    • PURPOSE: Provided is a brake liquid composition for cars which uses specific boron esters compound to improve a boiling point, a wet boiling point and so on compared to the existed brake so that it reduces car accidents by vapor lock in a brake system. CONSTITUTION: In the brake liquid composition for the cars which includes solvent, ointment, viscosity adjusting agent and additive, the brake liquid composition for the cars is characterized by comprising 20-90wt% of boron esters compound which are more than one species among boron ester compounds shown in a chemical formula(I) and (II). In the chemical formula(I), R1 is an alkyl group with 1-3 carbons and n+m is an integer from 2 to 5. In the chemical formula(II), R2 is an alkyl group with 1-4 carbons and X and Y is an integer from 2 to 4.
