Drum brakes.
Your brakes are warn out or your plastick wheel cover is not on right
This problem is caused by disc brakes that have a fluid leaking from the calipers. You can buy loaded calipers an install to the car to fix the problem.
Warped front rotors are the most likely cause
no
Smoking brakes usually indicate a stuck caliper or improper install on pads/shoes. Have you calipers checked and make use they move smoothly.
Same as the Caravan...
It could be bad brakes or bad wheel bearing.
not unless you want to change the rotors and calipers and a bunch of other stuff
calipers
Nope, the same routine, right rear, left rear, right front, left front.
The front brakes on the Windstar are disc brakes. The rear brakes are drum type. You need to know exactly which parts need to be changed and why. If it is just the pads its pretty easy to do. But if the rotors are bad too, you will need to remove the calipers to access them then re-install the calipers with new pads. If you are not sure what you are doing seek advice from a mechanic
