2005 Kia Amanti, Rapidly falling MPG

I have a 2005 Kia Amanti, I have been averaging just over 23 MPG. Last week the overall MPG just started to fall 3 or 4 tenth a day, today I'm at 18.4 MPG and Falling. That's almost 25% less gas milage in a week! What could be causing this? I have not changed the way I drive or how much I drive, I'm very consistant, work and back, to the kids football practice and back, I use the cruse control everyday, set at 65. Most of my driving is highway.

The car has 80K on it.

Will be replacing brakes on 04 kia amanti soon.Any thing i should be aware of when changing them?

Yes be careful with the caliper pistons, make sure they do not fall out.
You must push them back into the cylinders in order to put new pads in.
Thats now out of the way, Just be sure to lube up the sliding pins on the calipers. if you are replacing rotors be careful of the brake lines when you remove the caliper and to hang the caliper with a wire hanger or caliper hanger if you have one to not stress the brake lines
