Any suggestions for my ford?

I have already replaced the brakes, brake disc rotor and the Caliper. When i strp on the brakes there's a loud creaking noise but when i don't there's no noise. What should I do to stop the noise? I think it might have something to do with the brakes Thanks in advance

Opinions about a 2007 Ford Crown Vic?

Thinking about buying this 2006 crown vic.

I heard the air ride suspension is a headache to fix.

This seems like a good tough car, they use them for Taxi's don't they?

1999 Ford Windstar LX van with 120,000 miles on it, just blew a head gasket. What should I do?

I have taken the van to 3 different shops in my area and each place have said the same thing, " Blown Head Gasket", now I would like other peoples opinion on this. The quotes I have to fix this van will cost more than what the van is actually worth, so, should I fix the thing or try to save the money up to buy something else. The van has ran fine for the past four years, and just lately it has started to have issues… What do you think I should do? Any information is helpful.
