once the large bubbles at the caliper have stopped, apply a
small amount of pressure on the syringe plunger and slowly let
the pressure extend the brake lever you have been holding
with your finger. if you fastened the lever with a zip-tie or
rubber bands, remove these first but keep the lever pulled in
with your finger, then apply pressure on the syringe plunger.
You will feel the pressure at your finger on the lever, just let
the fluid extend the lever back to its original position.

Close the clamp on the caliper syringe, then remove the
syringe from the caliper and re-install the bleed port screw.
Use a clean rag to wipe off any excess DOT fluid that spills
out as you re-install the bleed port screw.

Pull out on the lever syringe plunger to create a vacuum, then
gently push in on plunger to pressurize the system. Squeeze
and release the brake lever ten times, allowing the lever to snap back
to its starting position after squeezing (this helps break loose the bubbles).
Repeat this procedure of creating a vacuum at the syringe and
squeezing the brake lever ten times until large bubbles stop
coming out of the lever.
Do not pull out too hard on the plunger or you will suck air past the plunger
seal into the fluid and create more bubbles that you will have to eliminate.
