Spring broken!! so while its being repaired...
my oppinion is to keep running them untill they are bad ... assuming you have no messages popping up on your dash saying you need to replace the brakes, or any vibration when you brake.
front fenders you can go aftermarket or try to source some used OEM ones if you're looking to save a few bucks. Honestly, if you put on good ones now chances are you'll have to get rid of the car by the time they'll rust through again as the rest of the car will be rusted completely.
good luck.

I am assuming that by front " wings " you mean the brake rotors/ disks.. yes OEM is the way to go , and no the rust you see is surface rust and thats cast iron, that doesnt mean that they are rusted through.
