• “Lightly sparkling brakes”

  • Does the syringe screw or press in to the lever?

    Is it possible air is coming in at the point where the syringe connects to the lever? Dodgy seal at that point?

    You have used these syringes quite a lot (lol) so maybe seal on the syringe has degraded.

    Your perseverance with these is astonishing :)
