I've been riding on the same binders now for over 20,000 miles and was thinking it's about time for a new set of brakes. However, I don't know what kind of brakes are on my bike nor which ones I should go with. I want better than OEM brakes since I am putting stainless lines on it. What are sintered brakes and how do I know if they came on my bike. My owners manuel was lost several thousand miles ago. Thanks for any help.
