Ok, I've run into a wall.

I didn't make the connection at first, but my new wheel is causing my Avid BB7 front disc brake to squeal like mad. It's been a long process to figure it out. This is what I have tried to eliminate brake squeal:

-Organic pads
-New rotor (Shimano XT instead of Avid 160mm)
-New comprensionless housing and cables (Avid Flack Jacket)

Then I decided to dig out my old front wheel and mount the original Avid rotor: no squeal. Must be the new wheel then!!!

The bike is a 2008 Salsa El Mariachi with the original rigid steel fork.
Old front wheel is an XT hub/ Salsa Semi.
New wheel is a WTB front hub/ Stans rim.

It squeals in dry and wet conditions. It does so only when braking softly to medium strength. When braking hard, the squealing dissapears.
It is like the squealing is resonating through the wheel and fork and transfering vibration to the handlebars.
There is no noticeable play on the front hub.

Do you guys/gals have any suggestions on how to go about getting rid off the squeal?
Retension the wheel maybe?


I really don't know where to go from here and I would like to use keep using the new wheel...
