Nutted Short-Reach Brake Calipers

I looked up Sheldon Brown's website and it tells me most short-reach calipers (39-47mm) have recessed bolts because the transition to short-reach brakes and recessed bolts occurred roughly around the same period. Is that true? I am looking for a pair of short-reach nutted side-pull calipers. Did/do they make such a thing? or should I stop the fruitless search...

If your frame and fork are skinny enough to take a nutted brake in the first place, you can almost unquestionably just buy the brakes and have a matching bolt found at the hardware store and be perfectly safe.

Thanks. But I am wondering are the centre bolts of recessed brakes generally shorter than those of nutted brakes? Comparing my pair of new Tektro brakes and an old Shimano 600 nutted ones seem to reveal this is the case.

Yes, they generally are - most manufacturers of recessed-mount brakes make "front" and "rear" ones, with the ones designated "front" having about the same length as a nutted brake designated "rear". Variations in the thicknesses of fork crowns and seatstay bridges are generally dealt with by having a longer recessed nut. I'm not sure what Frum's getting at, you certainly can't just use recessed-mount brakes on frames or forks not intended for them.

Regarding the actual availability of brakes, I believe Tektro make nutted brakes in most reach lengths, and it's also not that hard to drill out the rear of the fork crown and the underside of the seatstay bridge of a frameset designed for nutted brakes, to allow it to take recessed-mount brakes.

Check here fir the bolts from Tektro: https://www.tektro-usa.com/category.p...d=190&subcat=0
You can also pick up a set of their 800a brakes, seen here: https://www.modernbike.com/itemgroup.asp?IGPK=2126175524
I believe that you can swap the bolts from those calipers into yours, giving you nutted brakes. Price is not much different and you would
have a cheap set of brakes for who knows what other project.

Oh I see. I came across this on Velo Orange but they don't seem to offer short-reach versions of their nutted brakes. Any pointers everyone?

See post #5 for your cleanest solution.
Should you opt to use a recessed front brake on the rear, make sure that you reverse the pads. They are directional!

There are always plenty of nutted short reach brakes on eBay.

Thanks Airburst and Ronno6, I guess putting my front Tektro caliper on the rear is an option then!

Ideally, I am hoping to find a set of identical calipers to fit on the front and back so I was hoping to find some online. Do you have any brands/models that come mind? maybe something on the lines of Campagnolo, Modolo?

You will run across those as well as Shimano or DiaCompe, but most, if not all of those will more than likely be side pull calipers.
Those brakes up to the early 80's were pretty common in hex nut mounting.
Paul makes their Racer brakes available with hex nut mounting, but they are center pulls and cost a bit of $$$$.

If you want the effectiveness of double pivots, Tektro is pretty much going to be it as far as I have seen.

I have a number of Dia Compe short reach brake calipers with long mounting bolts if you're interested.

But there is a workaround for using new short bolts on older bikes.

The front brake is usually long enough to work as a rear, so that's no issue. (usually but not 100% of the time).

Then the rear brake with it's short bolt can be used as a front one of two ways.

1- drill out the back of the fork and get a recessed nut long enough to reach through the fork and attach the brake. (check availability of the nut before drilling the fork.

2- buy a long recessed mounting nut, cut off the head, and enough so it's simply a threaded coupler. Buy a stainless steel 6x1mm cap screw (tru-value) long enough to reach through the fork, ending a bit short of the brake bolt (if they touch you cannot tighten). Mount the brake through the fork, reach through and install your DIY coupler and spin it onto the bolt until ti bottoms against the fork (no need to tighten). put the cap screen into the back, engage the coupler and tighten as you normally would.

Either way you might need to do some cutting or filing to make an overlong part fit well, and remember that you want 5-6 turns of engagement (5-6mm) for good strength at both ends of the coupler.

Just the other day I put a pair of Tektro R539 brakes on an old Bianchi I built up last fall. I had been riding with the original Universal Model 77 brakes and my hands just aren't strong enough for old '80s brakes - took a lot of effort to squeeze the levers!

I got the R539 set from Amazon, $65 shipped.

R539 Tektro are great brakes; I own several sets. But, they are 47-57mm reach. The OP seeks 37-47mm.

I think I might be interested in the calipers. What I have done so far is I mounted the recessed Tektro brake onto the front fork using a nut tightened behind the front ofthe fork crown. The mounting bolt reaches flush to the back of the fork crown, resulting in a strange looking front brake installation as one can imagine.. So far (after 300km) so good. But since this is a DIY method I don't think this is a long term solution hence I am looking for some properly mounted brakes for my old style frame...

It sounds like your 2nd method might just do the trick, but since the Tektro's mounting bolt is too long in this case, I'd have to saw parts of it off? Right now I just don't have the bits and pieces but I am contemplating giving it a go!

Yeah, I am looking at the R320. Great brakes.

Sorry, I left an incomplete reply. Tektro R539 brakes may have just enough overlap to be a substitute for shorter reach calipers. I should have posted a photo of my front brake on the old Bianchi - the brake pads are all the way up in the arms.

Tektro's R559 and R539 brakes are both excellent. I've used them extensively.
