how do i fix brake fade in a 1953 compact car?

[eyebrow raise gaming]

both of my brakes are at max size (10 inches on both front and rear) i don't understand what's going on

1953 is going on. Brake fade was a thing until to the 70es, so it is pretty normal for a 50es car with 50es wheel dimensions to suffer from brake fade probably even at yellow level.

For additional context my 1988 Ford Thunderbird Turbo Coupe was one of earliest American cars with 4-wheel anti-lock disc brakes... and it faded when worked hard. Expecting fade-free brakes in a 1953 car is an exercise in futility. All you can do is try to minimize it (larger wheel diameter, so you can fit even larger brakes and/or lots of brake cooling). Even the almighty Z32 Nissan 300ZX Turbo had brake fade and that was a sports car with 4-piston calipers on vented discs at the front, twin-piston calipers at the rear. https://www.caranddriver.com/reviews/comparison-test/a15140581/nissan-300zx-turbo-vs-dodge-stealth-r-t-turbo-archived-comparison-test/

Larger brakes with less weight, but as said above, limitations with technology means brake fade will always be a thing.

It's worth mentioning too that sportiness fade is not something you should be tremendously concerned about in anything but a track car, sports car or super/hypercar. It's an extremely demanding test that determines the fade in that situation.

Driveability brake fade, and to a lesser extent utility brake fade (for certain demographics) is the most important type of fade to be concerned with.

To add a bit more to this, sportiness brake fade measures repeated braking events from high speed in quick succession as expected on a racing track, which means the brakes stay hot through not having a chance to cool down between braking events.

Real world, normal day to day driving, it's very unlikely that you'll ever need to do two or
more emergency stops sufficiently close that this is an issue, and pretty much any braking system designed to handle normal road braking is going to suffer if used in a track environment; if a typical emergency stop scenario is 70mph to zero once, and you start demanding multiple 100+mph stops in quick succession from that same braking system, you are repeatedly putting more than twice the kinetic energy through the system than it was intended for. It's going to suffer...

Without loading the game up to check, a sportiness brake fade test is probably putting ten, maybe twenty times the energy into the brakes over a drivability brake fade test.
