GAS MILEAGE

2004 Jeep Liberty • 6 cylinder 4WD Automatic • 94,000 miles

I have a 2004 jeep liberty. I recently change the brakes and now my gas mileage is dropped from 250 to 175 a tank. I have also started warming my car up for 10 to 15 minutes before I take my daughter to day care as it in extremely cold in MN. I do not smell anything or hear anything coming from my brakes. Could I just see this much of a drop in mileage from warming up my car or should I look at my brakes. If my brakes what should I look for?

Check your brakes if its dragging due to sticking caliper piston-It always takes a lot of fuel usage during cold starts to fire the engine up-when the last time you have it tune-up

I had a tune up about a year ago. Would collapsing my caliper piston and re bleeding my breaks help?
