I recently got my car brought back to near peak condition with some overdue repairs. (At least my mechanic did a quality job and actually FIXED my issues, for less money, unlike one 'mechanic shop' next to KFC Diego Martin) One thing I did learn is that my rear brake drums are in a mess. Again thanks to the other 'mechanic shop' I been running on bamboo used rear hubs, that have metal scrapes inside, which were supposed to be new for over a year. So I am considering the idea of converting my rear brake drums to calipers. I own a Y11 Wingroad with big headlights. What kind of cost is involved? What parts do I get? What are the benefits?
