Here we go again! Let me start with this. I have been using DOT 5 in my 71 Spit for over three years, I haven't added fluid or rebuilt ANYTHING. DOT 5 is silicone, it will not eat paint, the boiling point for silicone is much higher than DOT 3 and 4, it COST MORE. You will need to do a full cleaning of all lines and cylinders. You will be very happy with the conversion once it's done.

The manuals, caps, spec sheets, etc. all say to use DOT 3. The majority (if not all) listers/owners say use DOT 4 (which I did) because of the "melting" affect DOT 3 has on the natural rubber seals Triumph used. Over the years I've never rebuilt any hydraulic components on my 3A, except a leaky wheel cylinder about 10 years ago. Occasionally I have topped off the reservoir with fluid, I'm sure I've used DOT 3 for many years with no adverse (noticeable) affects. It's not a daily driver, maybe 2K a year. Were there changes along the way in the rubber used in the earlier models, or was all the rubber used over the years "natural," and why? Is DOT 3 in any year/model an accident waiting to happen?
