I was washing my car the other day and noticed that my front passenger wheel was covered in a ridiculous amount of brake dust. I looked at the pads on both sides and it's almost like the passenger side is wearing out twice as quick.

The weird thing is, it drives straight, and it stops just as straight, there's also no damage on the rotor. Which leads me to believe it has nothing to do with the calipers locking up, or not compressing at all.

So what could be causing this?

I know you believe it isn't the caliper but I wouldn't rule it out. I would check the slide pins and make sure they aren't corroded and lubricated properly.

yea either slide pins or you have one of the pistons not retracting. I had to replace both calipers on mine when I bought it because they were dragging, when I pulled the calipers 1 piston was fine while the other was frozen and wouldn't push back in.

Might try opening the bleeder on that caliper and see if any pressure remains ,have seen quite a few brake hoses that look ok on the outside but have a restriction inside due to either rust on a clamp or a defective hose,acts rather like a line lock.

Okay so I took both of the front wheels off to take a look at the brakes. The side that was having the issue: The slider pins were working great, and still greased up good, however when I took the pads out they literally crumbled, bits and pieces were falling off everywhere. I think the pads were maybe bad? That seems like a good reason why there would be a lot more dust. But anyways, I regreased the pins and put it back together with new pads.
The side that wasn't having an issue: the slider pins were dry as a bone, and did not move as freely, but everything else look great. I regreased the pins and put it back together.

I'm just seeing some of these new posts now, but when I was doing this I did take a look at the brake lines, they all look good. The car is relatively rust free, which is kind of weird being here in New England

Well today I took apart the brake on the passenger side again to take a look. For some reason the pad is wearing uneven. The top of the pad (the curved portion) doesn't seem to be touching the rotor at all. But the rotor seems fine and straight, not warped at all.

I would imagine that if one of the pistons was not working correctly the the left or right side of the pad would be less worn, not the top?

try bleeding the brakes, the slide pins on the rear have a tendancy to rust and freeze up as well.
