Persistent front wheel squealing: Replace the fork? Switch to disk?
I switched from an aluminum fork to carbon and the brakes howled like crazy. I went the usual route of cleaning, adjusting etc. What worked is counterintuitive, but I toed the shoes out. The noise went away immediately. I read somewhere that it can have something to do with the harmonics of the carbon fork.  So I have the rears toed in and the front toed out and there is no noise.
