Miyata 1000 cantilever brake replacement

I posted last month asking if all cantis were the same fit. Well I got lots of good info and went with Tektro CR720s. They fit like a glove on the rear but(as some mentioned) did not quite fit on the front. I had a spare set of Kool-Stop salmon thinlines but could not get them square even with the thinnest washer(3mm) setup. I have to say that illwafer, AEO and cycle mavern warned of possible fitting issues. So I cleaned up and put back on the old ones. They work but are nearing their end.
Options:
I think I can replace with Shimano Altus CT91 Front Cantilever Brake(cheap enough) and did fit illwavers '82 Miyata 610

OR is it possible to replace the 'spring' inside the old cantis. Looking at the cantis I gotta think this is the part that needs replacing...No????

AEO: thinlines don't work, at least w/ mine

I had a similar situation with my Raleigh which had brazed fittings located for for 27 inch wheels and was a problem with 700C's. A set of Shimano Altus brakes resolved the issue, but I had to run them to the ragged edge of their adjustability.


I really like the Altus brakes, they're cheap ($20) and they work. Both of my bikes have been upgraded with them.

balto charlie,

you had to make it difficult for yourself didn't you? just kidding.

if you go to your local used bike shop (i bet there are a few in your area), they probably have boxes of used cantis for a few dollars that work just as good as new ones. bring your bike in and try a few on and see what ones work the best. you can replace the spring, but you will want to find a matching pair because all springs are not the same, and at that point, why not just get the other pair.

lots of the old cantis have the same design as those cheap shimanos.

nice bike illwafer. When I originally posted all replies were positive for the Tektros 720s. AEO stated some issues but someone else told him to use thin line. Since I had the thin line pads lying around I went for the Tektros. You posted your info after I ordered my brakes. I remember thinking ...opps! I'm jst going to order the shim altus. I actually got the old ones working so am in no rush. If I could find a source of springs might just use them. AE has some but not Shimano, I believe they are Diacompe. I wonder if they will fit......

Nope, I bought the BR-R550 for my 27 -> 700C conversion, no dice. I was so disappointed.

the only ones that seem to work are the smooth stud low profile.
I have an older model BR-550.
