Hiya guys, thanx to Kenny for your input ,spoke to a jag expert yesterday about my problem and he said that it could be the pedal free play needs adjusting, he said to screw in the nut on the end of the push rod but neither the master cylinder or the servo have an adjustment nut on them so does he mean the push rod from the pedal to the servo unit or what it was confusing any body any ideas on what hes talking about ??????,.

Cannot help you there Paul not having your model to check although I wouldn't be looking for a adjustment nut on the servo. Have you looked at the back of the pedal, which would normally be the push rod. I have made such an adjustment on previous manufacturers vehicles.
