; Newer brake lever model
: [[File:Brake lever tagged.jpg|thumb|none]]
: Newer replacement parts seem to contain an extra screw (G) used to fit the length of the piston (E) into the cylinder.
: With this replacement part, assemble by:
# Put part D into the lower hole of the lever (A).
# Screw the piston (E) into the visible hole of part D.
# Put the rubber boot (F) onto the piston (E), so that it looks like in the assembled version shown before.
# Screw the small screw (G) from the side into part D to fix the piston (E).
#: Keep it loose, though, so that you can still screw out or in the piston (E).
# Slide the lever into the bracket as shown before.
#: Insert the hex bolt, but do not tighten it.
# Check the function of the brake, especially any slack it shows.
# In case you have slack, take out the hex bolt, slide the lever out again and adjust the length of the piston by slightly screwing it out.
# Reassemble into the bracket and recheck the function of the brake.
#: If you are happy with it, then tighten the small screw (G) to fix the length of the piston.
