Abstract:
The present invention relates to a brake fluid composition comprising a glycol compound as a solvent, and triazole, thiadiazole mixture, and antioxidant as metallic corrosion inhibitors. Provided is a brake fluid composition having improved long-term metallic and high-temperature corrosion inhibition. The brake fluid composition according to the present invention significantly improves long-term durability by being a superior anti-corrosive as well as having a reduced weight variation on a test piece, and has a superior high-temperature corrosion inhibition while having negligible effects on the equilibrium reflux boiling point and the wet equilibrium reflux boiling point.
