ABSTRACT:
Brake fluids of good quality which increase wet equilibrium reflux boiling point without increasing rubber swelling property and disperse or dissolve homogeneously the additives and metals extracted from rubber brake cups and cylinder pipes can be obtained by dissolving semipolar borates containing a bond represented by the formula, ##STR1## which can be a hybridized orbital between SP.sup.2 and SP.sup.3 with regard to boron atom and having at least two hydroxyl groups outside said bond and heteroborates comprising an SP.sup.2 hybridized orbital and containing butyl group and methyl group in their molecule in polyalkylene glycol monoalkyl ethers comprising a C.sub.1 -C.sub.4 alkyl group.
