Brake fluid recommendation?
Just wondering what people are using for brake fluid these day's? Ate super blue seemed to be what most were using before it was banned (ate type 200 is the same I believe?) and I've seen some have been using motul rbf600 but am Leary of the short interval changes. Getting ready to install my brakes (nx2k fronts and converting to rear disk ad7ha). The car will be mostly daily driven/ maybe some autox in the future. Also I'm replacing the rear line's and am wondering about how much fluid I will need to flush the system completely. Thanks Dave

For a mostly DD with limited Autox vehicle, in all honesty, any ol brake fluid will do.

The idea behind the high temp stuff is repeated stops from a good clip (above 100-120 mph per say and mashing on the woooahhh pedal). That generates immense heat which is localized by the piston/brake rotor........which so happens to be where the fluid sits. This boils the lower temp rating fluids.

In short, you won't be seeing anywhere near that amount of heat abuse.

As far as what I have used: It all depends on what I get a deal on (my car sees a good amount of track days and 140+ MPH to 50 MPH repeated brake stomps on the track). I have used ATE blue, RBF 600, RBF 660, Wilwood 600, and ATE Yellow (what replaces the blue). Have had ZERO issues with all the models and variations.

Thanks for the explanation on the high temp fluids. So any dot 3 or 4 would be ok but dot 4 would be the more preferable as it has a higher boiling point? Thanks Dave

Correct, It seems dot 4 has a high boiling point, but really, you should use whatever is compatible with your vehicle

Same question here, have a P11 with Z32 front calipers, Stainles brake lines and now i want to try a better brake fluid (was using the stock one).

I was reading that ATE Blue was replaced by ATE Yellow (or ATE Type 200?)?.

I read the same thing. Typ200 replaced the blue. It also recommends a change interval of 3 years I believe instead of the 6 months the rbf600 is suggested. I've decided im just going to grab some dot 4 for now and If I decide to become a little more track oriented then i'll flush the system with something else. Dave

Most people I know never change their brake fluid! And then they wonder why brake lines rot...

The trick is not what brake fluid to use, but how often to change it. 3x per decade should be what to aim for!

i replace and flush annually around april/may, it also helps me keep my brake bleeders from becoming seized up

i use dot4 fluid in my car. It can be used in DOT3 systems without worries. I use this brand named "Spectra" but i cant seem to find it on the web.

It works great and I have not had any troubles with it boiling and sometimes im rather abbusive to my break system.

I also change my fluid anually or a little before if it is looking really dark and nasty.

I run about 6 HPDE's a year in my cars and previously used ATE Blue/Yellow. Now I use AP Racing Super 600. Try a moisture testing device to know when it needs replacement if you don't want to do annual or biannual changes.

This is what I currently use for testing:
