As far as i know, C-Rec with the Deltas were supposed to be the full-scale replacement/successor for the superrecordo, and they kept the older SR alongside it in the catalogue based on early pro riders feedback. but i stand to be corrected (now that i think of it, "C-Record" may actually mean "Crono Record").

I like it! I just use (used) dikes... but they’re never sharp enough.. definitely going to have to try the dremel

Early "3" pivot (2nd gen?); and 5 pivot; I do not know the specific generation of either.

Delta Brake "Lock-up", Dirt Intrusion
One thing that I do not really like about my Deltas is that they have a tendency to collect a lot of road dirt and grit inside their casings. I still remember how long it took for me to flush out all the crap in it when I was cleaning it after I just acquired the brakeset. Modolo (Kronos) and Weinmann (Delta Pro) had a good idea of providing a full rubber cover on their Deltas, that mostly sealed them from road detritus and moisture....
To prevent dirt, etc. from entering the unit I have taken some foam rubber and installed it internally, it's not perfect, but does prevent the majority of debris from entering and makes cleaning much quicker; usually just very fine dust enters. As yet, this has not affected function.
I had not heard of the brakes potentially "locking-up" so I experimented on my early "3" pivot unit and I could not duplicate anything close to that condition. I don't know if this can happen to loose/worn assemblies, my "scissoring" mechanism is tight without any undue play; but regardless, it is impossible on my set because the lower "scissor" impacts the upper "scissor" not allowing it to achieve an "inverted V". I believe my set is a Gen.2, so I'm curious as to how this would happen on later versions.

When setup correct, they stop as good as other brakes.

its a bit hard adjusting brake pad clearance to a specific rim that way, especially if one is too lazy to remove the tire.

Back from the dead!
Found this thread while researching if anyone is using Kool Stop pads for their Delta Brakes. Needless to say I found this thread pretty amusing to say the least.
All I can say is that the one on my Lemond seem to work just fine with what I expect is the original pads. I really can't complain about how they have been working for me. I'm looking for new pads just because of the suspected age of the ones I have.
I'm pretty sure the kid at the LBS that set mine up had never seen them before but I did provide instructions. Either he got lucky or that aren't the "terror" to setup that so many think.
I get those that may think they're ugly even if I don't agree. But those that say they don't work seem to be wrong based on my experience. And I don't even have the new and better 5 pivot ones.
Anyway, this zombie thread was too good not to revive. :-)

Maybe it's about time a new thread from the truly dark side of Delta style brakes is started.....
A thread all about Modolo Kronos Brakeset......

the earlier image from steel-vintage is for those not well versed in esoteric Shimano, the 600AX. The Dura-Ace was all cast alloy but as Chombi mentioned, not top tier finished.
From a mechanical design perspective, they should have been a winner.
(actually I think they were a near mechanical copy of a brake set out of Seattle that ran a small advert in the early 70's Bicycling! magazines).

Note in Gary's image, at least two versions of caliper, and three versions of lever.
(I think that is the bulk of them)
Note the variation in clearance.
He has set them up correctly where the side upper arms are flush with the main body, not sunk, not proud. Good work.
Where these get tricky is that the optimal mechanical advantage is in a narrow range of the mechanism, go outside that and curious results.
Wear the pads too much, less power.
not toe them in properly, noise.
(easier with the later holders that have an allen key set screw to assist in toe in.
A brake for the watchmaker capable mechanic.
Soldier the end of the fresh wire before cutting down to length just at and beyond the pinch bolt really helps, use flux!
Stainless cables? Silver soldier.

If they are so junky, I'd offer $75 for a mint complete set - help you with your cleanup tasks. I'll take one of those junky sets of C-record hubs, too

I did my fastest 40 miler of the past two years on the Lemond that has these. Somehow I did survive despite a couple of incidents that caused me to hit the brakes hard. My pads do seem pretty hard though so I'm thinking I'll play it safe to get in some new Kool Stops. Thanks for the confirmation.

For me, it's a matter of comparison. I have the most modern braking setups (to include disc on some) and the vintage brakes are "in your face" inferior in every regard. The modern rim brakes are really, really good for example.
I ran some Deltas a few years ago, and they were ok for around town stuff, but once I actually hit the mountains and actually HAD to stop, it was bad. Granted, just about every vintage brake setup leaves a lot to be desired by today's standards, some remain ok. I would never class any iteration of the Delta in the "good brakes" category.
