Car is 100% fucked.
Burn car, it's not worth fixing at all.
Should have bought a better car.
Joking aside, simple answer is your brakes cooked the grease to its melting point, thus flowing the path of lest resistance and just oozed out a bit.
If it makes you feel better buy new boots and re lube those pins.
