05Chevy

If yall could link me to some brakes that i would need that would be helpful

Im thinking about getting rid of my old factory wheels and getting either 22's or 24's on a dark gray 05 Chevy silverado 1500 ext cab. There black rim with a chrome lip. My brother was telling me if you put 22's or 24's on you will have to get a whole new brake system to support them. is that true. I found some 24's that are on sale for 199.99 each. But i work at a Discount tire and i dont know if they will give me the same price or carry them and my discount is only like between 15-20% should i just buy the rims from the ppl on line.
