Help needed to identify and repair juice brake system

[1915ford]

I bought this 22 centerdoor from a freinds estate and he
Had added juice brakes back in the 1990s. Can anyone id this setup and explain what the missing pedal linkage looks like? Its on there so might as well hook it back up. Thanks.

The brake master cylinder is actually a Honda Clutch Master Cylinder for certain early years with manual transmissions.

They are still available for under $50.

I recently bought one, and I can find the details if you need them.

I found the details!

TechniBrake made that brake kit many years ago.

That Brake Master Cylinder is for a 1978 Honda Accord Clutch Master Cylinder for a manual transmission. That unit was made by Bendix, Tru Torque, Beck-Arnley and another company. Only the Beck-Arnley unit appears to match the units I have seen and photos. Bendix has dis-continued sales and production. That unit is still available for $41 and a rebuild kit is available for $16 from Beck-Arnley.

This photo actually answers your question explains your pedal linkage better.

The brake pedal has to have a link welded below to actuate the rod that closes the cylinder and apply the brakes.

The small center rod section has a short link that actuates the brake switch there.

Many many thanks Jim. I knew there had to be another one out there somewhere. More worthwhile to pursue now that i have an idea where to get parts.

Here is a PDF file the instructions that came with the brakes originally.

I'm led to wonder why the hydraulic brakes were ever deactivated? Hopefully, they're in good condition...

I know. I remember him saying he wasnt impressed woth them years ago. Could be all stuck by now.

The system worked good maintained with the correct lining and functioning wheel cylinders. In the beginning he made custom aluminum wheel cylinders that were difficult to rebuild and were not off the shelf. Later versions used standard drum brake wheel cylinders that you could replace with ease. The replacement brake lining can’t be too stiff and the wheel has to be oil free and with no leaks into the cast iron drum.

“After reading several questions and comments regarding the Technicore (Techni-Brake)system, I feel an informational response is in order.
Roger Lee of No. Dighton, MA.developed this system. Roger was an automobile enthusiast his entire life. He restored his first Model T in the early 1950's and the first Model A in 1956. The second Model A, restored in 1962-1964, won first in class at the 1964 Newport Motor Car Festival, and was Feature Car of The Month in Hemmings Motor News Volumn 13,Number 6. He owned many Model T's along with a 1932 Buick Touring and a 1936 Ford Phaeton. He belonged to, and was active in, MTFCA, SSAAC, AACA and MARC. Roger designed and developed the Technicore system out of his desire to dependably stop his own Model T without distracting from the appearance of his car. He was so successful in accomplishing this, that many friends and T owners requested a system also. He accomodated by starting a small company for the manufacture of these brakes. Roger was a meticulous toolmaker and machinist with safety, quality, dependability at a reasonable price, priority requirements for this system. I feel that his goal was met. Those that feel the system was "pricey" may not realize the costs involved. Of the 93, all new, pieces in the kit, 37 were made here in New England using casting, laser cutting, photo etching and machining technologies and manufactured to exacting tolerances. All items needed for installation were included in the kit, as well as concise instructions. Trips to the local hardware store or salvage yard were unnecessary.”

Roger passed in 2003. ( written by Robert Lee, his son) http://www.mtfca.com/discus/messages/29 ... 1193146987

The brake cylinders were very well made!

One detail I was never able to find was where those rubber components could be found for replacements.

I've seen a couple of these semi modern types of hydraulic brake systems for Model T. I think I understand why your friend wasn't impressed with their performance. For some unknown reason, folks seem to think that the T's braking system is flawed (the joke being, step on the brake pedal and the car responds with "I'll take that under advisement"), because of that small drum on the earlier cars (wasn't any better on the later ones either). But for the times they were originally designed for use in, they worked fine (25 to 30 mph), and would stop on a dime if you were moving less than 20 mph. Yes they were slow to stop, but then all the cars on the road at that time were also, so it was relatively the same stopping power as everybody else on the road with yours, per weight of whatever vehicle it was, because the brake systems were pretty much the same (no matter how they were energized)....drum and shoe. Which is why your friend didn't like them much....they can't stop a Model T on a dime (or a 200 dollar string of 20 dollar bills laid end to end either for that matter in modern traffic conditions). What would happen as you pressed down on the brake pedal (say in panic mode for instance...been there done that on PCH 1 no less), you'd lock up the rear wheels and once that happens you've no control at all! There is no controlling any car if the wheels are locked up! You'll go into an uncontrolled skid (and who know what or whom you'd hit along the way of such a skid)...Soo, what to do, well, you'd need to devise an anti locking brake system for your T, but even then there is no guarantee that your stopping power would be the same as a modern cars. The only thing I can think of that might make some difference, would be a 4 wheel system (like all the modern cars have...sort of). Doesn't have to be hydraulic, it can be totally mechanical and still work quite well.

Ever drive a Model A? They've a 4 wheel mechanical brake system, that works really well. I drove mine from one end of Califunny to the other (during the time I owned her) and had no problem with the car stopping whither on or off a freeway (yes a Model A can travel on a Freeway, she'll do 55 MPH stock!).
So what you need is something like a Model A's braking system that was designed to work on a Model T...there was such an accessory brake system sold through Western Auto. Can't remember the name of it, but the one guy you need to talk too, is Gene Carotthers, he has one on his 12 Torpedo. It's a mechanical system, but if you want to go juice, I suppose you could modify your present system to handle it....Gene's car (I think at the moment) is apart in his garage, ask for pictures of his brake system, so you can get the idea how he did it. Because he got a partial system at a swap meet and figured out how to make it work, so from his pictures you should be able to figure it out too.
