Proceeded to rebuild the master cylinder upon receipt of the rebuild kit. Everything looked pretty good in the old cylinder bore....some rust which was carefully removed with crocus cloth....completed the master cylinder rebuild and installed it. Spent hours attempting to get the cylinder to pump oil...no luck...took a nap instead.
Finally used a syringe to force fluid through the cylinder pistons. That removed the air lock in the cylinder. Once that was achieved the caliper pistons pumped right out. Cleaned up the pistons and bores and reassembled. Rebled the system and now we have brakes!...Finally!
