Any DOT 4 fluids must meet those minimum specs. Here's the NHTSA's paper on brake fluids, specifically look at section 5.1.1: https://www.ecfr.gov/current/title-4...ection-571.116
Just as a reference, I recently took my 2020 to Sterling BMW for scheduled service for warranty purposes. Part of the service was the brake fluid and they used Justice Brother's DOT 4 brake fluid. |

Sure, that is correct, but the OP is referring to wet and dry boiling temps, regardless if it's LV or not, they still need to meet "DOT4" specs. Shoot, even the cap only says DOT4. Plus, it doesn't stop people from using racing brake fluids, which most are all DOT4 (non-LV) spec'd anyways.

Plus dot 4 brings in fluid with a higher working temp which is nice when you want to do autox, light track, and street useage on a single fluid. It saves the pain of flushing fluid all the time.

So probably best to daily it on dot 4 lv just to be careful, because it isn't a quiet squeak that can be ignored, its a loud annoying squeak. Well guess my 4 jugs of ate will have to be sold lol...

https://www.ate-brakes.com/products/brake-fluids/ Actually the Bosch ESI6 is the best street option on paper. Seems to be a tweaked / slightly improved ATE 5.1. Last edited by chris719; 01-04-2024 at 02:42 AM.. |

It's strange though, for some reason I only have heard of this issue on ate typ200, nothing else causes the squeak from what I'm reading. Pretty annoying but what can you do, plus side is it's only with ate typ200, so you're still able to use other dot 4 fluids for the track. Hope I can sell my ate stock, it wasnt really cheap buying it and shipping it to Canada lol. Edit - sold it to a vw owner, pretty much sold it for nothing lol.

For standard fluid I use Pentosin LV. I can get a liter at any Autozone store for ~$16.
Since I daily my car through frigid Minnesota winters, I put LV fluid in every fall, along with an ABS cycle. It might not make a huge difference from track fluid, but if I'm driving on ice, I want the ABS/DSC to work as well as it possibly can. Then, in the spring, I put in the Castrol SRF when I put the track pads on, and I'm good for the summer. Since SRF should really be flushed every year this keeps me on a good schedule. Am I diluting the SRF with residual LV? I'm sure I am. But not enough that it is affecting the calipers which get full flow when flushed. And SRF is fully miscible with standard DOT 4 fluid, so I don't worry about the minimal mixing going on. I also make sure to drain as much fluid from the reservoir as I can between fluids to keep mixing to a minimum. Have a long skinny tube on the end of syringe to get deep in there. (And don't forget to refill the reservoir with new stuff before bleeding! ) |

Yeah it seems to happen on some cars. Not sure why or how.

I agree this is probably the best way to do things. It's more work and money switching back and forth, but atleast you don't have to ever worry about the potential of getting a squeaky pedal.
