By the way, we have purchased some clear plastic tubing to place over the bleeder fittings to keep that job a less messy one. Will be showing that technique in a future post.

Hi Jim

Yes the provision for filling the master cylinders starts off in the Pattern 11 being difficult and very slowly gets better through Pattern 12 and 13 only being made reasonable I think in 44.

What you need to do is make up one of the filler bottles shown in the manual.

A reasonable substitute can be made with out of a brake fluid container and some copper tubing. Back when brake fluid came in a steel can with a steel top I made up one by soldering two lengths of copper tubing in the top of a top one of the tubes was 3/4 of inch shorter than the other. When you insert the can upside down with the tubes sticking into the cylinder the fluid runs into the can until both tubes are covered by brake fluid. Then as you bleed the system and the fluid level drops the short tube is uncovered and lets air into the can allowing just a bit of brake fluid into the cylinder. I'll try and find mine and take a photo.
