My Factory parts manual shows that the 63 and 64 use the same front drum (Part # C3SZ 1102-C). I looked in a 1964 Thunderbird Shop Manual and it gives 11.090 as the diameter with 11.150 as the max diameter. I looked in the 1963 supplement and it matches the 61-62 manual when it comes to the front brake drum specs (11.06 max diameter). I don't know how long it would have taken me and how many hairs I would have pulled out before I remembered there is a supplement. I am now assuming the drum maximum diameter has a different spec in the 63 supplement because the 63 should have 11 3/32 (11.09) brakes, which makes the maximum diameter of 11.06 not possible. Those cars have 11 1/32 front brakes from what I can tell. Same thing listed in my 62 Galaxie manual. The max drum diameter in the 61-62 manual is 11.06. I have not got my brakes back together yet because I am trying to locate adjuster cables of the correct length, but soon I was going to be dealing with the drums. Now that I remember there is a supplement I am less confused about something else that I had begun pondering. If there is a different picture I will post it. I think I can get my hands on a supplement tomorrow. I did not even think about checking the supplement to see if there is a difference. The drawing posted by MMTX matches my 61-62 manual exactly (same image too (H1154-B). I am wondering how things finally turned out for TheThunderbird on his brake job last year? Did you ever figure out what the problem was? I don't know about everyone else's car, but my adjusting slot is towards the rear of the car. I think the backing plate is on the wrong side? This looks like we are looking at the driver's side based on the suspension parts and frame I can see. I don't think everything is flopped though. Look at the star wheel and the adjuster slot." I am surprised nobody noticed that earlier, and I didn't notice it until MMTX pointed it out. "I'm looking at your picture and your springs and everything you have put back is flopped. MMTX also added an interesting point a year ago. Like MMTX mentioned, the rear drums use the same return spring for both shoes. The spring is not pulling the shoe up or down, it just looks like that because the anchor guide plate (part just between shoes and the spring hooks) is not straight, which is of no significance. My manual has the same picture posted by MMTX. The adjusting lever is too low to be effective and the adjusting wheel is overextended to compensate for the cable slack.Īs far at the short red return spring goes, according to my shop manual, it is correct. Mine looks very similar to the picture posted by "TheThunderbird". I have been unable to get my cable sufficiently tight as a result. The cable in this kit is too long for 1963-1964. The popular Thunderbird place where I bought my cables has the same self adjuster kit (w/cables) for 1961-1962 Thunderbirds as it does for the 63-64. The 63-64 Thunderbird cable is 10 15/16" long while the other models mentioned have a 11 1/8" long cable. According to the OEM 1960-1964 Factory Parts Manual, the self-adjuster cable for the 19 Thunderbird is shorter than the cable for the 1960-1961 Thunderbird and the 1960-1964 Ford cars. I have done many brake jobs but this one has been a pain and I finally figured out why. Whoever did the brakes last removed all self-adjuster parts and had incorrect springs installed, so I am starting from scratch. Thanks to all who have replied and added their insight previously. I found this post very helpful while messing with my 1963 Thunderbird front drum brakes this weekend so I assume others are still looking at it for help too. I know this is an old post, but I wanted to add a little more.
