A rear disc upgrade is a lot of work and a good chunk of change even with junkyard parts for very little (if any) reward in a small and light car like the Yaris. Not to mention the lower maintenance, parts costs and much longer lifespan of rear drums over discs.

Proper way to adjust the rear drums is to keep increasing tension untill the wheel begins to drag when you try to spin it with the drum on and the parking brake off.
