I'm trying to find information in what it entails to change out my '05 Corolla drum brakes on the rear to disc brakes. I want to change out the whole assembly to a disc system. I've been searching for them in my area (Bay Area, CA), but its hard luck finding the whole setup. I was thinking about finding a ruined '05 Corolla XRS and get the rear disc assembly from that, but are there other options? Any info would be helpful! =D
