Gilrling caliper rebuild problems 140-160

Hello All. I am in the process of redoing all the brakes on my 74 145. It was sitting for close to thirty years so the Girling calipers are well overdue a rebuild.

But after a couple of days of head scratching I am still stuck. I have managed to get the pistons to move in their bores, but I cannot work out how to get both pistons out of the caliper. Of course I can get one out, but then I cannot build any pressure for the other. And, if I push two opposing pistons out, they touch in the middle of travel and neither will release.

In the green book, it is suggested that I release one piston then cover the hole with a rubber washer and tool 2809 to build enough pressure to release the other. I don't have the tool but have rigged something equivalent and no dice.

This whole thing is reminding me of those infuriating puzzles that my Uncle Jim used to bring to Christmas dinner. Seems like there is a simple solution but I can't work it out.

Please put me out of my misery.

Any help or guidance most appreciated. Warren
