Bet the brake pads are paper thin and the caliper pistons are out too far. That leads to brake fluid leaking and loss of brakes. Going to have a mechanic fix it or just drive until you blow through a red light?
Brake fluid is leaking onto the rotors. Get them serviced asap.
Car, Truck, Bike, Boat, Horse and Buggy???
Generically speaking, my GUESS would be a seized caliper (or 2,3,4) coupled with a brake fluid leak.
Is the Brake Fluid low?
Its normal for rotors to accumulate some surface rust after sitting a while. A hard brake pedal can be caused by a malfunctioning brake booster
My front brake rotors are covered in rusty looking oil or fluid; the brake pedal requires a lot of pressure to slow the vehicle down.
