This is a very good used Saab OEM tool for the New Generation Saab 900 and early Saab 9-3 rear brake caliper pistons. This holding tool works on all 1994 - 1998 New Generation Saab 900 cars and the 1999 - 2002 Saab 9-3 cars as well. This tool is used when removing the rear brake caliper pistons for resealing, and was part of the original Saab tools that were required for dealer service departments.
