This has made my brake job a lot easier. I have aftermarket 4-piston calipers and using two calipers and two steel plates was impractical. This tool fits in and does what it's supposed to. If you have well painted calipers, another pair of hands or a towel clean of debris will help keep the caliper from hitting anything as it takes some effort to start squeezing the pistons. The tool requires some strength/resistance to roll again for the next use. All in all, a valuable addition to your toolbox if you do a lot of braking work, especially as more and more powerful cars come with 4-6 piston calipers from the factory.
