Sqealing Brakes - tried all the usual stuff
Riding a 2007 Tricross Comp with Avid Shorty 4 brakes.
Rear brake is fine - quiet.
Front squeals like a pig. Have put on some Kool Stop multi MTB pads (multi-compound), cleaned the wheel, sanded the rim slightly,cleaned again, toed in the pads. Still squeals like hell, and has a bit of a shudder now too -- I'm thinking maybe I toed them in too much? Would that cause the shudder/stutter?
Any other suggestions? Thanks.

You can always try a brake booster.
If the cause of your canti squeal is a slightly-too-flexy fork, then this could solve it.
The "shudder" part leads me to believe this could be it.

I doubt you toed them in too much. You may not have toed them in enough.

I think I'll give a brake booster a try. Any recommendations -- is any one better than another?
bmorey - I probably have about that much toe-in as well, and I thought it might be excessive. I played with different amounts, and nothing seemed to work too well. I put in what I thought was too much, and it worked for the first couple rides, then started squealing louder than ever.
Makes me want disc brakes.

Toeing in costs less than a brake booster. I'm telling you, it will work. Keep increasing the toe-in until the noise goes away.

Well, a brake booster costs about $6 (one for the front brake only). The pads can be left parallel to the rim - no toe in necessary. To me when the pads are parallel to the rim, the braking action feels more powerful compared to toed in pads. So if toed in pads feel squishy try a brake booster.

I had the same problem on my 'cross bike with carbon fork. Seemed that no matter what I tried the front brakes would squeal and shudder like crazy. Toeing the pads to an extreme is NOT recommended as you will find that you will lose alot of braking power. After trying many different pads I think I've finally found the answer ... Kool Stop Tectonic pads. These are very highly rated and after putting them on my bike with no toe-in there is no squealing and the brakes are rock solid. You can get the pads at Cambria Bike for less than $10/pr ... https://www.cambriabike.com/shopexd.a...RIM+BRKAE+PADS

Shorty's have been known to squeal like crazy and I couldn't ever get them to stop. You can switch out to something like the Tektro 720 for $25 (use you KS pads) and you will get excellent power and modulation with no squeal or shutter. I'm currently running these on my Cannondale CX9 with the EC90X carbon fork with great luck.

Humidity would mimic the effects of riding in the rain. Wet-rim squeal is a common phenomena. Perhaps a softer pad, or a harder one for this? I'd experiment.

Brake boosters -- is there another name for this item? I can't find them here in Australia. May be they'are called something else here. I'd like to try one on the front of my bike.

Makes sure the brake bushings aren't shot too. front/back play can cause the same problems. See if the brake arms seem loose?,,,BD

OK...i'm going to make a confession here, as embarassing as it might be -- had the brakes reversed toed!
Why?
Because I mis-interpreted the toe as being the part of the pad that would be pointing facing into the the spinning wheel. Momma always said....
So, toed slightly and correctly, using Kool Stops -- no squeal, good braking power.
Toe = front. DOH!

Don't feel bad. We all make mistakes like that, and you're especially excused if you're new to this stuff.
Yeah, healed-in brakes should squeak pretty well!

I just toed-in the pads on the Dia-Compe brakes that came on my old PUCH 3-spd. I used an adjustable-wrench on the arms. It's nice to get back to the basics once in a while...now where's my hammer....
