I changed the front pads (akebono euro) and rotors (original volvo) in the last 1,000-1,500 miles and had a squeal when I first take off and they are cold. As soon as it warms up the squeal is gone. The brakes work great. The pins are in great shape, lubed up good, and everything is torqued and thread-locked (where necessary). I put the brakes back together (for the time being) and the noise is gone and they work great.

The pads and rotors are wearing unevenly. The outer surface of the rotor is only wearing on the outer 60% and the outer pad is the same. The same uneven pad and rotor wear on the inside, except it's the inner of the pad and rotor.

Ready for this? Both front wheels have the same thing...

Do caliper brackets warp, and do both warp at the same time?
Do brake pads vary in production such that I have a "bad batch".
Is there any harm in just letting the wear-in and waiting to see what happens (because they work great)?

BTW the car has 419,000 miles.

When you removed the old pads, I assume that they were worn evenly. Now, the pads appear to be touching all of the time.
So, is the spring properly in place? I suspect this a mechanic error, not a mechanical error. And, NO, do not continue driving like this and do not blame the pads!

Keeping it running is better than buying new

I improperly positioned the spring; you were exactly right.
If the spring is in the wrong position it can deflect the caliper 'floating' on the pins. This throws everything out of alignment. It's lucky for me it was caught it early on.

Thank you Klaus. You're the greatest...

Is it possible that the bearings have excessive play and are allowing the rotors to cock at at an angle in relation to the calipers? Original hubs/bearings at 400,000 miles??

Current rides: 2005 Volvo S80 2.5T, 2003 Volvo V70 2.4NA, 1973 Volvo 1800ES (getting ever closer to road worthiness)

The hub and bearing is quiet on both sides and there is no play.

Yes, original hubs and bearings....
