Because they are. I have a 2000 Voyager, which did well for about 44,000 miles. Then I had to have the rotors and front brakes replace. I went 22,000 miles, and needed them again. Then I went only 6000 miles and needed them again. At that point I complained, and they said perhaps the calipers were sticking, and so I paid to have the calipers replaced, as well as the rotors and brakes again. My adult daughter, who had been out of the country while this was going on, returned at that time, and bought the car from me. She became the sole driver, and 2000 miles later, the brake pads needed to be replaced, and the rotors needed to be machined. They suggested it was our driving habits, but since each of us was the only driver of the car for one of these periods, I can prove that is not so. Today we had to take it back after only 1,300 miles, because it sounds like the rotors are shot again. I think Chrysler has a problem, and we as consumers need to make them aware of it.

for the 94 caravan brakes,you should try replacing the rubber hose.I know lots of people had same problem and this fixed it . the hoses block inside, fluid comes out but will not go back. good luck.
