R-(OCnH2n)z-, -R''-OH, and -Rs(OH)s, where Rs is a polyvalent hydrocarbon radical having s number of hydroxyl groups, where s varies from 2 to 5, n is a whole number that varies from 2 to 4, and z varies from 1 to 4, where a varies from 1.11 to 2.02, b varies from 0.023 to 1.00 and the sum of a + b varies from 2.024 to 3.00. The present invention also comprises a brake fluid system using the above polysiloxane polymer as the brake fluid. WHERE R is a monovalent hydrocarbon radical or a halogenated monovalent hydrocarbon radical, R'' is a divalent hydrocarbon radical, E is selected from the group consisting of R-, ROR''-, A silicone polymer useful as brake fluid comprising a polymer of the structure, |
