How do I know if my brakes need replacement?
user
A sensor may fail causing the brake warning light to illuminate. If you suspect your car has a brake sensor problem, consult your mechanic for a diagnosis and proper course of action.

any other way i could tell?
user
In the absence of any warning lights illuminating, there is no reliable method of braking-system diagnosis. A physical inspection of the vehicle is often required to ascertain the cause of a failing warning light.

how often should i change my brakes?
user
Brakes wear out gradually, and require periodic inspections and periodic replacement to maintain safe driving performance.
assistant
so you don't know any signs i should look out for?
user
A normal brake pedal gives you a “feel” that a warning light (and/or the need for replacement) should not have.  I can tell you what the warning lights and their function are, but I cannot tell you if you should be concerned about your brakes.  For that, you need to get a visual inspection from a mechanic.
