After reading some negative reviews about this product, I was a bit reluctant to buy it. What bothered me the most was that some people wrote that the caliper had uneven jaw alignment and ruined the brake lines or just didn't work. I've never tried brake line pliers. I've always used a socket in a vise and that seemed to work. But this time I had to do some very difficult corners and had very little space to get to the area where I was working. I was absolutely amazed at how easily these pliers made my job easier. I love my instruments and have a lot of them. But now these pliers have a special place on my workbench because they saved me so much time and nerves. They arrived on time, in perfect condition and did not damage the brake lines in any way. Also, the jaw was in perfect position. I would buy from this seller again.
