Jack up the car and spin the tires. Do they turn freely? If a caliper is hanging up the brakes will drag and kill your mileage.

alright. thanks danthurs. you might know this one too. everytime i press the brakes. they lose pressure and then i have to re pump the brakes. does that mean i need a new brake booster?
