Thread: Buick brake drums

Tweet

Hey all,

I am building a Model A with 48 front axle. I have seen Buick brake drums used and want to know how it's done. Do they fit the spindle without special parts? Do they work with stock backing plate or Buick backing plate adapted?

Thanks Mike

Mike, most common method is to use '40-48 Ford backing plates, shoes, cylinders, etc., and then modify Ford hubs to fit the Buick drums (with a very slight bit of machining and redrilling the bolt pattern to 5 on 5 and 1/2) To do this swap, you want the hubs that mount on the OUTSIDE of the Ford drums, not the ones that go on the inside.

Now, a better alternative has come about. Wilson Welding is selling hubs that are made for this swap, and the cost is very comparable to using stock stuff, when you can even find it. What you do is strip the old Buick drums of their hubs and bolts, and then have the Ford bolt pattern drilled through the Buick drums. There is a steel spacer ring that goes inside, to which you tack weld some grade 8 fine thread 1/2 inch bolts to act as new wheel studs.

Wilson sells a cheap jig to do the drilling, but I found out about it too late. It cost me $ 175 at a local ripoff machine shop to have my Son's drilled.

Here is a picture of mine on '40 backing plates, and also my Son's on some nifty finned brake assemblies Wilson Welding sells. His have the advantage of being more modern, self energizing than mine.

Here is Wilson's website:

By the time you rebuild stock Ford brakes, the cost is very close to buying the brand new setup from them. But, if you already have the backing plate setup, this hub is the way to go. BTW, Buick drums are getting VERY expensive, usually about $ 400 a pair to get a good set with no broken fins and lots of meat to turn them.

Thanks Don..I didn't realize the hub would separate..too many years working with discs. lol mike

Good luck bud.

I used wilson hubs and f 250 53-56 backing plates. Both of yours are very nice . I like the finned b/p. I think you use the 42-48 b/p instead of the 40-41.

Thanks. No, you can use '40'41 too. They are the same, but have an extra adjustment to center the shoes. I have '40's on my '27.

Don, I like that front spring setup...behind axle with beefed up split bones. May be a way to lower my A a little more since axle only has 2-3" drop..longer wheelbase no issue without fenders.

What did Wilson charge you for the hubs?

The hubs were $ 225 per pair, and a complete seal and bearing kit was $ 125, so $ 350 for both sides. Admittedly, not super cheap, but really nice pieces, and brand new. They were great pieces to work with and install.
