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 Bill Gomez

The delivery was fast and the packaging was pretty good. If you make your own brakes then this is a tool that is definitely a must have and will make braking 10x easier. This is for your rear brakes that have a screw in piston. Not sure why I saw another review saying it works better than a clamp. You cannot use the clip on the rear brakes, only on the front brakes where the pistons are compressed. It turns the pistons back very well. It's only one size so it won't fit all pistons, and if you're a little on the brakes you can also invest in a piston rewind tool, which comes in a whole range of different sizes. It's not expensive there.
