The saga of the squealing brake

How does everyone quell a squealing front brake? I've tried every remedy, filing the pad, toeing the pad, you name it, but the only solution I've found thus far is toeing out the pads the opposite way.

Anyone else run into this solution?

(Keep in mind, it did more the squeal when setup what would be considered the "proper way"; produced so much front brake shudder that the wheel would skip)

I hate to be 'that guy' but this has been done to death in tens or possibly hundreds of threads on here. A search for 'squeal' or 'shudder' is very informative, I promise.

"incorrect"

I think I've managed to improve the situation by running an unorthodox front pad setup, though I'm still going to try switching to a softer compound pad.

Are your pads completely perpendicular to the pads? I had a lot of squealing on my Avid Shorty 4's. I found out that the studs on my Cannondale X800 was .5mm longer. I went through my washer bin and place an extra washer on them. Then I made sure the pads was 90 degree against the rim with zero toe in and no squeal now.

Are you sure? This would mean that only the trailing edge of the pad would contact the rim.

One of my bikes requires that on the front also.

Toe, clean the pads, clean the braking surface. Still making noise... change the pads.
Reverse toeing is a bad thing.

I've gone to an Avid Rim Wrangler 2 setup with Swiss Stop RX Yellow pads.

Prior to this I actually fine-tuned the brakes with my training wheels (alum), but couldn't for the life of me get any sort of consistent behavior with my carbon race wheels.

'Cross bikes are much more sensitive to small changes than road bikes.

I spent probably an hour or two working on it with a regular toe and the pads are sill in good shape and rims and pad were clean at the time. I finally gave up and went to the bike shop to see if they could figure it out. Mechanic works on it for a good fifteen minutes no luck another mechanic happens to walk up and suggest a reverse toe worked on the first try. Been using that method and it works great every time on that patciular bike(Soma w/ house fork & avid 6). I use a thin card around 65lb cover to help set the toe. My other cross bike likes the toe the normal way (alum/carbon).

What's bad about it? It seems to be holding up just fine.
