Old School Style - Brake Squeal, Fork Stutter Solved!!!!(10 posts)

Old School Style - Brake Squeal, Fork Stutter Solved!!!!atpjunkie
Nov 18, 2003 8:46 PM
I posted this below but I thought I'd share with everyone. For those of you who know, I broke a frame this year and yes, Specialized warrantied quickly and without no problem. KUDOS!!!! I'll post pix ASAP. Anyhow when building up my new S-Works I finally threw on the set of tubies (Ultegra Hub, Rigida SH-330 Rims, Tufo T-34 tires) I'd built up and got horrid brake squeal. Was so bad in front it caused enough fork shudder to shake the headset loose. I knew brakes were set right due to they hadn't changed from my old rig. I assumed it was the pad / rim interface as the 90's era Rigidas (semi aero 20 bucks a pair on ebay!) don't have a machined surface and are just anodized grey. I threw on my old clincher rims and there was no squeal at all. I was preparing to do the "acetone and steel wool" to the braking surface when I asked a friend who sells cx parts. He hooked me up with these wacky brake pads that he was using that he said he bought because they had a squeal free guarantee. So anyhow the brake pads are called YEHSTAR Gigapower Ceramic, there's logo and name on them LGA (Landesgewerbeanstalt Bayern) my guess is German or Dutch. They are post type canti pads (Spooky, PAUL, Froglegg etc..) and guess what? THEY FREAKIN' WORK! put them on, no tweaking, no rim prep, just set them on and BINGO squeal free. Brakes actually have built in toe-in as well. Could not have been easier. I'll post a pic of the box ASAP. They appear to be mfred at the technical university of Aachen (my Germanic Translation). My pal says they wear pretty quick but who cares, they work.

Found the link:

It appears that they are made in China but maybe some company in Germany developed the prototype. Looks like they are using aluminum oxide in the rubber for better grip and wear.

they're actually using a ceramic compound, if the link you provided serves. It says other mfg's use alu. Spsh...details...

Cheers!

The Yehstars are what Avid sent me the first time I called about squeal on my Shorty Ti's several years ago... They did work better then some of the other brands I tried but I was eventually out of luck once they wore out...

The Yehstars I tried where slightly different. They were threaded vs. the post mount style I don't remember anything about "Gigapower Ceramic". I do remember that the did work pretty well though...

Hmmm... Better start googling Yehstar!
do they stop as well?damon

Cool, glad to hear! My mysterious squealing problem mysteriously went away after a single soggy (road) ride. Today, the same setup was quiet as a mouse.

I should probably get a set of your yehstars, just in case, though.... Question - are they as powerful as your old brake pads (or better yet, the best pads in the world, kool stop salmons)?

Thanks for the report,

yes they stop very well. they feel very soft, braking feels almost gooey vs. rubby. (does this analogy help?) here's what they look like.
