http://pg.photos.yahoo.com/ph/jjlstanley/detail?.dir=/1a34&.dnm=c0d0.jpg&.src=ph The rusty one came on my 37 or 38 frame. The black one I got at a swap meet this weekend and was labeled 37-39 Ford. The deminsions look the same eyeballing it, but one is two peice and the other is one peice. I ***ume they are interchangeable? What is the difference, anyone know? Does the two peice come apart?
My understanding is the '36 was mechanical with rod actuation like the earlier 5.5" pattern and those wide five's won't fit, '39 and up brakes, some conflict with some ribs or nubs that hit, and also have heard that can be turned and cut out to clear and be used. '37 and 38 were mechanical with cables and drums were the same and will interchange with 39 and any juice back plate ***embly to '48 The two piece could be originally on 37-9, no particular rhyme or reason for using 2 designs, can mix and match. The wheel bearing size was reduced in '36 and a sleeve installed in the hub. Haven't encountered that yet, any wide 5"s I've used interchanged and worked so far. I have found replaceing lug studs hasn't always worked out, had to use some aftermarket spacers to keep the nuts from bottoming out the threads. Some of the replacement stuff is foreign junk.
I think I've got all the mechanical/hydraulic and backing plate stuff down. The guy I bought them from said they would not fit his 36, which is what he bought them for. It's just that when I got these home they were a little different from my 37-8's, if that is indeed what I have.
Here's another version....these are EARLY '36. The fronts are one-piece similar to your black one except for the windows. The rears are 2-piece with windows but entirely different than any of the others.
I saw a set of those like the 36 front this weekend. Looking at them, the black ones are slightly taller over all when the surface where the hub cap screw on is down. The grove where the backing plate sets in is a little larger on the black on also. I guess I am going to have to invest in some precision measureing instruments. Anybody know what the maximum acceptable I.D. is for the 37-0's?
I have a question, I was gonna start a thread, but figured I'd just ask it here. Are 1939 ford p***enger car bolt patterns the wide 5, or are they a 5 on 5-1/2 bolt cilcle? I have the chance to get a full '39 front brake set-up, backing plates to drums, off of a driven car. One brake drum might be s****, but he says hes got another good one he'll throw in. He wants $50 for everything, are they worth it? And if they are wide 5, how hard is it to find rims? What size rims are available for the wide 5? Thanks in advance for any and all accurate answers to these Q's.
The original size for these drums was 12.00 inches. I'm not sure how much they can wear before they are to big(dangerous)but I've ran them on smaller,lightecars at 12.080. good luck

'39 Ford would have the wide-5 pattern if they are original. Dunno how hard it is to find rims over there, but you are limited to 36-39 Ford rims, or wide-5 circle track rims since they use the same bolt circle. The widest factory rims would probably be 39 Pickup. I am pretty sure you can also put 40-48 drums on if you want to get to the 5 on 5 1/2 bolt circle.
Just to confuse you (and me) I have a juice brake front end with both a ribbed drum on one side a smooth drum (one piece) on the other. These brakes came out of a running car that was driven alot. I dunno... Johnnyfast how's that disc set up coming?
I have rims in 3.5",4" and 5". According to an old timer, 3.5" were standard on V8-60 vehicles. 4" were common to everything else and 5" were on Lincolns. People have gotten pretty creative with the rims. I came accross a set of 4 that have wide five centers and 7" wide 15" rims. They are just perfect for the Hurst slicks I got from Marty at NW Speed Equipment. $50 is a good price for just the backing plates if they are "decent".
I'll be doing a "tech" thing eventually. I wasn't crazy about the first version and I have re-designed it slightly. My machinist has been travelling around the world too. He's back now and, once he's caught up with his own projects, I'll be bugging him to help with my stuff.
If you don't want them sell them to me. I need backing plates and all, and another set of drums. Or if you don't want to use the wide 5 drums I buy those from you for the 50 you need to buy everything if you'll get them measured to see how much over they are.
I ran across one web site last night saying a 12" drum could go as far as 12.090". It was not for any specific drum, just a generic number.
Any idea what rims would be used to fit the wide 5 centers? I have two wheels but the beads are to rusted to use.
Heavy, but to get the original "traditional stock car" look for my 37 this is the ticket. bought these this way, need to make 2 more. http://www.directimagehost.com/is.php?i=103520&img=DSC02527.JPG http://www.directimagehost.com/is.php?i=103519&img=DSC02526.JPG http://www.directimagehost.com/is.php?i=103518&img=DSC02525.JPG The drums I am told max is 12" + .060. They aren't re-poped yet, and any good ones are valueable, at least to those of us that like em. I p***ed a NOS pair of one piece fronts for 50 bucks at a swap, tapped out. Am sorry now, should have found an ATM. Probably will pay over a hundered apice when I have to have them. May come down to experamenting with spray welding or sleeveing them someday. Helps to re-arc them when drums are "out there" I am told, I haven't tried it yet, light car stops good with new parts so why screw with it, winter time thing to think about.
What is re-arc ing? I had not thought of doing the wheels that way, beats drilling out all those rivits. Thanks for the pictures.
1937-39 drums, front and rear, are identical. This type is listed to replace '36 rears. '36 fronts are different offset. There are numerous suppliers and differences in appearance. If part number prefixes are visible on hub, '36 would have a "68", '37-9 "78". I've never seen a replacement diameter spec from Ford--a late bulletin I have here has a column in the chart for this spec but it is empty! I'll see if earlier bulletins or Canadian ones have a spec. .060 is the common modern limit, and this would be a rejection limit in the absence of other info if you had to undergo some sort of official inspection. The things obviously function way beyond this, but I would say think about weight of car when deciding how much to gamble. Thin drums would be safest on light cars, and I wouldn't try a .100 on a '48 Ford!!
I do know my 36 stuff has a different offset in the drum and backing plate. The four bolts that bolt the backing plate to the axle are almost even with the outer edge of the shoes.
I'd like to find a pair of those 5" wide Lincoln wheels. I have two nice 4" ones I'd trade plus some cash...... Wouldn't the 5" ones be better with 7.50 X 16 tires ?
