Projects Need help to ID 8" rear.

I've been reading posts on here for years, but finally needed help and joined. My most recent version of my 31 Model A was started about 35 years ago. TCI frame, Total Performance tube axle, 351 Cleveland, etc. After spending all my money on the engine, everything else was pretty low budget. Even then, 9 in rears were hard to find and pricey, so I settled for an 8 inch. After sitting in the garage for 15 years, I finally retired and have time to work on it again. I pulled the rear drums tonight, and the shoes were covered in oil. The whole thing is a greasy mess. I don't think Brakleen is up to the task of salvaging these. Problem is, I don't remember what the rear end came out of ! (I bought it from the local Nickel paper. No Craigslist yet.... ) Twenty years ago I changed out the pumpkin to a 3:55 gear, so the tag won't help. Drums are 10 inch inside diameter, and shoes are 2 in wide. It does have automatic adjusters. Will that be enough to get the right part? The axle flange has "C60W5 and R or B" on it.

 

try 1978 Granada, see how far you get.

If it had a tag on one of the nuts holding the center section in, it would be easier to figure out. but most guys toss them, especially when changing gear ratios. Not thinking ahead that it will also identify the car the brakes came from.

 

Possibly Maverick

Photo's might help with identification.

Are axels 4 stud or 5.

 

Maverick is the best fit for a Model A, I would base it on that. My understanding is just about all 8" rear end brakes are interchangeable, Small bearing 9"rear brakes also work.

 

With the axle flange number starting with C6 could indicate that its from 1966, possibly Mustang.

Mid 60's 8'' rears had axle tubes that neck down, I think Ford stopped doing this in the mid 70's.

 

Maverick rears are 56" wheel mounting flange to wheel mounting flange.

 

my suggestion was based on finding an 8" application that had the 2" wide brakes, but I could be wrong.

Most have 1 3/4" wide brakes

 

Friend had an 8" out of a Granada that had 10" x 2" rear brakes.

 

It's 5 stud, no taper on axle shafts, and here's a picture of the axle end.

 

go get some new brake shoes for a Granada, see if they work.

 

It sticks in the back of my mind that I DID save it, but we moved last year , and a lot of old stuff got tossed......

 

Measure the drum , diameter and surface where the shoe hits when applying the brakes should define what size brake shoes are on the axle .

Measuring the width of the shoes is a better way to decide what shoes it takes. The drum is usually a bit wider, perhaps 1/4".

He has the old shoes, it's not a big deal to match them up at the parts store, assuming the parts store stocks the shoes that fit cars that old.

 

After browsing thru various models on the RockAuto site, there seems to be a bit of variation on wheel cylinder diameters, too. So it seems the best course is to take an old shoe and cylinder down and see if I can find a willing employee to start matching up. I can start with the Granada, then go to Comet, Mustang, Maverick, etc. There shouldn't be a HUGE difference thru the years on these; it's just that most application charts don't specify if it's an 8 inch or 9 inch. If I'm lucky, maybe I can uncover an old part number. Thanks for the help.

 

Do most of your matching up on rockauto, they list dimensions, you can measure dimensions. These days, I like to go to the parts store armed with a part number, as well as an application. There are still a few countermen who understand how to figure out what part you need, they're getting rare.

 

Lol on that Jim. I went into a parts store for a carb rebuild kit for athe larger buick nailhead 2 barrel and the young guy said it was not listed on the computer. Finally the manager showed up and grabbed the book and told him look .

 

your best bet is to clean it all up and take the brake shoes to a napa stor and hope they have an older guy to look it up for you my local napa still has a couple guys that can use a catalog Tom

 

10" x 2" rear drums were pretty much standard on all Ford 8" rears except for some of the heavier intermediate cars in the late '60s/early '70s. Wheel cylinders on the other hand varied from car to car, although there's not a wide range of sizes. Keep in mind that Ford didn't use the 8" behind anything bigger than the 302 or in any full-size car, so asking for rear brakes off nearly any small V-8 powered small/intermediate Ford product in those year ranges should get you what you need.
