I didn't get my fork until late September - drop shipped directly from WoundUp. So I am going to assume that I did in fact get a redesigned fork.
What is odd is that when you look at the pads and caliper - they are perfectly centered over the disc. The disc isn't bent or out of round. I'll mess with it a bit this weekend.
It does sound like it may be a different issue. The bike shop I was working with for the CoMo build was not close to El Paso, so I did not actually see the problem. Now that I think more about it, I think there was a mechanical interference between the rotor and caliper (i.e. the rotor was not lined up with the slot in the caliper). The work around was to mill the aluminum block to correct the alignment issue. It is working fine with the mod.
Did you set up the brakes per the Avid installation instructions?
ALIGN THE CALI PER
A. Turn the inboard (closest to the wheel) knob clockwise until it pushes the rotor
into the position shown. Note that the rotor should not be centered between
the walls of the caliper body.
B. Turn the outboard pad adjustment knob in until it is firmly squeezing the rotor against
the inboard pad – thus immobilizing the actuating arm. Your caliper is now in perfect
position and ready to be tightened. You’ll back the pads off again in a few moments.
C. Tighten the two CPS bolts that attach the caliper to the mounting bracket. Tighten
one and then the other, repeating until they are at the specified torque.
ADJUST THE PADS
Turn both pad adjustment knobs counterclockwise until desired pad/rotor clearance
is achieved (approx. 2 or 3 clicks each). important: only use the barrel
adjuster at the brake lever to adjust for cable slack. for lever throw, use the
outboard adjustment knob. for brake pad wear adjustment, use both the inboard and
outboard knobs.
I have obtained excellent (and quiet) brake performance when I use this method of adjustment.
Good luck!!
