Wrong brake fluid used ??
#21
Its interesting, this debate....I put the mix into a jar to see what happened and how long it took but nothing has happened.....I am wondering if it needs pressure to set off the reaction. Also, I have found the dreaded turquoise jelly in two bikes that were running Dot 5 on its own but both had lost a lot of fluid and the jelly formed as a result of the Dot 5 drying out.
I'm not saying it doesn't happen but I think its a reaction with the seals that causes the problems and the jelly is rotten rubber or something.
I have some old brake parts, I might add my mix to a brake system (off the bike) and do some more testing...

More alarming than mixing the fluids is taking DOT3 or DOT4 and adding water. See how much they will take up before the water separates!

Yeah, that's the problem with DOT 3/4. It absorbs water out of the atmosphere, lowering the boiling temp and rusting everything it touches. DOT 5 doesn't absorb water. SOME racers don't like DOT 5. The extreme high temps of car racing may not work well with it versus a DOT 4 or other fresh racing brake fluid. On a bike, it wouldn't be a problem. I am now converting all my hydraulic clutch systems to DOT 5 as they need servicing. I did the Corolla a few months ago.
