Thanks guys I forgot to mention I have 2 new boosters and I have checked freeplay on the rod.

most likely to be the bleedback on the master cylinder

Series 1 & 2 have a single cylinder but dual system .Bristol years ago used to carry stock of repair kits but are nearly 50 years old and don't last. Series 3 4 & 5 have a different cylinder as best I can gather and im sure could be adapted. Does any one know what other cars either of the cylinders are common too.

Any clue on tie rod ends
