Hi I have sorted the problem it wat the tee junction on the vacuum pipe where it joins with the break servo that was blocked causing the issues I had

Excellent work. Did you discover what the blockage was and where it had come from?

Yes the the vacuum reservoir had come off and melted on the exhaust so had to replace it
