Solid Product & Performance
Their brake fluid never fails to perform. I flush every 3 years or so and not only is this a good price point but definitely doesn’t absorb much water & I’ve tested it for water absorption. Solid product, you can’t go wrong here!

Great for Clutch Fluid Changes
Use this whenever I change the clutch fluid on my 08 Corvette and it has been great, no issues whatsoever. Came sealed and for the size, I think the value is quite good. I'll be purchasing more as soon as this bottle runs out!

Very low moisture content
I tested this brake fluid for moisture content before changing my existing fluid, which was full of moisture after only 2 years. This fluid had zero moisture when opened. I read that DOT 4 fluid absorbs more moisture than DOT 3, and I believe it. I do like the performance of the DOT 4 fluid. The pedal feels firmer and it is more heat resistant. I'll just change it every 2 years. I have speed bleeders on my 2013 Tacoma, so bleeding brakes is really easy.

Not as good as Motorcraft DOT 4 brake fluid - but good enough.
This DOT 4 is a little under specked, but I do not plan to drive in the mountains anytime soon. The Ford spec for DOT 4 fluid is more strict than this product - in terms of heat. The driving I do in the city/highway is more than good enough for this product. Will see how long it lasts before too much water gets into the brake fluid again.
