Brake fluid brands include PFC, Bosch, BREMBO, Ferodo, etc. Below is relevant information about brake fluid: Overview: Automotive brake fluid, also known as hydraulic brake fluid, is a liquid used in the vehicle's braking system to transmit pressure and is a crucial product related to traffic safety. Brake fluid, made from refined diesel fractions with thickeners and antioxidants, comes in three types: hydraulic brake fluid, alcohol-based brake fluid, and synthetic brake fluid. Working Principle: The working pressure of brake fluid is generally 2MPa. All liquids have the characteristic of being incompressible. In a sealed container or a pipeline filled with liquid, when pressure is applied to the liquid, it quickly and uniformly transmits the pressure to all parts of the liquid. Hydraulic braking operates based on this principle. 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.

When it comes to brake fluid brands, I've researched quite a few during car maintenance. The Bosch DOT 4 stands out for its stable performance and quick brake response. Castrol's brake fluid is also widely used, offering good value for money and suiting daily driving needs. The Shell Helix series enjoys a solid reputation, especially for safe cold starts. Then there's Motul's high-end products, which are track-grade and deliver exceptional handling. Brands like Valvoline and Prestone are popular among American car enthusiasts for their extended change intervals. I recommend sticking with DOT 4 specification for better compatibility and avoiding cheap off-brands that can compromise braking distance and reliability. Additionally, checking the fluid quality every two years helps prevent deterioration and potential leakage issues.

As a seasoned driver with years of experience, I've used several types of brake fluid. Bosch is reliable, safe, and durable; Castrol is economical and practical; Motul is professional-grade, suitable for mountain driving; and there are high-performance types from ATE and Pentosin, which offer excellent sealing properties. Personally, I recommend focusing on corrosion resistance and low-temperature fluidity, especially in winter, as frozen fluid can lead to brake failure. When changing the fluid, ensure it matches your vehicle model—don’t just opt for the cheapest brands. Bosch or Prestone’s DOT 3 or higher are solid choices. It’s advisable to replace the brake fluid every 30,000 to 40,000 kilometers.

Car enthusiasts are well-versed in brake fluid brands. Bosch leads globally, covering all types of vehicles; Castrol's track edition is fantastic; Motul offers high-standard Japanese products; Brembo provides great supporting accessories; and Valvoline is known for its high durability. The core is the DOT grading system, with DOT 4 offering strong water resistance to avoid bubble risks. When choosing, prioritize big brands and avoid products from unknown manufacturers, as they can affect the lifespan of the brake system and overall driving safety.
