I’m probably going to make a number of posts (of which this is the second one) about brakes on a banjo. In a nutshell what I need to do is come up with some braking arrangement on the Model A Banjo axle. I want either disc brakes or a Bendix type drum brake that can be mounted (perhaps with some minor modifications) on an otherwise stock Model A Banjo Rear and with a 5 x 5.5” lug pattern Without adding any width to the axle (I purchased the 12” Lincoln Bendix brakes but they add 1.25” to each side and I don’t have room for that on a full fendered build) A couple of things that come to mind as possibilities are the 11” Bendix brakes that were used on the 50’s - 60’s F100’s and some 10” Bendix brakes from a 60’s vintage Jeep. The drums would mount on the stock model A hubs. I have to think that there is a way to do it, I just don’t know how.. If I thought that some setup had a decent chance of working I would locate some thrashed backing plates and drums to use for mockup. Thank’s Y’all.
This is one way to get modern brakes and axles. Cut the ends off the banjo tubes and graft on ends from a 9" axle. Machine the differential gear carrier and ring gear to accept the larger diameter 9" side gear bosses. Finally, grind off the crowns and ends of the teeth on the 9" side gears so the mesh smoothly with the banjo spiders. Grind the 9" side gears smaller diameter and a bit off the crowns of the teeth that otherwise interfere with the shallower banjo spider gears. Otherwise, the two vintages of gears mesh perfectly.
I’ve been looking at the disc brake kits for the front of my 39’ Foed.. I want lie I like the idea of have a dual bowl master cylinder. I had a 57 blow a wheel cylinder in Texas. Luckily I had a good e brake. But I can’t see doing that much work on my rear diff. I think I’ll keep mine the way Ford made it. But i like seeing how people modify their old hot rods!
I don't see how the Zephyr style brakes wouldn't work or how bendix style are any wider than the original drums. The math isn't mathing here. Pictures in addition to your query would be leaps and bounds more helpful. Also there is no need to start a new thread every time you have a new question about the same thing.
Also there was a super in depth thread by a member probably within the last year doing a front to back installation using his own products and cannot remember who it was. The thread had a **** load of pictures to go along with it. I know @ukrop bought some of his parts for his build, specifically the parking brake arrangement that used a guide tube for the cable.
I have the repo Lincoln brakes on my stock ‘47 while using the stock style drums, it doesn’t extend the track width.
Found it, this should have all of the information you need. https://www.jalopyjournal.com/forum...aulic-brakes-and-steering-gear-setup.1327522/
The problem I see with this method is when you cut off the end of the banjo axle housing on a Model A it eliminates the rear spring perches and the wishbone mounting point. That kind of defeats the purpose of running the original rear end. I agree with dwollam There's nothing wrong with 40-48 rear brakes which is basically a bolt on other than a notch in the backing plate to clear the rear spring bracket.
Not much, if any of that applies to a Model A rear. The Model A differential is different than a V8 differential and what you are suggesting will not work. As stated earlier you will also lose the spring perches.
Here's a few different ways. I tried to find the EarlyV8 Garage step by step, but I think it was on their website. https://www.jalopyjournal.com/forum/threads/juice-brakes-on-an-a-rear-end-question.1035288/ https://www.lainefamily.com/ModelAFiles/ModelABrakeUpgrade.htm https://rodandstyle.com/blogs/rod-and-style-tech/adding-juice-brakes-to-model-a-part-2
I'm pretty sure there was a huge thread about this very topic here on the HAMB or the Ford Barn about 6 months ago. There are bolt-on and weld-on perches available. That's how folks use the later banjo rear ends with a stock Model A spring. That said, if someone is going through the work of replacing the axle ends, they'd be ahead doing it to a '35+ rear end rather than the A one.
