01 C320 Brake Pad question

Hi All,

Good day. I own a 01 C320. And recently its time for me to change the brake pads. Does anyone know who makes brake pads for this car? The dealer wantst o charge me over 500 to change the brake pads which I think is too much. Hope to get it done outside for less. but I like to have the same quality pads as the original. Any advise? Much appreciated
