Dia-Compe replacement quick-release for rear brake

Has anyone bought one of these from Porkchop and installed it? Can I use a hammer and an anvil to smash rivit? Or a press is the way to go?

Re: Dia-Compe replacement quick-release for rear brake

Why? Wouldn't you want an exact replacement?

Yep, just go to a machine shop and have them press fit it if you don't feel comfortable doing it yourself.

Re: Dia-Compe replacement quick-release for rear brake

Is there a reasonably priced tool you can buy that will do this?

Re: Dia-Compe replacement quick-release for rear brake

I have been looking into this myself. I purchased to sets and have not installed yet either.  I have researched solid rivets and it sound like an air hammer (rivent gun) is the tool to use but have not had the time to try it.  I need to try it on some chi lee but I'm too cheap to even ruin those pups.  I live rurally and always try to do things myself other than traveling to have it done.

Re: Dia-Compe replacement quick-release for rear brake

Right i got a Nippon here that i wanted to put a quick release on
I got a snap rivet tool (1/4") from ebay and the bits from porkchop.

http://i659.photobucket.com/albums/uu313/wildon1974/DSC00228.jpg

I got the hammer out and lined the rivet snap on top of the rivet that i placed through the hole in the caliper and gave it a few smacks...

http://i659.photobucket.com/albums/uu313/wildon1974/DSC00232.jpg

FOOKIN FORGET IT!!!! �  ... � no chance are you going to set that rivet with the tool and hammer .. it aint happening.

So i have a friend that for some reason has a large industrial press so i go over there today and give it a go.  Still had to use the snap rivet tool with it ... worked a treat!

http://i659.photobucket.com/albums/uu313/wildon1974/DSC00246.jpg

the quick release is now on, working perfectly and is going nowhere...

It's not a good a finish as the original but you'd never tell unless you were really inspecting it.

So yes.... you need a press and one of the tools i got from ebay .. the tool and hammer won't touch it

cool

Re: Dia-Compe replacement quick-release for rear brake

Seems like 'a lot' of work to go through-to say nothing of the extra
expense involved-to put a quick release on a caliper that wasn't made
with one originally!

     My question is...'how do you break a quick release lever in the
first place?' The levers always worked easily & quickly on the DC brakes
anyway...breaking one seems 'pretty hard to do' with normal useage?

     If it were me,I'd rather replace the entire caliper for several reasons,
you'd have an original caliper with it's original quick release lever in
place...you'd save the 'extra' expenses involved...and you'd have the
entire DC brake-minus the quick release-for 'spare parts!'

Re: Dia-Compe replacement quick-release for rear brake

I wouldn't do it to a brake that wasn't originally made with one. 
A lot of calipers had the quick release removed when reconfiguring them for potts mod.  also i have a few brake sets that i'll be doing this too as the q/r have rusted quite bad.
I doubt people will be replacing these due to a broken part.

Re: Dia-Compe replacement quick-release for rear brake

I think its basically for the "look" .  I myself am a penny pincher to say it nicely and my adjusters chrome was not looking as good as my new powder, and the tool I can make for free.  I buy other people trash and fix it instead of dropping $$$ on NOS.

Anyway...

Wildon could you post a pick of the work end of the tool?  And how big of a press did you use?  I need to get a press to press out my Pro Neck stem and push in the new stem.

I've got a few more to do so i'll take some pics of the process.  The press i'm using is a large industrial thing though so you may have to go find a machine shop

Re: Dia-Compe replacement quick-release for rear brake

Well, I believe for every application there is a proper tool.

Would this work?

Re: Dia-Compe replacement quick-release for rear brake

A few notes:

1. The reason there isn't a threaded bolt is b/c a special bolt would have to be made that has an unthreaded portion so that the QR still WORKS. You can't just bolt this to a caliper - it has to be able to move between "locked" and "unlocked" positions. And there isn't a standard bolt I know of that has such a small unthreaded portion that would allow the QR to pivot.
2. I have had one customer install one using a hammer.... and says it worked great. Personally, I think a press would result in a much more factory-like look, but it all depends on how important details are to you. If the idea of installing one of these seems ridiculous and bizarre, then this product was never meant for you....
3. As has been stated - the main reason people want these are to replace rusty original QR's. I've made these available so people could restore OG brakes to new condition. With the new pivot bolts I've got coming in a few months as well as two style of anchor bolts and a few other parts, combined with the adjusters I already carry, you'll be able to completely rebuild/restore a DC brake with real DC parts.

If you're looking for a cheap press, Harbor Freight is about as cheap as you can go:

But personally, I'd get something beefier so it can be used for other purposes... like automotive - this is about the cheapest 6 ton press I've seen:

Re: Dia-Compe replacement quick-release for rear brake

Thanks for all the feedback Porkchop!!!

This thread is gold for me. I've been looking at the quick release on your site I have been hesitating because I had no clue on how to install this.

Re: Dia-Compe replacement quick-release for rear brake

Funny.... I hate the quick release and always grind them off on my brakes.  I just think that brakes look "cleaner" without them, and I've had issues with the QR "releasing" when I dont want it to....

To each his own, I suppose!  cool

Does the press your using hit the rivet tool quickly?
Or is it a press where the pressure slowly increases onto the rivet tool, similar to a floor jack?

Re: Dia-Compe replacement quick-release for rear brake

Knew Porkchop would be in here soon.  I bought these from you awhile back before finding out you were on this forum.  I have researched the whole solid rivet installation subject.  And it seems that rivets can either be pressed or phamatically hammered in place.  Pressing seems the most controlable though. 

I have been checking that press out for a few days now and I'm unsure if that would be enough.  Maybe Wildon could best anser this question once he posts pictures of the press in action.  I also need the press to rebuild a pro neck stem.  If it turns out it will be enough I will probably be getting a press for Christmas:)
