One of my rotors gets reallly really really hot?

my rear right side rotor gets really searing hot. recently, my brake pads wore to the metal and scored my rotor. I replaced both rotors and brake pads but after one day of use, the rotors look like they were burned and when I spray water on it, it sears~. I sprayed water on the other 3 rotors too and they aren't as bad as the right rear one. I dont hear any weird noises while driving so I dont think the caliper is sticking... hopefully... please help
