Purpose and Specifications

A.B.S. 7507 is a DOT 5.1 brake fluid engineered for modern vehicles equipped with ABS (Anti-lock Braking System) technology. This glycol-based fluid delivers superior heat resistance and consistent braking performance across a wide range of driving conditions.

Key Performance Characteristics:

• Dry Boiling Point: 260°C (500°F) minimum – prevents brake fade during intense braking
• Wet Boiling Point: 180°C (356°F) minimum – maintains performance in humid conditions and after moisture absorption
• Low-Temperature Viscosity: Ensures responsive braking in freezing conditions down to -40°C (-40°F)
• ABS Compatibility: Formulated to work seamlessly with modern stability and anti-lock systems
• Corrosion Protection: Contains inhibitors to protect brake system components and extend service life

When to Use / Replace?

Replace your brake fluid every 2 years or 40,000 km, whichever comes first. DOT 5.1 fluid absorbs moisture from the air over time, which reduces its boiling point and increases corrosion risk. More frequent replacement is recommended if you:

• Drive in mountainous terrain or tow heavy loads regularly
• Use your vehicle for track days or high-performance driving
• Live in humid climates
• Notice a soft or spongy brake pedal

Always use fresh, sealed fluid from the original container. Once opened, use the entire bottle within one service session to prevent moisture contamination.

Frequently Asked Questions

Q: Can I mix A.B.S. 7507 DOT 5.1 with my current DOT 4 brake fluid?
A: Yes. Both DOT 4 and DOT 5.1 are glycol-based and fully compatible. However, mixing reduces the overall boiling point of the fluid, so it is best to perform a complete fluid flush and fill with fresh DOT 5.1 for optimal performance.

Q: Is DOT 5.1 the same as DOT 5?
A: No. DOT 5.1 is glycol-based, while DOT 5 is silicone-based. They are not compatible and should never be mixed. Always verify your brake fluid type before purchasing.

Q: How do I know if my vehicle needs DOT 5.1?
A: Check your vehicle's service manual or the brake fluid reservoir cap for the recommended DOT specification. Most modern vehicles with ABS systems benefit from DOT 5.1's higher boiling point, especially if you drive in demanding conditions.
