Brake Fluids Comparison Chart

Hey I found this doing a search...hope it helps: Brake Fluids

 

Nice find. I like that he included boiling points after 6 mos. in the car. It's like it was made for VR4 owners... even breaks it down into $ per degree. /ubbthreads/images//graemlins/grin.gif

haha yeah I found it pretty nice...I chose to go with the ATE Super Blue

I run ATE blue in my rally car... Always seems to work good...

I've used the Motul, Wilwood, Ford, ATE, and Valvoline at the track. I'm currently using the Ford because it's $3.50 per bottle and the dry boiling point is very high. If changed frequently, the wet boiling point doesn't really apply.

im running ate super blue in my car. no opinion yet, havent run the car hard enough to give one.

I like that chart. I especially need to find out which ones have the highest boiling point after a few months, as the DOT 4 doesn't seem to last long in my clutch (GTO) with the Valvoline Syn...gonna try some of those others.

The ATE is pretty cool for cars that get frequent brake fluid changes. The "Blue" and the "Type 200" (Amber) are chemically identical - they're meant to be switched between, so that you can easily see when you've flushed all of the old fluid out.

The blue stuff isn't technically DOT legal. The dye is the reason. Also, on cars where the brake fluid and clutch fluid use the same reservoir, bad things can happen with the Superblue. It's been known to kill Audi clutch hydraulics. It did in my 97 A4 1.8T. The clutch system got really grainy and felt like it had sand in it.

The super blue does meet DOT 4 standards - the problem most likely comes from either mixing DOT 3 and DOT 4 fluids without fully flushing out the DOT 3. Either that or leaving the DOT 4 in too long, since it degrades much faster than DOT 3 does.

Also, common reservoirs for brake and clutch are a poor design (german "elegant design" gone wrong) since brake fluid takes a lot more abuse than clutch fluid, both systems get cross contaminated. When you change the fluid to bleed the brakes, you must also bleed the clutch system *every* time.
