I'm rebuilding a brake master cylinder off a Victor ( F-Type 1960), got hold of the rebuild kit but don't have a workshop manual, yet.
The pump aint pumping! There's pressure there but fresh fluid isn't flowing into the cylinder. The way is clear from the reservoir but it's just pumping air not refilling. Also the three holes in the piston are clear.

I've tried the shim both ways but no dice. All seems to go together ok but have I got something wrong?
