Severe brake squeal/chatter: Tektro Onyx brakes w/ Kool-Stop Salmon pads
Dear group,
I'm having trouble with brake noise. The brakes in question are Tektro Onyx. Originally, on the factory pads, I had no brake noise whatsoever. I changed to Kool-Stop Salmon pads (with off-center stud), which squealed horribly and displayed chatter on hard braking as well. Wear didn't seem to make any change. After a few hundred miles, I added toe-in; rather severe toe-in was required to quiet them (though they still gave slight noise just as rotation ceased). Now, however, 600-800 miles later, the noise is back with a vengance. The brakes are pretty loose; the arms have significant wiggle. Is this likely to be the problem? Would better brakes improve the situation? What about switching to sidepull caliper brakes? Thanks for any help, Reid |

They work fine on the front. I was using sram 7.0 v-brake style. ANY pressure caused screaming from the rear brake. I tried toe in to the extend that the brake were very mushy. Cleaning the pads didn't help, a booster didn't help, sanding rims didn't help. I even filed down one of the bosses to get rid of brake arm wiggle. What helped was switching the pads to ones made by trace / lambert. The number of the package is 21-1526-0 Also they are the replaceable cartridge type. The complete saga can be read at google "rear brake screaming on tailwind" on the recumbent group. |

I swapped out the original Shimano pads after 1600+ miles, mostly because I wasn't entirely happy with their stopping power (which in hilly Seattle is important), and read online that the KS's were supposedly leagues better. Well, they do brake better, but not THAT much better, and in any case the squeal is simply not worth it. I fully expect local dogs to come running after me and windows to break if this keeps up, if my eardrums don't burst first. I think I'm going to go back to Shimano pads. I read somewhere that they've come out with a new rubber compound that's supposed to improve braking power. Sorry I can't help you with your brake problem, but if they're loose then that's not a good sign. Have you had them checked by a LBS? What kinds of brakes are they? I don't know anything about this brand but if they're low-end you might want to think about upgrading to better ones. Check out the online shops or www.roadbikereview.com. Good luck, and keep those earplugs on! -- Kovie zen |

I've been more satisfied, noise wise at least, with the cheapest KS pads. The all black version for cantis and linear pull, and the hard to find but wonderful cheap grey Continentals for my old Shimano 600 side pulls. |
