I’ve sanded and cleaned my disks with alcohol.
Bedded them in hard twice on clean rotors (the stopped squealing when they got really hot)

They are properly aligned, front and rear make the same noise.

They squeal more than any other brake I’ve used, wet and dry.

Anyone had similar, are shimano’s organic std no nice tech pads just rubbish?

Contaminated from factory maybe?

Tempted to put some über bike race matrix in there which seemed ok In my old deore’s. Any other recommendations, assuming ice tech pads aren’t worth the ridiculous cost…

buy a another set of pads and try them. if they dont squeal then your current ones must be contaminated.
