I've bought all new brake components and have read the dot 5 is not good to use. But dot 5.1 is ok. Am I reading this correctly? Or should I just stick with plain ol dot 4?

Valvoline Synthetic...pick it up at Vatozone.
Unless you're at the track every day, DOT 4 should be just fine and then some. Just remember that once you go to DOT 4, you need to stick with DOT 4 or better - don't go adding DOT 3 to DOT 4 (at least that's what I've always been told).
And +1 what sammm said about the Valvoline Synthetic...
+1 Good Stuff!Quote:

Magma is also running this in his MSM.
Ok, I'm a snob I guess.... I use Motul RBF 600. The higher boiling pressure is nice, but the resistance to moisture is what I like best.
Just so you dont think I throw money away, I don't pay any where near retail for it.
Another vote for the Valvoline.
+1 ::Banana::Quote:

FWIW, I use Valvoline Synthetic on my cars for daily driving and autocross use, but I'll flush the system with Motul for track days.
Oh, and real brake fluid snobs use Castrol SRF. :wink:
you cannot mix dot 5 with anything but dot 5 because it is more silicon based. you can interchange 3 and 4, but if youve got 4 in there you might as well keep 4 because of the boiling temp.

The only think I could keep from eating all of the seals out in my old FIAT was Castrol LMA which is a Dot 4 brake fluid. Haven't tried Valvoline, but will definitely will give it a try, now with the overwhelming recomendation of the group here.
Hmm...interesting info, thanks!Quote:

dot 5 supposedly does not absorb water. and it doesnt disolve paint!
Go ahead and use some Skydrol.
It's purty Purple and full synthetic. JK
I use Motorcraft High Performance DOT 3. Great stuff for the price, $4.20 for 12 fl. oz. at any Ford dealer, 550F dry and 288F wet boiling points. Not bad when it's changed as often as we do.::StirTheP
It is also a highly compressible fluid, which equates to a very squishy brake pedal. Dot5 fluid should be completely avoided on all tracked or autocrossed cars, imho.Quote:
