DOT 3 vs DOT 4
 

Heard DOT 4 has a higher boiling point. Is there any other benifit to using DOT 4 besides that?

I don't think I've ever boiled DOT 3 on the street.

dot5
silicone based!!
i know people that are using it on their cars..and they swear by it..

Yikes really? I heard it can damage your components!

my dad's been using it on his '66 T-Bird for a few years..
guy at work has it in his old Vette..
another at work uses in his "Lambo'd" Fiero..
i used it in my bike..

news to me..but i'll be switching over the Si when it comes time..

oh..and don't take my word for it..

definitely source it out before thinking about it..i would..

.... are we talking about oil here?

i know i know :richslap: but i don't know much about oil except that you need it in your car

they're talking about brake fluid :nods:

the higher the DOT generally means a higher boiling point, thus meaning less brake fade under hard braking conditions :)

Ive had the fluid boil aright. Its dot 3 I think. My friend had it done and he said he highly rocomends it.

Once you get into DOT 5 you usually have to change the brake lines to stainless steel or something that will be able to withstand the heat..

So if I haven't experienced fluid boiling over than is there any other performance improvment in upgrading?

Ford Brake Fluid serves many, quite well

dunno, what are the compression ratings on 3 and 4??
if one has a greater compression point then it'll be more effective when really laying into the brakes..(hydraulic power..)

and ya KSR is right on the money..
stainless!!
but it's not that expensive :wink:

dot 4 doesnt soak up as much moistuire as dot 3 and therefore doesnt rust the brake linbes from the inside out as quick.
