Round swingarm and disk brake?

[hoginedgewood]

Thinking out loud, I like the look of the drum brake, seems to function good. If I change to disk would I have to weld a tab to anchor the caliper?

When I changed the 72 I just picked up a square swingarm. But if you like it and you got good brakes why mess with it. I wish I never had and someday gonna put the round one back on.

Explain please.

Explain please.

I had good stopping power with the drum and never had any trouble but I thought I wanted disc. And then went through a couple year process with different calipers. Started with a 4 piston jay brake. It was ok but the pads didn't last worth a shit and they cost 60$. ( I've since found them cheaper and running it on the 81. )So I said screw this and went to a banana. I didn't have a lotta success with that either so finally got a GMA which is good but had to get a new 5/8 MC. And that's what's on it now. So all I'm saying is woulda been a lot less hassle to just leave it alone. And I realize pros and cons sprockets etc. And of course the most important one of all. "The cool factor ". Smiley face

I recently swopped over from box section s.a. + disc/banana to a round s.a + drum. like you I like the look, plus the drum is good enough.
at first I wanted to fit the r.s.a. and disc-wheel, as my drum wheel setup wasn't quite ready.
with the r.s.a. fitted I checked out to see if the disc-wheel with a banana caliper and oem caliper bracket (boomerang style) would fit.
I found the caliper-bracket fouled on the r.s.a axle-castings etc and simply would not fit. a gusset on the inside of the axle casting fouled the caliper bracket.
It wasn't going to happen in my book. I sorted the drum wheel out instead.
I guess it'll work with alternative calipers/mounts though?

Fab kevin has thee transition adapters , and yes ya need to figure out a caliper anchor, search here.
I did a thread askin about the setup years ago.

Something I did Years ago...Not likely to do it again... the Spacers was Not that big of a Deal... Look at the Spacers on an old Ironhead for inspiration... and use a Mill would be better than using my Angle Grinder and Files!!!! One of those 3 piece Clamps was my solution for the Stay arm... maybe Not a Great plan... But fully Functional!!!

I am curious about where you get the brake pads at now. I run this caliper front and rear and yeah, it hurts when it comes time to replace them.
Thanks, Brian

They're GMA F pads. Ebay $43. is about the cheapest I've found.

Thank you Hersch for the information. I am just now finding out the info from you. I got sick shortly after posting my question and ended up in the hospital. I came down with viral meningitis. What a nightmare trip this has been for me. Wanted to let you know that I do appreciate the info.
