front pads one is more worn away than the other

[eboy0]

I just noticed this today when i went to change my front pads... my passenger side is completely worn away, maybe 1mm left of surface, while my drivers side has a good 3mm left of surface... what could this be caused by?

Do the brake pads move in the clips? Are the slider bolts on both sides in good condition, not corroded? Are the sliders properly lubricated? Just a dab will do. Are both calipers in good working condition? Can you manually (by hand) press them in? What condition are your brake lines in? Were they properly bled? When was the last time you exchanged your brake fluid? = Drain refill and rebleed? In terms of weird brake happenings, three mm isn't that huge if they wore nice and clean even across the rotor. If one side is good and the other brake pad on the same caliper is gone to the rivets it might be a sign of stiction somewhere in the system. Is the rotor thinner on one side of the car than the other?

A bad wheel bearing on some cars will allow the wheel to tilt inward, causing rubbing from the pad, onto the rotor surface. I have had this happen.
Are there any grooves or marks on the rotor?

a wheel bearing going bad? You're looking for a slight drag on the brake system not an all out clamping.

Ok, what most likely your problem is, is that you have a worn or bad caliper and or piston, or it could be sticky or rusty from sitting around, which is causing your passenger side to wear out faster then your driverside, which in case when you hit the brake pedal, it should be an even 50/50 to each side, but in this case you might be only giving your driver side 20-30% of the pressure, if your car is drivable with the brakes in, go ahead and do a test.

Speed up to about 30-40mph, let go of the steering wheel (make sure you are in a safe parking lot of some sort) and hit the brakes pretty hard, but not enough to start skidding, and see if it pulls to the left or right, then you can determine that it is a sticky caliber or not.
