Which brand of brake fluid is good?

Except for some specific models such as Mercedes-Benz, BMW, and other luxury vehicles that require specialized brake fluid, most vehicles can use general-purpose brake fluids from brands like Bosch and Ferodo. As long as the brake fluid is genuine, it is generally good, and car owners can choose on their own. It is important to select well-known brands or those recommended by the original manufacturer. Brake fluid brands: 1. Bosch: The Bosch brand, under Bosch Power Tools Co., Ltd., was founded in 1886 in Germany and is one of the largest industrial enterprises in Germany, enjoying very high recognition. In terms of product performance, it has an excellent reputation, not only for its highly reliable braking performance but also for its outstanding stability. Notably, Bosch's DOT4Plus (high-performance) brake fluid has very low viscosity, providing the most suitable and rapid braking response time for vehicles equipped with electronic braking systems (ABS, ESP, etc.). 2. Fuchs: Fuchs Petrolub SE, founded in 1931 in Germany, has grown over eighty years to become one of the world's largest independent lubricant manufacturers and the only German company specializing in lubricants with a global presence. With numerous lubrication experts and strong technical capabilities, it offers thousands of lubricant products to meet various application needs. Its brake fluid products can adapt to harsh working environments and also have long-lasting fluid protection capabilities. 3. Ferodo: Ferodo (FERODO), under the American Federal-Mogul Corporation, was established in 1897 and is one of the world's leading providers of braking solutions. Known as the "world leader in brake pads," it was the first company to manufacture brake linings and holds a significant position in the braking system industry. Naturally, its brake fluids also exhibit many excellent qualities, including good low-temperature performance, effective performance even in winter, and high corrosion resistance to protect components. 4. SINOPEC (Great Wall): Great Wall, a well-known Chinese brand of brake fluid, belongs to Sinopec Lubricant Company, established in 2002. It is one of China's largest high-end lubricant production and sales groups and the first to introduce the "Great Wall" brand in China's lubricant industry. With aerospace lubrication technology as its unique feature, it develops core aerospace lubrication technologies and is currently the only "Strategic Partner of China's Aerospace Industry." Great Wall's brake fluid is renowned for its high performance and long service life, making it popular among many consumers. 5. TEXTAR: The TEXTAR brand was founded in 1913 and is one of the brands under the TMD Friction Group. It is also a very large brand, with millions of products produced daily on TMD's production lines. With precise design and solid craftsmanship, it perfectly embodies German quality. As a UK-imported brake fluid, TEXTAR has always been highly favored by the public. With better formulations and high British standards, it offers excellent safety performance and superior corrosion resistance, consistently protecting the braking system.

I've been running a repair shop for years and change brake fluid every day. I recommend going with big brands like Bosch or Mobil's DOT4 type. This stuff is all about safety—don't skimp on it. Higher boiling point means it's less likely to vaporize and fail during high-speed braking. Brake fluid absorbs moisture and corrodes the system, so change it at least every two years regardless of what the manual says—safety first. I've seen plenty of cheap off-brand fluids cause accidents for customers, real lessons learned. DOT4 has wide compatibility and works for most vehicles; mixing different types can damage seals—don't even try it. Honestly, Bosch offers reliable quality with a boiling point dozens of degrees higher than standard, slightly pricier but worth it. Have it changed at a proper shop—DIY isn't easy to get right.

I've been driving for several years, always focusing on practicality and not overspending. For brake fluid, Shell or Castrol are both good options with high cost performance. Regular DOT3 is sufficient, but DOT4 is better with a higher boiling point and anti-boiling properties, and the price difference is only a few dozen yuan. It's generally recommended to change it every two years, or follow the mileage as stated in the manual. Don't stock up when buying new fluid, as it can deteriorate after opening. Last time I changed to Shell, a bottle cost just over sixty yuan, which is reliable and doesn't affect the budget. Regular maintenance can avoid major repairs, making it very cost-effective.

When it comes to brake fluid, I always ponder over the ingredients – DOT4 is the most commonly used, with high boiling point and low moisture absorption; DOT5 is synthetic but has poor compatibility, only suitable for specific vehicles. Recommended brands include Mobil or Ferodo, known for their excellent boiling point indicators. Never buy cheap products as they are chemically unstable and can corrode the pipelines. Normally, it should be replaced every two years, but if the boiling point test shows lower values, it should be replaced earlier.

Daily commuting safety is no trivial matter. Choose Shell or the OEM-recommended DOT4 brake fluid, which has an appropriate boiling point and resists aging. Replacing it every two years is quite reasonable. DIY replacement carries risks, so it's best to have it done by a professional shop. Don't forget to check the fluid level after replacement—excessive moisture can make the brakes sluggish. Big brands like Castrol offer reliable quality.

I care about the environment, so I also consider low toxicity when choosing brake fluid—Bosch's eco-friendly DOT4 or the upgraded DOT5.1, which has a high boiling point and less pollution. When replacing, recycle the old oil properly—don't pour it randomly, as it's toxic. Synthetic types last longer, reducing frequent replacements, which protects the environment and saves money. Stick to reliable brands like Mobil, and checking user reviews doesn’t hurt.
