You didn't specify model year (or I missed it). I can only answer for '05.

The assembly consists of:
Bolt - washer - flexible line fitting - washer - caliper.
Sometimes a "U" shaped double washer is uised in place of 2 single ones. The "U" fits over the end of the flexible brake line, so you end up with a washer on each side.
The washers are typically crushable copper and only intended for one-time use. Re-used washers sometimes leak.
