Quieted MTB disc brakes

Postby am50em » Sun Sep 10, 2017 4:39 pm

After years of putting up with squealing SRAM/Avid Elixir CR brakes (once they got hot or wet) on my Anthem 29er I decided it was time to do something about them.

Purchased

Finally received all components and installed. Bedded in on short road ride then went off road and no more squealing (at least in the dry).
Rotors look good and performance is excellent. :D

They look really good. Let us know how they perform once you've bedded them in.

Some Avid/SRAM rotor models are notoriosly noisy. Putting anything else in would be an improvement!
I had a thought, but it got run over as it crossed my mind.

And new pads & rotors will pretty much always be quieter.
If you miss the noise, bleed them, but forget to take the pads out. :twisted:

My Avids were always noisy and as Duck said they were notorious for it. Maybe the modern ones are better but if I had direct replacements (from 2011) I am sure they would still be noisy.
Given good experience with Shimano Ice Tech and SwissStop metallic pads on my Revolt, they were an option but liked the look of the Uberbikes as they matched the original color scheme.
The Ice Tech Freeza would also be nice but not available in 6 bolt.

I don't miss the noise at all and I am sure the residents that I pass in the early morning wont miss it either! :lol:

Rode to work today via bush down from Pennant Hills Park, brakes completely silent down Concrete Hill.
Excellent!

i have 4 sets of elixers, rarely have issues with squealing,
rarely clean the rotors, as that is what creates the friction and keeps the brakes quiet,
rarely screw with pads, unless i'm bleeding the brake,
and just recently, lubed the pistons, by pushing out the pistons, minus the pads and lubing with Silicon grease, with a cotton bud
using original or aftermarket pads and the standard avid discs

This, I love the feel of my Elixir CRs but wouldn't say no to a little less noise and xfingers more power

Not a consideration for you now, but of interest to others, Ice Tech rotors do not fit with Avid calipers. Avid calipers are deeper than the Shimano models designed for use with the rotors, and foul on the tips of the long spider arms.

Good to know. Thanks.

i have a pair of XX world cups, they are organic pads only, as they magnesium, i forget what year
XO calipers i got on my santa cruz blur,
and 2 pairs of CR's on my commuter and 1 a set of spares,
various years and discs from roundagon to 185/ 180/160
in different years/disc model.
just need a bit of tweaking and TLC, and they run well
you do need to run the convex/concave washers that comes with the brakes, and are part of the system to make it work

@jackthelad
Interesting. I have never had any problem with my CRs apart from the squealing when hot or wet.
They have an excellent feel and easy one finger operation.
The CPS washers were/are installed and calipers were/are correctly mounted. Brakes were bedded in.

@duck
Thanks - I have read that the Ice Tech may fit but might require some filing of caliper (non-essential part!).
Google search will bring up other peoples experience. YMMV!
