Review on 🔧 ABN Ratcheting Caliper Piston Tool: 4-in-1 Universal Disc Brake Compression and Spreading Tool by Andrew Jenkins

The biggest problem is how stiff and steep the ratchet is. Basically you have to hold the parts (plates and threaded shank) together by hand so they don't move with the ratchet. Once a lot of pressure is applied to the plates they work as expected, but the same problem occurs when the tension is released. Disappointment and somehow self-destruction. Spend a little more and get a tool that really works as intended.
