Ok, so Ive established that it wouldnt be a bad idea to upgrade my brakes with bigger ones because of the size of my tires. So which ones do I go with? What all do I need? And the most important part, what kind of price tag am I looking at? I dont want to get too fancy, but I do want to upgrade.
Thanks for any advice.

p.s. I will be taking this to a shop because I am mechanically challenged.
