摘要

Brake fluids comprising a mixture of (a) an alkylene glycol and/or a polyalkylene glycol and/or an ether thereof, and (b) a corrosion inhibitor which is a C8- 18 primary aliphatic straight- or branched-chain amine and/or an salt of such an amine or condensate with an aliphatic carboxylic acid. Condensates with ethylene oxide, propylene oxide and butylene oxide are exemplified. Exemplified compositions also contain an alkylene oxide polymer as a lubricant, and in some cases a boric acid ester of tri-isopropanolamine.
