RE: Dot 3/Dot4 Mis

["Avi Meron" <avi@cosmoslink.net>]

Trish,
99% of dealers  (new car dealers) in the field, MIX brake fluids without a
problem, never heard of any (I see new dealers EVERY day), the mixing of DOT
3 and DOT 4 does not seem to cause any problem, BTDT for many many years,
the only thing you have to watch for is DOT 5 also known as SILICONE brake
fluid, SHOULD NEVER BE MIXED with DOT 3 and 4......
