Which brand of brake fluid is better?

[August]

Brake fluids from different brands each have their own advantages and disadvantages. The choice should be based on actual conditions to determine the appropriate type. Definition of brake fluid: Brake fluid, also known as hydraulic brake fluid or mineral oil brake fluid, is made from refined diesel fractions with thickeners and antioxidants. There are three types: mineral oil brake fluid, alcohol-based brake fluid, and synthetic brake fluid. Brake fluid is required to have good viscosity-temperature properties, enabling it to work over a wide and low temperature range, along with excellent oxidation stability, anti-foaming properties, resistance to rubber swelling, and rust prevention. Characteristics of brake fluid: Good viscosity-temperature properties and low freezing point, ensuring good fluidity at low temperatures; high boiling point, preventing vapor lock at high temperatures; minimal quality changes, avoiding corrosion and deterioration of metals and rubber. Precautions for using brake fluid: If gasoline, diesel engine oil, or windshield washer fluid is accidentally mixed into the brake fluid, it will affect braking performance and should be replaced promptly. If the vehicle experiences inconsistent braking during normal driving, the brake fluid should be replaced immediately. Before replacement, clean the braking system thoroughly with alcohol.

I've always believed safety is the top priority, and choosing brake fluid should never be taken lightly. Big brands like Castrol and Ate are truly excellent—they undergo rigorous testing, have high boiling points, and are less prone to failure under high temperatures, ensuring stable brake system performance and preventing failure accidents. Brake fluids are classified into DOT3 and DOT4 grades, with DOT4 generally recommended for most cars due to better compatibility. Even with a good brand, regular replacement is essential—check every two years or 40,000 kilometers. Don’t wait until the brakes feel spongy to act. I remember one time I had to brake hard in an emergency on the road, and it was all thanks to quality fluid that nothing went wrong. This stuff is directly tied to safety, so it’s worth spending money on reliable products.

As a parent who frequently drives to pick up kids, I value cost-effectiveness more. There's no need to blindly chase after premium brake fluids—Bosch or domestic brands like Kunlun are quite practical. These brands meet DOT4 standards, are affordably priced, and perform just as well as big-name products. When I changed the fluid, I realized that higher prices don't always mean better value—what matters are the certification marks and packaging dates. By the way, changing brake fluid is simple enough to DIY, and the tools are inexpensive. Just be careful not to mix different types of fluid, as it can corrode the lines. Overall, choosing the right brand can save you dozens of yuan—money better spent where it counts.

Back when I was into car modifications, brake fluid was the key to performance upgrades. Motul and Brembo were my top recommendations, with ultra-high boiling points perfect for repeated braking during aggressive driving. Compared to regular fluids, it minimizes bubble formation, delivering faster and more stable brake response. Tested it multiple times on the track – switching to high-performance fluid noticeably reduces braking distance. Though a bit pricey, it requires checking every six months. When chatting with fellow enthusiasts, we all agreed this investment is worth it – don't skimp on safety to save a few bucks.
