You are welcome Ron, it was easier to provide that one because I have a loose leaf copy of the Aston DB5 workshop manual that the information came from.
I have now taken the Bristol 407/408 Workshop manual apart and copied the section covering the brakes and front and rear suspension - you might find that information useful too. Again it's an external download link and it is in the Resource section of the site
here
The disc brakes are the same as those used on the Mk2 Jaguar (but not the Mk1).
