What are the components of brake fluid?
1 Answers
There are three types of brake fluid: 1. Castor oil-alcohol type, which is made by blending 45% to 55% refined castor oil with 55% to 45% low-carbon alcohol (ethanol or butanol); 2. Synthetic type, which is made by mixing ethers, alcohols, esters, etc., with additives such as lubricants, antioxidants, rust inhibitors, and anti-rubber swelling agents; 3. Mineral oil type, which is made by adding thickeners and other additives to refined light diesel oil fractions. After being used for a certain period, brake fluid is prone to a decrease in boiling point, contamination, and varying degrees of oxidation and deterioration. Therefore, vehicles should regularly check the quality and performance of brake fluid based on climate, environmental conditions, seasonal changes, and working conditions, and replace it promptly. Under normal use, brake fluid should be replaced every 50,000 kilometers or two years.
