maybe this will change your mind http://superchevy.com/technical/chassis/brakes/0509sc_fluid/ anybody have any more technical discussions for brake fluid?
i'm considering this too, i've heard it's the way to go if you're going to do track/auto-x... i wanna hear someone less ignant than me chime in though
I use DOT 5 and will keep using it. I don't go for the ABS issues he raises. And most of his other issues revolve around getting water in the lines. Well it's a trucking site so offroaders may deal with water more. And most of us don't let the brake fluid sit in the car for 4+ years(right?). However, if you don't do track days or aggresive downhill mtn. runs (ahem) DOT 4 should be fine. The important part is at the end of the article... Minimum Dry Boiling Point/Minimum Wet Boiling Point (All degrees in Fahrenheit) DOT 3 401 28 DOT 4 446 311 DOT 5 500 356 And if the non-absorbed water in silicone boils 1st, wouldn't it rise to the top?
Something else to remember when you use Dot5. When you crack the seal on the bottle, you can't close it up and use it 6 months later. You've got to use all that you're going to use within a couple of days. Motul can be bought at a number of local motorcycle shops. You could also look at ATE super blue and their gold fluid as well. Makes it very easy to see when you've completely flushed the old fluid out.
Hmm. My pedal was a bit mushy at the track day so I'm think I need the braided lines.... and maybe different brake fluid.
For 100 bucks, you really can't beat the braided lines. I think that any brake fluid better than the Motul is gonna be $$$$.
