I notice the rotor in not worn on 30% of the brake surface. I just bought the car and that looks suspect to me.
Anyone else see something not right?
The second picture is the rear, it looks ok.

thanks

It does look odd. How many pistons are in the calipers?

I wonder if the car had larger brakes on the front at some point and the previous owner replaced the rotors with std Mustang items for whatever reason? I'd pull the calipers with the expectation of finding the brake pads with a definitive step in them... some surface used and some untouched. If so, you may need to source the larger (Cobra, I think) rotors. My two cents.

Normal. That's how Cobra brakes are.

The caliper used on the 94-04 Cobra brakes was originally designed for 12" rotors and later adapted for 13" rotors on the Vette and Mustang. As a result, the pads don't sweep on a larger portion of the rotor. This is how they are, everything in your pic looks correct for Front and Rear 94-04 Cobra brakes.

On your setup, it stands out dramatically due to the large rust area. With different rotors, it's not as obvious
