ending bracketpedal on final \bar "|."

[Atte André Jensen]

I need to end last pedal on the final barline. The following example 
just needs the "\sustainUp" but where to place it????

Thanks in advance for any feedback!

\score {
    \notes  \relative c {
        \property Staff.pedalSustainStyle = #'bracket
        \clef bass
        | a2 a
        | a a
        | a a
        | a\sustainDown
        a\sustainUp\sustainDown
        \bar "|."
    }
}
