I asked for opinions on the DML list but got no concrete replies. I removed the servo, checked for leaks, (none), checked for any apparent vacuum leaks elsewhere, (none), reassembled and no difference. There is obviously some servo assistance, but not as much as one might expect. This does not worry me unduly as I like to have some feel in the braking, but I suspect it is not as it should be. The only possiblity might be that I know the master cylinder on my car is not original and it may be that the replacement has a very slightly larger bore than the original design which would mean a greater force required for equivalent braking which could make the servo appear to not be working adequately. To check the vacuum for leaks you will need a vacuum guage.

I have also totally bled the system and there is no air in it, The only thing left is the power assist. How do I check the vacuum is working right, or is that not right in itself?
