It's interesting to see cheques are still used in the 'States. Almost no one uses them here, even bank cheques are rare. No one trusts any cheques now.
All our bill payments and large payments are done by card or direct credit (online banking).
But, we clear card debt every month without fail...
Have a look at the rotors, see if there's a spot in the friction surface that looks different to the rest.
I'm picking that there's a patch of rust that gets scrubbed away on hard braking, but returns when the car's sitting.

We can't pay in large sums of cash either. It has to be reported to Police if it's over a certain amount. Too much money laundering and drug money around.
I'd treat the rust and paint it. I very much doubt a coating or two of paint will cause an imbalance in rotational forces on such a small radius. If it did, just strip the paint off.
Funny you should mention that. Back in the days before helmet mounted bike intercoms we had to use handheld mics at way more than 110 kmh steering one handed when on a job or in a chase.
