Excessive brake dust on front driver's rim
 
All rotors(upgraded to "heavy duty") and pads were recently changed out within the last 6K by my tech. Noticed within the last week that the driver's front wheel is "loaded" with brake dust compared to all of the other three rims. Is a 2002 GC 4.7 SE. New event. What should I look for and is this possibly normal? My gut tells me otherwise. Jeep is not driven with a lot of harsh stop and go. Ideas anybody as to begin to isolate the cause? Possibility of a "Non-disengaging caliper"? Thanks for any direction(s).

Get a caliper (measuring instrument: see pic) and check the difference between the front pads. Left vs right. Inside and outside pads.

If there is a notable difference you may need a new/rebuilt caliper.

Is it pulling to that side?

you will likely need to replace the caliper. when i had a WJ i had to replace my drivers side caliper at about 99k miles.

I would first check if the caliper sliding pins are greased. When they are dry, the caliper will not freely move and the pads will stay in contact with the rotor.

This is what I would start with. Also make sure that you measure the same section of the pads on each side. Brake pads do not wear evenly from front to back, there's more friction (thus more wear) on the leading edge than the trailing edge of the pad. They also don't wear evenly top to bottom, the outside of the rotor is moving faster (talking linear velocity) than the inside of the rotor (creating uneven wear).
