Well, girls and boys, it's finally time to sit down and put this info and pictures into a technical thread of sorts, in the hope that the info MIGHT help some of you address some particular issues I wanted to address on MY '40 Ford coupe. First, a little background. I've owned and built quite a few old Fords and also restored several old Corvettes over the past 47 years. Since 1964, I've wanted a '40 coupe but that just never happened until 1997 when I bought a street rodded coupe with a beautiful body. I knew that the underpinnings and details weren't what I wanted, and I've spent the past 13 years collecting parts and changing things to make this coupe into MY car, something like the coupe I wished I could have built around the '63-'65 timeframe. Anyway, one of the major things I wanted to change was the front brakes this car had on it. The previous owner had put Chassis Engineering disc brakes on the '40 spindles, which included the '70-'77 Camaro discs which had been adapted to the '40 spindles. Frankly, they never stopped like they should have because of a mis-match of parts to go along with the disc installation. One of my criteria was to end-up with 12" Bendix-type, self-energizing drum brakes that could have been used on a hot rod back then. Another of my criteria was to end-up with a 5 x 4 3/4" bolt pattern, as I wanted to run Chevy chrome steelies which I already had. In addition, I wanted to run a brake that was easily adaptable to the '40 spindles. SO......after not too much thought, the 45 fin Buick drums became a fairly obvious choice, not because of the "COOL" factor but because they are still available, they are 12" by wide, they ARE traditional hot rod material, and because they are obviously adaptable to the Ford spindles by at least two or three well-known methods. I thought about the "new" Lincoln backing plates. Also knew a little about the old mid '50s F-250-12" backing plates, specifically that they bolt-up to the spindles, and that they had been "adapted" to work w/Buick drums. So, I actually found two pairs of '55 Ford F-250 plates in short order. Sure enough, they bolt right up to the spindles, look good, all the parts are easily obtainable from NAPA, and they're actually authentic, old parts. Most, if not all, of the adaptations of these backing plates to use with the Buick drums that I had seen usually involved some type of interference between the plates and the lip at the rear of the Buick drum which required some surgery on the Buick lip to solve the interference. One well-known guy's "new" adaptive hubs didn't seem to solve that problem because his hubs mount the drum INSIDE the hub flange, moving the drum too far inboard, resulting in the drum lip hitting the F-250 backing plate. In addition, I wanted REAL studs, pressed into the flange...not spot-welded bolts. Also, I wanted the look of the drum mounted on the outside of the hub's flange, without all those other unnecessary bolt pattern holes showing. Plus, those hubs ain't exactly cheap, especially when ya don't end-up with exactly what ya wanted it to look like in the first place. On top of all this, the adaptations of the Buick drums to OLD FORD HUBS have their own problems, especially when changing the bolt pattern to anything other than 5 x 5 1/2". RIGHT NOW might be the time to tell all of you that IF you are not going after a 5 x 4 3/4" bolt circle, this EXACT process won't work for you, as you'll see a little later based on the EXACT HUBS we ended-up using. Keep in mind, I kept fighting with this "look", and the spacing problem with the Buick lip being too close to the backing plate. Still scratching my ass, I started measuring the "in-out" spacing, with regard to the wheel-mounting surface, of the originally adapted Camaro rotor disc. Hmmm, maybe we're on to something here. That surface actually sits farther OUT on the spindle than the same flat surface of an old Ford hub when mounted on the same spindle. Did some more quick n' dirty measuring on the Buick drum with the F-250 backing plate mounted and DAMN...this is gonna work. You say: What the hell is this idiot talking about? Picture a disc brake rotor in its entirety. It's nothing more than a disc which is glued onto the rear side of a hub, a pretty substantial hub, to boot. So I'm thinking, if we can cut the disc off of the hub, we can glue the Buick drum on the outside face of the new, disc-less hub. The Buick drum is now spaced-out properly to clear the backing plate, AND I also have the Chevy (5 x 4 3/4") bolt pattern I want already manufactured into the hub, with press-in studs...no welded bolts or such. Of course, there are some minor details that we haven't discussed YET with regard to properly mounting/adapting the Buick drum, but if you'll follow this thing through to the end, there will be mucho-plenty of pictures and explanatory BS to get the point across to y'all. My biggest problem now is that there is SOME machine work involved, both on the Camaro disc rotor AND on the Buick drum, and I ain't no machinest and I certainly don't have the equipment. I DO have a good grasp of the machine work necessary and how to approach this project. I live in the Houston area and one would think, correctly, that there must be a gazillion machine shops around here. So, I ended-up contacting three different shops. One didn't want to screw with this "hair-brained" idea. The other two didn't impress me with their ideas on how "simple" this little project would be to "throw-together". So, in the back of my mind I remember a friend in Salt Lake has a son I had met on a trip to Bonneville a couple of years back. The son is none other than Brian Thomas, aka HOT ROD PACKARD here on the HAMB. I knew that Brian was an accomplished machinest, and I knew that Brian understands "hot rod". So, I e-mailed Brian with a precise explanation of what I wanted to do, and why. He e-mailed me back and said only: "Send the shit. I know what you want". Brian is sometimes a man of few words, but believe me, HE knows his shit. I sent him a pair of new Camaro rotors, a pair of pretty nice (not worn-out...only .025" oversize) Buick drums and a handful of new studs. Brian put his heart into this project. Everything he did entailed precision, straight and beauty. Every step of the way, he was thinking nine steps ahead. In fact, these things ALMOST turned-out too pretty to hide behind a wheel. Follow along on this thread (I've never posted something like this before...bear with me) and hopefully, some of you can put some of this to good use. Please understand that HOT ROD PACKARD gets ALL the credit for this beautiful end product.
