Hello John, As an aside to your question, I have just replaced the brake master cylinder on my Vitesse with a 0.75" bore unit and the pedal feel has improved 100%. I had previously changed the seals in the original unit but it remained spongy so got a new one off eBay (Landrover unit at 12quid delivered) and love it. I dont know if its just down to the bigger bore or cos its new but at that price its not worth messing about with seal changes! Hope that helps, Graham
