Chrysler Repair: 2002 front brake problem, wheel disk brakes, chrysler town and country

Question
I HAVE A 2002 CHRYSLER TOWN AND COUNTRY VAN. IT HAS 4 WHEEL DISK BRAKES.IT IS GOING THROUGH FRONT BRAKES IN ABOUT 8,000 MILES,BOTH OF THE FRONT BRAKES PADS GET WORN DOWN ON BOTH SIDES AND I STARTED WITH REPLACEING THE FRONT CALIPERS AND IT DID NOT FIX PROBLEM? WHAT DO YOU THINK? THANKS BOB

Answer
A couple things to look at....Is there fluid pressure when the peddle is not pressed?Other words crack a bleeder,does it squirt?If so I would look at the master cylinder or the actuating rod in the booster.If the inboard and outboard pads are wearing evenly then its not a caliper.Does the vehicle lunge forward when you brake.That would mean the rears aren't working right.In which that could again be a master but also could be a proportioning valve
