Mercedes c240 on 2003 Mercedes-Benz C240

My front breaks and rotors where bad it would mark on the dash i just replaced them but it steal marks on the dash what can the problem be or what can i do to take it off

Where the sensors damaged? Was the brake job done at a shop?
I dont know how to tell if there bad and i did the work my self at my shop
Were there wires attached to either inboard or outboard brake pads when you removed the old pads?
