What you need is \defineBarLine:
http://www.lilypond.org/doc/v2.18/Documentation/notation/bars

\version "2.18.0"

\defineBarLine ":|.-.|" #'(":|." ".|" ":|.")
\defineBarLine "|.-.|" #'("|." ".|" ".|.")

music = \relative c' {
        \key c \major
        \time 4/4
        \bar ".|:"

%Part 1
        \repeat volta 2 {
        \partial 8 a8
        a4. a8 b4. b8
        c4. c8 d4.
        \break }

%Part 2
        \bar ":|.-.|"
        e8 |e4. e8 f4. f8
        g4. g8 a4.
        a8 b4. b8 c4.
        \break

%Part 3
        \bar "|.-.|"
        a8 |
        a4. a8 b4. b8
        c4. c8 d4. \bar "|."
        \break

}% end relative
