can anyone help on how to take the rear rotors off... having issues with it and abouts to snow....

 

They should just slide off. Spray the center of the rotor with penetrating oil and then hit the center of the totor(between lug studs) and it should jar it loose. If the rotors have a rust ridge on the inside emergency brake drum you will have to crawl under the truck to release the adjusting wheel on the emergency brake shoes.
