WD40 to the brake disc and pads

Here I'm with a stupid question again. I sprayed WD40 to my rear brake disc and pads thinking it's brake pad spray early in the morning. I drove a bit and stopped at the first gas station to buy brake pad spray and sprayed a lot to fix it (it normally cleans grease, dust and similar) but somehow it doesn't fix WD40. I literally greased my own brakes now I'm driving only with front brakes. What should I use?
