Review on Lisle 28600 Brake Caliper Piston by Danny Kamerer

Job done. I used the side of the cube with 4 notches on each corner. Simply attach to a 3/8" ratchet with extension, insert this cube into the notches of the caliper piston, then turn clockwise while pushing. It took me a minute to figure out that it worked and then gave it a full bean, but when I did it worked perfectly. Again, no tools are required other than a 3/8" ratchet with extension - I think I used an 8" extension, but anything over 4" should be fine to give you room to move the ratchet to turn. Must be PUSHED when tightening the ratchet.
