I searched through the forums and think that I can replace my front pads. I've replaced pads many times on Chevy, Ford, and Chrysler vehicles. From what I have read, I should disconnect the 12 volt battery before I begin work. I have a Craftsman brand manual caliper piston compressing tool and many other hand tools, jacks, jack stands, etc. For my other vehicles, I have the specific bits needed to loosen the caliper slide bolts. What size bit/socket is needed to loosen the caliper slide bolts on the Prius? Do the rotors simply pop off after removing the calipers? I'll be doing the work outside in the cold weather so I'd like to have all of the required tools to complete the job quickly.
