Only for the large style, dual piston Wabco caliper.
Photo shows four bellows, but the kit includes only two bellows for one caliper.
Order two kits if you are doing two calipers.
See the caliper and brake pad identification page, if you are uncertain as to what caliper type you have.
The large Bosch calipers have FOUR slide pin boots/bellows.
The Wabco calipers only have TWO boots/bellows per caliper.
