How to replace rotors on a 2001 winstar

its got 80,000 miles on it. V6 3.8 question I have is .. I have a friend who wants me to replace the rotors, I have done it on many cars, but never a windstar, can you tell me if after I remove the caliper, does the rotor just slide off like most cars or do I need any special tools to remove it and how?
thanks
