Air Brake Piston Resetter, No. 468 026

The Mueller-Kueps Air Brake Piston Resetter, No. 468 026, helps alleviate the issue of finding the correct reset disc when resetting brake pistons. This kit comes with two uniquely designed adjustable discs. A two-pin disc and a three-pin disc are both made from extremely durable steel, designed to accommodate almost every brake piston. This tool works for both left and right threaded pistons. To use, simply place the disc against the brake pistons and rotate the basic unit until the pins fit into the bores. Then attach the discs by way of strong magnets nestled in the head of the resetter. The compressed air provides a constant pressure and will not damage the thread in the brake piston.
