i just got my first fixie, its a cayne uno and the only way my parents will let me ride it (i'm a junior in high school) is if i get a front brake installed. so my question is this: does it matter if it's there as long as i'm still using my feet to slow down and i don't use the break?

(i don't give a rat's ass about the indie cool factor, all i care about is getting the best workout possible)
