When you are at an engine idle speed, a worn pump will not produce what it will when rev'd up.
The old Jag sedans used a small steel vacuum tank, and there are accumulators that look like and egg carton. I suppose if you want to keep it stock, you had better look into a rebuild kit for the pump. It's not the sort of thing the regular stateside suppliers would stock, but Blanchards, in the UK ought to be able to help you.
Thanks, thats kinda what I thought. I remember my old VW Jetta diesel (1982) had the egg carton type of accumulator for all the dashboard switches (Heat/Vent/AC), but I never had an issues with the brakes. I guess the accumulator for the rover is smaller. I guess I just need to modify my braking style to be steady vice pumping.
