I have a set of Avid Elixir 5's, done about 70 miles and squeeked and squeeled from day one - no sign of it letting up, I thought it would have stopped by now. Any ideas how to shut them up?
keep hands off brakes.
HTH
This ain't going to help, but mine never did shut up. I bought XT's to replace em.
Are you using Avid Pads and Disks?
Are they bedded in (got hot by hard breaking?)
Avid pads and disks and had plenty of use to bed in, or so i thought!
Make sure the alignment's perfect, it's not neccesarily the cause but it's a cause. And Elixirs have the bloody stupid tri-align don't they, to give them an extra axis to be wrong in?
Use sand paper to roughen both sides of the rotors. Hell, I'd even do the same with the pads - if that doesn't clear it up dunno what will
I had this on my Elixir5s. The following worked for me:-
1. Remove pads and roughen up with a file - mine were scored.
2. Wipe discs with brake cleaner or alcohol. (If they are quite scored, I've seen people recommend sanding them with a flat sanding block - I've never tried it.)
3. Re-align caliper. I don't know if I do it right but slacken bolts, pump lever a few times, hold lever down then tighten bolts.
I'd venture you have cleansweep3 rotors? The new HS1 rotors from Avid are meant to be much better behaved (and sized to industry norms 140,160,180,200 etc.) First ride this morning on my new 180mm HS1 seems to suggest the claims are true wrt squeeling etc. If you want to try it, they're on special at the mo on CRC.
My old xt brakes squealed and the only way I got rid of it was to switch from sintered to resin pads. Tried heating pads, scoring them and putting copper grease behind the pads.
A spot of copper grease on the rear of the pad? I think that's why they put copper grease on the back of car pas isn't it? To keep brake squeal down....
Only sure way is to remove the rotors 😉
I rather like sounding like an angry goose as I descend technical trails?
i had this on my specialized. cleaning with a disc specific cleaner helped a bit. in the end though i heard that there can be a problem with avid brakes and fsr suspension and I bought the GS3 solid sweeep rotor (it has no cut outs on the braking surface) and that worked a treat
I had this recently (new xt's on new superstar rotors). Squealed like pig for ages despite I believe, bedding in ok. Then finally after a long decent about a month later it all went away. Can now ride without mass squeal embarrassment!
