I bought a BRAND NEW Grimeca 203mm rotor, and when I spaced out my caliper and set-up my brakes, I noticed it only rubs on one portion of the rotor, like it's warped.

I spin the wheel and can't SEE any wobble, but you can hear it rub the pads "shing shing shing". I only have 1 UBER PAPER THIN shim on the bolts, if I put one more shim, the entire pad contacts the rotor, and if I put no shims, the OTHER pad contacts the rotor....

The brakes are new, Magura Louise. I rode around with with no shims to break in the pads and they rubbed, but with ANY shims it would rub pretty badly.....so I finally shimmed it and now it doesn't rub AT ALL except at one spot "shing shing shing" when I spin the wheel.....

Is it the pads breaking in and setting, or is my rotor warped REALLY slightly? I mean, one super thin shim, I don't think I could see a warp that minute, LOL.

Try riding it like that for awhile... it might stop once the pad wears down a bit.
I always found it way too tedious to get my pads to stop rubbing when it was a tiny rub like yours... so I just rode it. It went away eventually :|

Yeah...it sucks.... My clearances are so minute that if I lean the bike far while riding to one side, it rubs...LOL....nothing that slows you...you just hear it....

Damn, when I had Hopes, everybody complained about shitty brake noises. I never had that problem, but these Maguras are funny...and DEFINITLY nice as nice feeling, LOL.

Bah!...the Hope DH4 CALIPER weighs as much as my Magura Louise system, LOL!

just ride it, not a big deal. as long as its not bad rotor drag

you could file your caliper mount a little bit, to remove a minute amount of paint/material if you really wanted.

:fix: yeah, I was thinkin of that, so I could utilize more spacers...but eh...it's fine where it is.....

give the pads a bit to wear in, if the sound continues after a few rides, then consider sanding the brake mounts....
