@EBC Brakes Nice video, but one technical error on the DOT brake fluid ratings. DOT 3, 4, and 5.1 brake fluids are based on glycol ether or borate ester compounds. DOT 5 is a silicone-based fluid that is not compatible with ABS systems, cannot be mixed with other types of brake fluids (I believe the entire system needs to be flushed with alcohol first if changing to DOT 5), and it does not absorb water like glycol- and borate-based fluids do. It is typically used in military and extreme cold applications, though some vehicle museums use it because it does not damage paint work.

I'm not sure if DOT 5 is even available in Europe, but it is in the US. So we need to be specific and always distinguish between DOT 5 and 5.1 when talking brake fluid here.

Good point Dave_W, as folks often think if DOT4 is good , then DOT 5 must be even better. Drivers should be cautioned to not even use DOT5 in my estimation, since the confusion could lead to someone mixing DOT 5 and 5.1 ( fortunately DOT 5.1 is fairly hard to find ). As Dave_W noted , though , the silicone based DOT5 is just not a good alternative for ABS and other uses, and 95% of Trackrats use a high temp DOT4 for road course and autocross use.

Very good point, thanks for raising. We offer three varieties of DOT 4 and both DOT5 and DOT5.1, with info regarding each found through our website at this link.

We used to run dot5 in the old, pre 80s corvettes because they had so many issues with those old calipers corroding internally. Stainless inserts fixed it for the most part.
Yep. My C-3 vettes have run Dot 5. Rust kills those calipers.
