Are there any regular bolt mount dual pivot brakes?

Hi folks,
I have a 76 Eisentraut Limited with the original Galli brakes. Even with Kool Stop orange pads, they don't stop as well as I'd like. I have both dual pivot Shimano 600 Tricolor & late model 105s, but of course they're both recessed bold mount. Any suggestions or inputs?
Thanks & regards,
Van

Tekro R539 or R559, depending on how much reach you need.

Yes, these are your best option, depending on your reach requirements ^^^^

Also, you may not be able to find those brakes with nutted hardware, but you can buy the appropriate parts directly from Tektro at this link here and perform the conversion. It's pretty simple

OK, dumb question: will the Tektro kit work with either of my Shimano break sets?
Thanks again,
Van

You mean brake levers or other Shimano dual pivots to use conversion kit?
Yes to the 1st, likely no to the 2nd

I'm wondering why your brakes don't work well. Have your replaced the cables and housings with new lined housings and coated cables? That is a common reason for excessive friction (and poor braking) in the system. Have you taken the calipers apart and lubed the pivots?

I have done exactly this on a 1978 Eisentraut (nutted R539s front and rear) and a 1965ish Cinelli (R539 front, R559 rear, both nutted; (Italians did weird things with brake clearances BITD) . Excellent choice, especially if you swap out the original pads for some Kool Stops.

I run mine with Campy 10sp brifters, The combo works very nicely. I am a large person (255#) and most of my rides are hilly, and I have zero problems with this set-up

Are you confident they are set up properly? I have a 75 Limited with Campagnolo Record brakes and first gen Dura-Ace levers. It stops just fine, as fine as 40yo single pivot brakes will. If you're used to modern dual pivot brakes, I suspect you'll be disappointed.

​​​​​​​Whatever you do, don't discard those Galli brakes. Someone will want them.

Don't ever discard anything that may be rare, odd, obscure, even if broken, you never know when you may need the broken or non standard version for a pattern or example to solve a problem when the parts "expert" or someone trying to help says "this is the only kind i have ever seen, you must be looking for the wrong thing".

Surprisingly, yes. Tektro, Shimano, and Campagnolo all seem to use exactly the same design for 5heir dual pivot caliper brakes, right down to the size of the center bolt.

If you can find just the long center bolt for the front, that’s all you really need. They used to be available on eBay for around $5, but I don’t know if they still are. Anyway, use the front brake in the rear and it doesn’t need any modifications other than swapping out the nut. Then replace the center bolt on what was previously the rear brake with a long replacement bolt and use it in the front.

Pay careful attention to how the brake you’re modifying is constructed. There’s probably a set screw or two that needs to be loosened to disassemble the brake. If it feels like a lot of force is required you’re doing something wrong. It’s probably not stuck. It’s being held 8n place by a set screw.

The nutted Tektro brakes work very well - I've got a Raleigh with the 559's fitted (needed the extra reach as the 27" wheels were replaced with 700c) and they stop it very well. The levers are Weinmanns.
For information SJS Cycles have conversion bolts in stock: -

Thanks for all of the feedback

Sorry for the slow slow response. Things have been a bit hectic around here​​​​​.
I’m going to follow Andy K‘s advice & try to use my tri-color calipers.

FIW: The was recently reassembled with new brake cables after adding decals & graphics. The brakes work well considering the vintage, but with the hills here & my declining grip, I was looking for something better.😮 Cheers

Just a quick shout that you'll need to swap the brake shoes right>left when moving front>back/back>front. Basically reorienting the shoes so the open end of the shoe holder faces the rear of the bike i/o the front of the bike. Otherwise you risk the shoes self-ejecting under hard braking.
