You have a reference for that?I would stick with Toyota DOT 3 fluid. Some of the racing fluid or the like doesn't hold up as well for the street and needs to be flushed regularly.
DOT 4 is more viscus and not recommended. Unless you are experiencing fluid fade there is no logical reason to buy expensive fluid.
DOT 4 will out perform DOT 3 when new and will, at worst, perform the same as DOT 3 as it absorbs water. You should be replacing your brake fluid every couple of years anyway.because it absorbs less water than DOT4, it is less expensive than DOT4, for street use it is perfectly safe and will last longer as it absorbs less water.
Yes I do however it is in the search where I went into detail with links. I would like to look it up however I have been very busy lately to do the research again but it's out there.You have a reference for that?
DOT 3 and 4 are both hygroscopic. DOT 4 has a higher boiling point (wet or dry). Race cars change oil more often too. That doesn't mean that the oil they use is inferior for street driving.
I don't think price is a big difference, compared to what you pay for pads and rotors. Question is, why would anyone buy DOT 3 brake fluid haha.
You cant go wrong with any good DOT3 fluid however I would stick with Toyota brand only because it's quality fluid and designed with the right formulation for the seals and everything else.The car is sort of for daily driving. I was thinking of getting a good brand of off the shelf from autozone or pepboys. Has anyone use a different brand of brake fluid? Or, should I stick with toyota brand?
just use something from autozone.. im using valvoline dot3&4 "synthetic" so far so good. im on stock brake lines and random ceramic pads.... soon to be upgrading my pads and lines to ss lines though. but imma still just stick with cheap fluid for daily drivingThe car is sort of for daily driving.

I missed this one. Oil that is used for racing (depending on the kind of racing) is formulated very differently then street oil. They trade short term extreme durability for longevity in their formulations. I have experienced this first hand with "racing transmission fluid" where it did not last longer then a few months before my transmission became loud and the synchros were not engaging properly.Race cars change oil more often too. That doesn't mean that the oil they use is inferior for street driving.
Well that's a different kind of DOT 4 fluid. It's what they call a low viscosity DOT 4 . The aftermarket DOT 4 is viscus and can cause problems in the cold and some say a problem with the rubber seals.DOT 3 and DOT 4 have almost the same formulation except DOT 4 has some extra checmicals to raise the boiling point. DOT 3 is being replaced by DOT 4 fluids. Luxury cars are making the switch so the common man's car would soon follow trend. Cost is the same so either way you go, you should be ok.
You should be flushing your fluids every few years anyways...
