ATE Original SL DOT 4 Brake Fluid, 1 Liter Can (705802)

great brake fluid for track applications, worth buying

It works for track and street. Great stuff.

Ate is always the best because it’s easy to see when you’re done.

Great product.

Good product. Use it in my FP Miata and Formula Mazda

I tracked with ATE Type 200 DOT 4 many times without any brake performance issues.

all right, this is going to be a bit convoluted, but I feel the public service is needed for people to avoid the same ordeal I had. I'd used ATE typ 200 in my older 2003 A4 and it was great. I didn't bother with it when I had my 2013 S4 because I was using Castrol synthetic Dot 4 that worked well and came in 12oz jars so i could add a little extra to my bleeder to make sure i totally flushed the old stuff. That doesn't seem to be available any more, so I went back to this one when I got my 2022 911 992.That was a mistake. Now, on the reservoir cap, my 911 says just "dot 4" (and the manual is useless, just tells you to go to a dealer). However, while I had not kept up to date with the latest stuff on brake fluids, i had heard something about "low viscosity" dot 4 fluid, and THAT is what is actually needed on my car, and really, most modern cars with ABS and traction control systems. Why?Viscosity is how thin it is, how easily it flows. Normal brake lines have a set diameter. However, when fluid goes through ABS modules, it flows through smaller holes and lines. So it needs to flow easier - with lower viscosity, especially at low temps. Otherwise, it could develop air bubbles as it struggles to flow through. Regular dot 4 has a -40 Celsius rating of max. <1500 mm2/s. DOT 4 class 6, aka, LV is half that at 750. I didn't do this research ahead of time. I bled my brakes with the ATE typ 200, and when i got in my car and pressed the brake pedal, it squeaked to high heaven. So now i need to rebleed them with LV fluid.Having said this, if you are tracking a car, it probably doesn't matter because at upper temps, like what you see while tracking, the viscosity is pretty similar. But for regular driving, probably want to stick with LV fluids. ATE has an LV version, as does Pentosin. Bosch's regular dot 4 ESI6 meets the specs too, but it's not labeled as LV for some reason. Just read the specs. look for a viscosity rating of <750 mm2/s at -40 Celsius.I rated this a 4 because it IS great dot 4 brake fluid. However, it seems to be the only one that causes that squeak with newer cars, while other dot 4s do not have the same number of complaints. and like i said, I didn't have that issue w/ my Castrol on the S4.

Good value performance brake fluid. Was used in my Camaro track car and now in my Challenger. I will use in my CBR1000RR for track use as well
