Wow, finally able to connect (long story)... I've owned a 1976 L206D British van conversion called the "Ultra Autobahn" for over 40 years (KatieKat Website Myrtle) and stumbled upon this site and still playing catch-up. Been in mothballs but runs fine (20-year-old fuel via super filtration). Have all the factory workshop manuals, and would like to discuss source(s) for obtaining brake cylinders (at least one, as the others should be rebuildable) and relining the brake shoes, and what type of diesel fuel should I use for this OM615 (I think) engine? Thank you.
