Brake caliper assembly - extra rubber part?

Hi everyone,
I just got my calipers powder coated (in a ball joint/bearing/brake overhaul at 105K miles) and am in the process of putting them back together/rebuilding them.

The kits that I bought from rockauto.com came with an
1) Inner-piston Seal
2) Outer-piston Boot
3) Outer boot retaining ring
4) Bracket boots (2x) and
5) 2 Small rubber caps/ 2 rubber sleeves (front)

Where do the small rubber caps/sleeves go? I've looked through the parts I dissassembled and couldn't find anything that looked like what came in the kit. Also the workshop manual shows only 1) 2) 3) & 4).

Would they happen to go around the bleeder screw?

that was my thought, remember them on mine.
