Any advantages or dis advantages to using dot 5 in my new 01 gasgas 350??? thanks J Sheets, ps your tips are the best!!!!!


I like the DOT5 as it doesn't damage paint and is less likely to absorb water, which deteriorates braking and rusts internal components of the system. If you change over, flush the system well with the DOT5 and pressure bleed it from the servo cylinder (lower) up to the master cylinder. Jim Snell of Rising Sun Imports informs me that the fluids will mix o.k. so don't worry about a little DOT3 or 4 left in the system. I used to worry about residual fluid in the system, but if Jim says it's o.k., that's good enough for me.

I understand that there is DOT5a and DOT5.1 available in Europe and sometimes here in the States. It is a lower viscosity and therefore is less restrictive in the lines, adding to the "feel" of the system, especially the clutch. It's used in the hi-speed ABS systems of the "Autobahn Specials" they run over there. I figure I'll chum up to a Mercedes mechanic and see if I can score some to try!
