Front drivers side caliper sticking-excessive brake dust.
Just as the above mentioned in the title. I drive 97% highway and I get alot of brake dust on that wheel. All the others are fine. I even hear the pads rubbing sometime. Is there anything that can be lubricated to unstick them? They aren't rubbing to point where my pads are worn all the way down but I'm getting excessive brake dust which is not good. I know on Medium duty diesel trucks you can lubricate the caliper pins but I haven't taken the calipers off the bmw yet to see whats going on. Anyone have the same experience and what did you do to solve it? I've seen used calipers on ebay for $50 bucks. TIA.

yes you just lubricate the caliper pins. It may not be stuck, it may just be the roads you are driving on that cause you to brake more while turning alowing more dust to collect on that wheel. If it is dragging you should be able to feel excess heat in the wheel on that side.

What Northern NY said..... While you are in there just inspect the caliper and make sure everything is the way it should be. I would def check them all to make sure they are all well lubed for proper function.

 This car has been widely praised in all aspects; many say it is the best BMW in the world. Consumer Reports gave the 2001 530i its highest car rating ever. The diesel engines available in the European models provide great torque and smoothness with better economy. The M5 has been called "the ultimate in discreet speed" with 369 lb·ft (500 N·m) of torque and a 0–60 mph time of 5.2 s. The only downside was its smallish cabin and trunk space of 11.1 ft³ (314 L) The very first E39 BMW 5 Series rolled off the assembly line on June 18, 1996. http://www.myspace.com/muaddibproductions

That sounds more like a sticking caliper than binding guide pins. A rebuilt (or replacement) of the front calipers is indicated.

Check your caliper boots. If they allow moisture in, they may be dry and sticking. Check those and if they are intact, pull them away and look at the caliper. Sometimes you don't have to buy new calipers if you take the time to clean and lube them.
