Bosch DOT 3 brake fluid provides high performance, safety, and reliability for hydraulic brake systems, exceeding international standards and offering protection against vapor lock, corrosion, and seal wear. It has a dry boiling point of 205°C and a wet boiling point of 140°C. It’s suitable for older vehicles and DIY maintenance, though it must be replaced over time due to its hygroscopic nature, which means it absorbs moisture, leading to reduced boiling points and potential system corrosion.
Key Features & Benefits
- High Performance: Offers consistent and steady brake pressure, especially in high-heat conditions.
- Protection: Safeguards against vapor lock, corrosion of internal components, and wear of seals and hoses.
- Lubrication: Contains additives that lubricate hydraulic system components, ensuring longevity and proper function.
- Corrosion Protection: Includes corrosion inhibitors to protect the system’s components.
- Standard Compliance: Exceeds international standards like FMVSS §571.116 DOT 3 and SAE J1703.
- Wide Compatibility: Suitable for various vehicles, including those with ABS, and is often used in older vehicle models.
- Amber Color: The fluid is amber, which helps with proper identification in the reservoir.
Technical Specifications
- Dry Boiling Point: 205°C
- Wet Boiling Point: 140°C
- Viscosity: High performance is maintained even under extreme temperature conditions.
Important Considerations
-
Moisture Absorption:
Brake fluid is hygroscopic (absorbs moisture) over time, which lowers its boiling point and can lead to internal corrosion.
-
Regular Checks & Replacement:
Brake fluid levels should be checked regularly, and the fluid should be replaced periodically to maintain system performance and safety.
-
Contamination:Do not mix with other standard brake fluids, like DOT 4, and check the vehicle’s owner’s manual for the correct type.
