So, a couple months ago I did a full brake job. Rotors, pads, new fluid, etc. Also, had coolant flush and fill. Right after that I noticed that I have lost about 3-4 mpg off my average. My driving style is the same and where and when I am driving is the same. Any thoughts about what may have caused this?

 

I almost didn't respond, one thing does not effect the other......

And for other members reading..... had he had brake drag he would have mention signs about it like smell of hot brakes, excessive braking noise, reduced braking perfromance.....to name a few...
