I am now wondering whether it is necessary to fit a vacuum tank with a newer servo. Not having vacuum wipers or washers and now using a slightly more modern servo with built in non return valve I can't immediately see the need.
Also I'm interested to know what ratio servos others use with disc brake conversions. I have a 4.25:1 on my 403. It balances the light throttle pedal pretty well but it's probably more assistance than necessary. I fitted a 3:1 on my 401 and that seemed ok for the short distance I drove it prior to sale. I think the 401 had a 406 pedal box fitted so it would have had more mechanical advantage than an original 401.
All this leads me to the decision that 4.25:1 will probably fit the bill for a 400 with original pedal box. Opinions, please!
