​
DOT 3 is one of several designations of automotive brake fluid, denoting a particular mixture of chemicals imparting specified ranges of boiling point.
​
In the United States, all brake fluids must meet Standard No. 116; Motor vehicle brake fluids.
[1] Under this standard there are four Department of Transportation(DOT) minimal specifications for brake fluid.
They are DOT 3, DOT 4, DOT 5 and DOT 5.1.
​
DOT 3, like DOT 4 and DOT 5.1, is a polyethylene glycol-based fluid (contrasted with DOT 5, which is silicone-based).
​
Fluids such as DOT 3 are hygroscopic and will absorb water from the atmosphere. This degrades the fluid's performance, and if allowed to accumulate over a period of time, can drastically reduce its boiling point. Thus reducing the efficiency of the Braking System. Always service at recommended Intervals.
