It's strange that the affect is only on the rear brake. I'm thinking it might be because the caliber gets covered in snow more easily than the the front.
I'm surprised no one came up with a 3D printed caliper cover for fatbike. When you dive in snow with hot discs and pads it ices instantly. You end up with no brakes usually at the most inappropriate time.
Never really a problem. Crossing streams with supercooled water, yeah you can get some ice, riding dragging the brake burns it off easy.I'm surprised no one came up with a 3D printed caliper cover for fatbike.

Switch to Hayes?
Grease the pads.
1.8 mm two piece TRPs have worked the best for me. Start out the straightest, stay the straightest. Unfortunately the 2.3mm disks will not work with Dominions.
Are you talking about the TRP slotted rotors (TR33)?
Yes. I have tried Shimano, Hayes, SRAM and TRP rotors. The TR33s seem to be the straightest, although that isn't based on a large sample size. I actually mount a dial indicator to the fork axle to measure and align the rotors. I have found you need less than 0.005" TIR to even have a chance with Dominions, and 0.005" is hard to achieve with thin bits of sheet metal that go through heavy thermal cycles.
Interesting, I'll take a look. Sounds like you haven't checked/tried Galfer Waves or Sharks?
The price of those things tho....
I tried one of those, it will go in if you push the pads out, but only gets you in the ballpark.I actually picked up one of those old school caliper aligning tool things (think folded over piece of paper thin metal) and there's no chance of sliding it in between the pads and rotors.
Add Formula 2-piece to the party. Unfortunately out of production, I'm on the hunt permanently to no real success.

I also liked those rotors. I still have some but they are very thin and cupped.
Mine are starting to really show some wear as well. I don't really understand why they have been discontinued, awesome product imho. @Udi also loved them.
curious how you find them, mine both make lots of vibrations/squeaking mit m8120 and shimano sintered pads
Keep an eye out for deals on the Trickstuff rotors. They seem nice to me, just too thick I think for these Hayes (or this particular set). No idea where they fall on the Westy straightness scale, but I got them for something like $25. They were super cheap.
Yeah, that was my hesitation with the TS ones... 2.05mm. There's already soooo little clearance for the Hayes with a 2.0 that I didn't want to chance it.
Will do. If there's one thing I'm good at, it's complaining about bike noises. One set will go on the ebike with metallic pads, the other set on the enduro bike with organic pads. I also downsized the front rotor on the ebike from 220 to 203 with these... at one point I was running 220f/r on it and getting tons of noise with the metallics, but once I downsized to 220f/200r it got better. I suspect that some of my brake noise on that bike is due to it taking longer to heat up the rotor/pads due to the big rotor.
Bored here at work so I fired up the good ole MTBR and got linked to this beauty:
Weak legs
Consider facing your brake mounts, from my experience, this solves 90% of cases.
Are the HS2s that bad? I was gonna try them next. I've got my Hayes on Shimano RT86 on one bike and Hope floating on the other. I prefer the Hopes but its a no-go as the insertion tab on the Dominion pads hits the rivets just as the pads are about worn out.
Yeah mine do that at the bottom of steep runs. I don't mind that, but the rivet thingy that holds the rotor to the spider hits the insertion tabs on the Hayes pads when the pads wear down and thats not great.
