Brake dust and Overheating brakes

I just replaced the pads and rotors a couple of months ago. I'm experiencing alot of brake dust and over heating,only on the driver side. I checked them out and the driverside pads are worn down more than the passenger side. I painted my calipers red on all four and the driver side is the only one discoloured from over heating I guess. Any ideas what the problem is?

Frozen caliper slider pins.

Unscrew the pins from the caliper (mounting bolts) and I'll bet they're a PITA to remove. Sand down the rust, regrease with hightemp stuff, clean out the holes with brake cleaner and pipe cleaners, and you're good to go.
