I've recently bought a lovely new bike,a Transition Spur. The bike is fantastic but it came with the Maguras but matched with TRP rotors but suffered from really bad brake noise-the classic avid brake turkey gobbler sound under braking. I thought that maybe there was a mismatch in resonance here between caliper and rotor so thought buying new Magura Storm rotors to have a 'matched system' would solve it-it hasn't ,if anything it's worse. Anyone have any experience with these brakes-that could offer me a solution.....Cheers.
Second hand? The rotors might just need a good cleaning + pads sanding and cleaning too, but I'm presuming you've tried that already.
Technically second hand,but barely ridden. Like I say brand new rotors now and bedded in properly but hopefully I wouldn't need to sand down all pads - there 8 of them in total.
I'm wondering if it's the pad contact area-pads seem to brake lower on the splines of rotor /gapped bit .
I had this and by pure fluke cured it. fitting galfer std black organic pads cured it
You say fluke, it's not an issue they're known for so quite possibly it's dodgy pads with the material a bit low.
<p style="text-align: left;">Could well be .I was advised the pads that came with them new were galfer but they were like this from new . swapped pads all sorted</p>
Friend had this with a brand new set, with magura rotors, along with constantly try to keep them from stopping rubbing, he could never cure it. I believe this contributed to him selling them.
I would add, they were the most powerful brake I'd used, very powerful but the noise meant you tried to avoid using them...
yes, I had exactly the same noise with my MT7 brakes when I was using uberbike race matrix pads, I switched to the official magura pads and the noise was gone.
The noise was horrendous - Istarted a thread about it on here , will find it in a sec
edit : heres my thread - I'd put money on it being your brake pads, try some official magura pads

What I did when I bought a bike with Magura brakes was remove them on day 1. List them on FB Marketplace as "literally brand new, never even ridden" and then put the £150 towards some Hope Tech 4's.
Now my brakes work great.
Brake mounts faced and both flat? Rotor hitting pads properly - square and evenly?

That's not an unusual comment mind.
As above, try different pads.
Hope Tech 4’s.

The tech3 e4 I had were the most disappointing brakes I ever owned. Each to their own I guess.
Thanks for the suggestions folks,turns out the bike shop had by default swapped out the original brake pads for Galfa ones that they consider superior......they are a different design to originals being individual pads rather than connected ones and also being bolt in rather than free floating . Anyway just had a quick bedding in ride and the Spur and brakes are now quiet.....as it should of been-hopefully it continues..... .

Where are those washers from...
Official Magura pads can be linked (i.e. 1 pad per side) or separate (2 pads per side). The linked pads are normally the lower spec oem item. E.g. https://magura.com/en/EUR/product/brake-pads-sport/more . If you look at the 2nd and 3rd pictures both the separate and linked version are available. If you look at the higher spec pads (race version) there is no linked version available. The linked version does not require a retention pin which is a cost down on the cheaper brake models. The retention pin is an upgrade as it makes pad swapping easier and they are more secure.
Now my brakes work great.
I have both MT trail sports and Tech4 E4. One of those sets made a noise like the OP describes and it wasn't the magura's. Both also work great (though I have removed the stock E4 green pad and fitted reds which are quieter).
Those washers were my plan B/fault finding -just in case all the noise was caused by the pads running too low on the rotors.....plan A seems to have worked though (fingers crossed).
