When it’s wet, or dirty ie during a cross race then every pair I’ve had have done it. Rival hydro, Shimano rs505, hope v-twin. All

Yep. 105s also rub when real gritty outside. I wonder if it’s the rotors, calipers or pads that gunk up and create rub? Could pad or rotor choice matter?

My sram and shimano road hydros are both okay. Other than a quick set up I’ve not touched them. Sram are on QR and shimano on axle.

I’ve got shimani, they don’t rub. My brother has SRAM force and they wail like a waily thing
