Well, LilyPond's way of doing pedals is a bit ugly. You could try 
something like

\version "2.22.2"

\layout {
  \context {
    \Staff
    \override SustainPedal.stencil =
      #(lambda (grob)
         (let ((text (ly:grob-property grob 'text)))
           (if (equal? text "*Ped.")
               (let ((font (ly:grob-default-font grob)))
                 (ly:stencil-combine-at-edge
                  (ly:font-get-glyph font "pedal.*")
                  X
                  RIGHT
                  (ly:font-get-glyph font "pedal.Ped")
                  ;; padding value
                  0.5))
               (ly:sustain-pedal::print grob))))
  }
}

sustainOff = \tweak non-musical ##t \sustainOff

{
  c'1\sustainOn c'1\sustainOff\sustainOn c'1\sustainOff\sustainOn 
\break c'1\sustainOff
}
