Typically on a 6-Piston caliper, there are two of each piston size, so this combination should service two front calipers (12 pistons total). This kit is assembled specifically for the 2008+ E82 BMW 135i; however, these may also work on other applications. This kit will may work for many aftermarket Brembo or StopTech 6-piston caliper combinations.
