Review on Ultimate Brake Caliper Piston Rewind Tool: Wind Back with Right Handed Thread for Easy Replacement of Disc Brake Pads on Most Cars by Aaron Wood

Required for my two piston calipers on my Polaris. I really had to figure out how to make it work for me since it's made for a slightly wider caliper. Since it uses a standard 3/8" adapter, I just found a 3/8" drive head that fits my pistons and off I went racing. Easy to use and the screw runs smoothly. Great tool that I'm sure to add to my box.
