I really want some better brakes. Should I buy bigger brake pads? Can I install disk brakes on a Diamondback coil 04? I hear disc brakes are extremely fragile and delicate. Someone told me that if a twig gets stuck in disc brakes then the will bend, Is this true? Will discs fit on my diamondback? and if they do, what type of brakes do you guys recomend? If discs don't fit then what kind of calipers/pads should I get? Lets just say I have 200 dollars? Maybe 300.
