Rebuilding a 1980 Low Rider, 80" (with the SHOWA front forks). I'm looking for options for different front brake calipers abd discs. Besides NOS or VTwin Mfg, and without spending a million dollars (sorry PM) what are my options? Am I limited to the 10" disc? I'm open to options that require different caliper brackets, so long as I can buy them. I'm not a metal worker so fabbing my own isn't an option. And I'd prefer to not have to change my hub. Recommendations?
Replacing Front Brales on 1980 FXS

Here is a discussion thread for FXR brake upgrades - 1985 (similar?), which may have a few options or things to consider: "Check the history of this site regarding the FXR brake upgrades. This subject has been previously discussed, and there are some helpful threads",

That's a great read but a very costly swap... It is different but it is an option...Comment

The cheapest option would likely be a front end swap. 39mm front ends come up for reasonable prices and there’s a lot of options for adaptors to rub Japanese calipers or the 2000+ Harley calipers.
If you have your heart set on a 35mm front end, the 84-87 ones used the same calipers as the 88-99 39mm front ends and have the same adaptors available. Fab Kevin makes some, there’s some fandoms on eBay and there’s the Still Kickin’ Moto one’s.
If you find a 2000+ front end, those calipers are already pretty good.Comment

No. As far as I’ve ever found, the 77-83 calipers are it. Or very expensive replacements. I’m saying that the 84-87 calipers are the same as the 88-99 calipers. The difference is 84-87 is 35 mm like your current front end and the 88-99 is 39 mm. I know some people prefer the 35 mm forks for aesthetics or whatever, so I mentioned the option. The 39 mm forks are better but look newer because they are.Comment

Gotcha. So if I went thiis route, it would require swapping my forks. That’s something I’m trying to not take on right now. I’ve got a lot more to do on this rebuild and the forks work well and don’t leak. So I’m just cleaning them up, popping in Progessive springs, changing the oil and moving on to other parts of the bike that really do NEED rebuilding. I may swap forks down the road, but I’d like to avoid it for right now.

Still worth the exercise to ask the question, do the research and learn! Here’s hoping I can successfully remove one of them without destroying it (both bolts are stuck and stripped). And that I can successfully rebuild them. They were not behaving well when I started the project...Comment
