Iron rotors will rust and a treatment that inhibits rust on the braking surface will deminish brake performance.
Some brake pads squeel but many good ones do not. Also incorrect installation of pads and or failing to resurface rotors account for 90% of squeeling problems.
Chemical band aids are not the answer.
Fix the brakes.
