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 Brian Hazzard

I am fortunate to have my brakes overhauled every few years and a tool like this is required for rear calipers on most cars. The adapter is double-sided with contacts arranged differently on each side. This is a cheap and simple device that works great. If you don't use it every day I wouldn't pay more for something better. It's just wonderful!
