2001 Ford Taurus repairng break drums

Sorry to hear that
how can help you
also front has brake rotors and not drums

The antifreeze line(usually referred to as radiator hose) leak is usually a simple repair;first, identify the leaking line, this can usually be done with a visual inspection. Let me know if you want to do it yourself and I can walk you through it.
The front wheels have to be measured to find out if it needs replacement but use your best judgement, visit a tire site and lookup the penny test. Consider a tire rotaion if money is a problem right now. If you have a voltmeter you can test the condition of the alternator by measuring battery voltage with the car off and running. You should have about 2 volts (14volts total) of difference with the car running.
I doubt that you have front drum brakes. Rust is normal due to moisture in the air. It should start to dissapear as you drive the car more. What should concern you is the thickness of the rotors and brake pads, these too, have to be measured against manufacturers specs.
