Nissan Repair: brakes overheating on left front side, brake caliper, nissan quest

Question
i have 1999 nissan quest with 110,000 miles. my front left brakes heats up and get very hot. i had the pads,brake lines, rotor, caliper, rear wheel cylinder and master cylinder changed but i still get that burning smell from the sticking front brakes. thank you.  

Answer
When you apply the brakes does it pull to one side?
If yes, is the brake caliper positioned towards the front or rear of the rotor?
By figuring where the brake caliper is positioned, I can tell you which way the steering wheel pulls and what the most likely problem is.
