Brake fluids based on polyglycol ethers as basic components, polyglycols as lubricant components, inhibitors and antioxidants with a content of A) 10 to 40% by weight, based on the brake fluid of polyalkylene glycols in the form of uniform compounds or mixtures of compounds of the formula I HO [R - O] n - H, in which R is a 1,2-ethylene and / or 1,2-propylene radical, the number of propylene radicals predominating, based on the individual compound or the mixture, and n a number of 10 or more means, and wherein the average molecular weight is 500 to 3,000, and B) 0.1 to 3% by weight of a fatty acid known per se as a corrosion inhibitor. |
