo, NAPA, Bower/BCA......all will fit. Seals are not standardized...... Heres mine....on the 32...... I like the F100 brake swap because it improves the brakes, they have the 5 on 5.5 early wheel pattern and it's old timey traditional. I realize that disc are better but this changeover was HIGH TECH back when I got the roadster...over 25 years ago. .
