    first of all the tag is gone but on the center section there is a good number c7awc the pinion housing is guarded, and there are three ribs. the housing is somewhat round not a hump. maybe this will help it does have the small bearings, with eleven inch by 2 inch drums. 4.50 bolt circle. yes the brakes are two inch not 2 and one quarter. thats where I'm confused. humbly john!

    1967 or newer, from that number. But that's the center section, and since it is missing the tag, the center has been removed at one time, and it could be an older housing/brakes.

    late 50s had the 11x2" brakes, for example 57-59 wagon

    pictures are very helpful

    That's a smooth back '57 housing isn't it?

    Round back , large pinion seal, no self adjusters on the brakes. I would say real early version.

    looks like a 57. If the shoes are 2" wide then it probably has the big bearings, but pull an axle and see. I think the big bearings were used in Rancheros and Wagons.

    Picture of the housing end looks my small bearing '57, bet the shoes measure 1 3/4". Drum will be a bit wider for clearance.

    yeah, the drum is wider than the shoes, and the shoe width is what you need to know.

    By the way all brake components are fairly common and interchange with other cars of the era but drums are difficult to find. Lucked out and got some cherry originals for mine and located an NOS pair for a buddy but it looks like Kanter Auto Products lists new ones for both base model sedan and the wider wagon, delivery, ranchero and police models.

    You have a mix of years. The housing is 57 based on the shape and the pumpkin is 67 or newer based on the casting number. Self adjusters came out in the late 50s - early 60s.

    1957 Ford station wagons used 11x2 brakes and IIRC manual adjusters

    Another thing. I put self adjusters on mine, used all brake parts from 1966 F100 except drums. Top retaining pin is a little short for the extra bit the cable ring adds to the stack so I shaved a third of the thickness off the shoe retainers (will now need later T shaped ones to fit better with adjuster hardware). Can be done with a surface grinder or carefully by hand against a belt or disc sander holding the retainers with a strong magnet and Crescent wrench is a good thickness checker if you don't have a caliper handy.

    The quick way to tell if it has large bearings, backing plate bolts will be 1/2" (3/4" wrench size). Small bearings are 3/8 bolts.

    yeah, that too! thanks for the reminder.

    Edsel was the first Ford product with self adjusting brakes (in 58)....
     
  13. '57 was the only smooth back in '58-? ( the early '60s I believe) they had a dimple back rear. Let me see if I got as pic.

    Yep found one:

    260124-1296500872-da91a668565360a831e06dfd80eff8bc.jpg

    It could have any 9" chuck, you just have to relieve the earlier housings a little bit on the flange to get the 9" chuck in there.

    thanks fellow hambers, the bolts and nuts on bearing flange take a 9/16" box wrench. looking and researching as well and found a set of 1976 plymouth fury drums 11" by 2" would these work on the 9" they have 4.50 bolt circle?? humbly john!

    the center hole size in the drum is critical, so it centers on the axle properly. Also most drums have different offsets, so it may be the wrong depth to center the drum on the shoes.

    You can put the 10 inch brakes on it as long as the the brake offset is the same. IIRC the small bearing rears, 8 and 9 inch were all 2 1/2 inch offset.

    The center register hole will be the iffy part, Currie makes adapters to go from the small to bigger.

    As I mentioned all brake parts should be able to be had new, haven't called Kanter myself but they list new drums part number 04014L BD 2613 at $122.00 a piece. https://www.kanter.com/productdetai...57&CategoryID=6&ProductCode=35&Router=Catalog

    Also later brake kits most likely won't work as '57, 8, 9 Fords had a different flange offset on the axles. At least with the base model narrow brakes, not sure about the heavier duty wagons, ranchero, etc. Would have to change to later style axles too.
     
  22. Looks like '57 housing and backing plates (adjuster hole up front). The narrow shoes indicate it was probably from a Custom 300. The axle bearings are most likely 2 3/8".

    I put 10" brakes from a 65 Mustang on a 57 rear axle. Everything bolted right up, drums and all.

    We've used maverick axles and brakes and cut a 57 housing to fit so we have a 56.5 inch wide 57 Ford 9 inch. We've also used 58 and 59 housings and filled he dimples and we've cut down 60 to 64 housings and welded up that ugly plug on them. We've also used two short 57 axles and cut one side down to fit to narrow a 57 which narrows
    it 2 3/4".

  25. Hell Jim, I was just throwing that out there for clarities sake. A lot of fellas don't know and I only know by accident, like most of the shit I know. ;)

    Answer me this take a closer look at the pics is that the car housing or the pickup housing. I can never remember which is which.

  26. I'm no expert about Ford 9" differentials but I'm pretty sure it's not a 57 since the 57 is the only year with a drain plug at the bottom of the housing.

    probably a car housing since it has the small bolt pattern axles.
