A bit of thought-sharing appreciated.

I have fully rebuilt the brake system on my 1973 164 fitted with ATE brakes & master c. Trouble is despite repeated bleeding by the book, following the order of bleeding to the letter, the pedal is still soft, the brakes next to useless.

I’m at a bit of a loss where to look next. One specific question - the small bolt on top of the master cylinder that acts as a lock for the piston assembly - is that also for bleeding the master cylinder? Openly I’ve not experienced needing to bleed a master cylinder but cannot think what else might be needed?

Any other thoughts?
