A brake fluid comprises a) from 10 to 50, preferably from 20 to 40, % by weight of diethylene glycol and/or dipropylene glycol and b) from 50 to 90, preferably from 60 to 80, % by weight of one or more monoalkyl ethers of (poly)ethylene glycol and/or (poly)propylene glycol. The novel fluids are in particular free of borate and, owing to the low hygroscopicity, are suitable for use in regions of high relative humidity.
