Brake fluid is primarily composed of glycol ether or mineral oil, depending on whether it is a glycol-based fluid (like DOT 3, DOT 4) or a mineral oil-based fluid (like DOT 5).
Out of the options you provided:
- **Is mostly just engine oil**: This is not correct. Brake fluid is not made from engine oil.
- **Is always blue**: This is not correct. Brake fluids can come in various colors, including clear, amber, or even blue, depending on the type and brand, but it's not always blue.
- **Has a high boiling point**: This is correct. Brake fluid is designed to have a high boiling point to withstand the heat generated during braking without boiling, which could lead to brake failure.
- **Lubricates transmission parts**: This is not correct. Brake fluid is specifically designed for braking systems and is not used for lubricating transmission parts.
Therefore, the correct statement is that brake fluid **has a high boiling point**.
