One thing I didn't see mentioned is making sure the pads are equidistant from the rim. If one pad is firmly against the rim but the other isn't it will make a racket until you squeeze harder - then it stops.

[RBW] Re: canti brakes
Lots of ideas here, and they're all right...sometimes. Paul cantis can squeal with the best of 'em. Cheap Shimano Altus cantis can work great with no squealing. So much of it depends on seemingly trivial details, and what works on one bike may not work on another. At a shop I worked at some years ago, we tried numerous adjustments, and every brake and pad we could find (even tried the pads backwards), on an otherwise really nice IF cross bike. Frustrated, we even tried a different rim/ wheel, and no luck. It was so bad as to be almost unrideable (when the ft brake was applied). We ultimately concluded that there was something about the fork that caused the squealing. As far as I know, that bike has a squeaky brake still today... But one generality that I can offer, which seems to be contrary to popular opinion, is that Kool Stop Salmon pads are NOT the answer to squealing, in general. I actually quit carrying the Kool Stop pads because I thought their fabled superior stopping power was mostly hype (at least here in the mostly flat, usually dry part of the country), and the finickiness with squealing was a common problem. Now we use budget Tektro pads that we can buy in bulk (no individual packaging to waste), which are, IME, as good as any, and seem to be fine on most brakes on most bikes.

[RBW] Re: canti brakes
I've always preferred the old full post style canti for their adjustability. My favorite has been the vintage Shimano BR-MC70 from the early 80's. Super adjustable(also good for 27" to 700c conversions), high powered and no squealing whatever pads I use. Some rear XC Pros with Ritchey(kool-stops) pads started squealing early in the year on one of my bikes, and despite my best efforts I couldn't get them to stop. So I throw on a pair of the MC-70 with their 25 year old pads and problem solved. Better stopping power too. These brakes also came stock on my Stumpjumper Sport and I always loved them for that bike . so I got a second pair of the MC-70's this winter for a song. I'm glad I did too. So . I have to wonder about all these pads marketed for squealing brakes. is it really the pads, or is it design of the brake? There's no absolutes but it's obvious to me the brake design is paramount. I've used various pads with my Stumpjumper over the years and none have squealed. The Ritcheys are/were supposed to be great for squeals but that didn't prove to be for me. A pair of the BR-MC-70 always pops up on ebay, they're nothing fancy to look at, and are inexpensive they just work. As far as new brakes . I don't know how you find a really good one, other than trial and error. Cantilevers will always be a challenge to set up because of the nature of having two independent brakes converging on the rim and cantilever mounts are often far from perfectly brazed. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.

[RBW] Re: canti brakes
Hi Seth, Another option here: My commuter/cross bike had Avid Shorty 6 brakes when I bought it - very similar to the BR550s. They stopped pretty well but squealed and shuddered badly. I tried a lot of different things - different pads, toe-in adjustments, different straddle cables, help from the LBS etc. I could minimize the problem but not eliminate it, and even when I got it to a minimum, it took a lot of fiddling to keep it there. I replaced the brakes with the new design Shorty 6s - the ones that are kind of triangular-shaped, as opposed to the lever-arm design of the older Shorty 6s and the BR550s. Problem Solved! I know that there is a bunch of alchemy involved with brake squeal - harmonics, fork flex, pad compound et al, but this change solved the problem for me. Stock pads, normal toe-in. The stopping power of the new design seems to be somewhat less than the old ones, but I considered this to be a minimal trade-off.

[RBW] Re: canti brakes
Setting up canti brakes is as much an art as a science. Before jumping to another brand of lever or brake, it's always worth it to play with the pads and straddle wire. I've found that the geometry of a given frame and differences front to back will affect how the brakes work and how they must be set up. For example, my shimano BR550's work wonderfully on the front of my Quickbeam, but not on the back even given the same levers, same straddle wire set up and even "better" pads in back. Hmmm. The IRD's work really well on my Atlantis, although the supplied link wires (substitute for the yoke and transverse wire) were too small and I had to swap those out for 93mm wires front and back. By the way, I almost always prefer link wires as opposed to yoke/transverse wires - you have to buy a new one to change the mechanic advantage, but they've always seemed to offer better braking than the yoke/transverse set-up. Now, there is ONE brake that has consistently worked on EVERY bike I've tried it on. The Avid Single Digit 7 with Tektro or Cane Creek drop v levers or any linear pull flat bar lever is easy to set-up and offers EXCELLENT braking. I use traditional canti's out of nostalgia or for aesthetics, but the Avids for actually stopping heavily loaded bikes in challenging conditions (Big Dummy cargo bike, Bombadil MTB/ Touring bike, etc.) DC On Oct 11, 4:29 pm, SpeedyChix wrote: > I like the Paul Touring cantis & the salmon KoolStop pads.

[RBW] Re: canti brakes
Had a similar situation with one of my bikes. The only thing that worked on this one was a different brake. So it now has a Tektro 720 on the front. These are also the brakes I use on the Sam Hillborne and they are very reliable with no squeal. At least for me on two bikes. Now, the mechanic who did the brake switch also recommended different brake shoes. Not just pads. Many cartridge pad holders are pretty loose on the post. Which can add to squealing tendencies. My Atlantis has Paul brakes. They are the bee's knees. But expensive. Found the initial adjustment to be easy. But still a read the directions type of setup. As to brake pads, my wife's bike uses Yokozuna pads from Rivendell. She likes them more than the Kool Stop. I believe they are based on the old Mathauser compound.

I like the Paul Touring cantis & the salmon KoolStop pads. If you get the v-brake pad holders for them it's even easier. Slip in the pads, line em up and tighten.

[RBW] Re: canti brakes
I'll echo the above suggestions to try some new pads first. But I'll also vouch for the IRD's and Tektro CR720's if you decide to go that route. I had the IRD's w/ KoolStop pads on the Atlantis. They worked great and were fairly easy to set up. I run the Tektro's on the QB, and I'm super pleased with them. They have a nice feel, stop as good as any, are easy to set up, and come with a super nifty straddle wire hanger. And they're cheap.

[RBW] Re: canti brakes
If you want to do something different, I just got back from a camping trip with newly installed Paul Motolites. The brakes stopped under load (about 75 to 80 pounds of gear with 165 pounds of me) well. Using drops so brake levers are Cane Creek V Levers. Tektro and Dia- Compe also make drop bar V and mechanical disc compatible levers. I did not experience any squeaking. Motolites - for me anyway - are somewhat difficult to set up. No maintenance problems on the ride at all. On Oct 11, 12:50 pm, Seth Vidal wrote: > I have a set of the shiman br550's on my bike right now and I'm not > terribly pleased with them.

[RBW] Re: canti brakes
Those brakes have some of the worst brake pads I have ever experienced. They came on my Quickbeam. I immediately replaced them w/ Koolstop blacks (Sunny SoCal!) and the performance was doubled if not tripled. A little bit of squeak no matter what I do, so I think it's just the inherent flex in the cheapie brakes. If I had the $$$ floating around, I'd replace them w/ some Pauls, but I can live with the small amount of squeak.

[RBW] Re: canti brakes
"Persnickety to setup" certainly matched my experience w those brakes. What levers are you using? I found them almost impossible with Ultegra SIS. I had to set them very, very close to the rim to escape bottoming out the levers, then there wasn't enough room left to open the straddle cable. Any little thing bumped them out of this tight alignment. Salmon pads and lots of toe in helped with the screeching and improved the stopping. Then I swapped out the Shimano levers for Cane Creek, which made setup a lot easier because of the added QR. Ultimately I bought a pair of Paul's Neo Retros and felt like I had gone to canti brake heaven. Cane Creek levers, Paul's calipers, silver bar end shifters make me a happy rider. I don't think I'll ever change. I know Paul's are expensive but they are a lifetime item.

[RBW] Re: canti brakes
Yeah, it seems like whether or not canti's squeal seems less to do with the particular brand/model of brake than the peculiarities of the set-up- all the stuff jim said, as well as the flexiness of the fork, how worn your cables are, distance from housing stop to straddle wire, phase of the moon, etc, etc. Putting a brake booster* on my SUPER flexly after-market fork went a long ways towards minimizing squeal on one of my bikes. So i'd play around with them a while before springing for a new set. Also know that as canti brake pads wear, the angle at which they contact the rim constantly changes, so while you may have had them perfectly dialed in a one point they may no longer be- this is just a function of canti geometry and is the price we pay for fat tires and arguably stronger brakes. Read Jobst on the subject for more. *e.g., http://paulcomp.com/brakebooster.html. That's just an example though, there are much cheaper/less clunky looking ones available too.

Now, I'll never step in front of someone looking to buy new brakes, but I'd start by swapping in a new set of pads on the Shimanos. Of course, you'll want to play with the toe in (which is generally the problem with the MAFAC design - y'gotta bend 'em to toe 'em). Then, I'd take a look at the rims - new rims or older, worn rims can be problematic. A new super-smooth rim can be a real squeaker. I've had friends use a scotch-brite pad to give the rim a little "tooth" in that situation. Some older rims develop a wave or suface imperfection from years of riding. You might also see how much play the Shimanos have - check the torque on the attachment bolt. It also seems like the longer the extension of the pads (i.e. the narrower the rim relative to the fork blades) the more likely to get squeaks. - Jim -- Jim Edgar [email protected] Cyclofiend Bicycle Photo Galleries - http://www.cyclofiend.com Current Classics - Cross Bikes Singlespeed - Working Bikes Get your photos posted: http://www.cyclofiend.com/guidelines "Maybe a bike, once discarded, pines away year after year for the first hand that steered it, and as it grows old it dreams, in its bike way, of the young roads." -- Robert McCammon, "Boy's Life" --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
