Product Information
Full details
The Carlube DOT 5.1 Brake Fluid is a high-quality hydraulic brake fluid designed for automotive applications, particularly vehicles equipped with ABS systems. It offers superior performance by resisting moisture absorption, thereby maintaining a high boiling point and preventing vapor lock. A key benefit is its enhanced corrosion protection for metal components and compatibility with seals, ensuring longevity. However, it is crucial to note that this fluid is not suitable for mineral oil brake and suspension systems found in certain classic vehicles.

FAQs
What does 'DOT 5.1' mean?
DOT 5.1 refers to a specific standard set by the US Department of Transportation for brake fluid performance, indicating a higher boiling point and better moisture resistance compared to older DOT 3 and DOT 4 fluids.
Can I mix Carlube DOT 5.1 with DOT 4 fluid?
While DOT 5.1 is glycol-based like DOT 3 and DOT 4, it is generally recommended not to mix different brake fluid types to maintain optimal performance. Always use the type specified by your vehicle manufacturer.
Why is moisture resistance important in brake fluid?
Brake fluid is hygroscopic (absorbs moisture). Absorbed water lowers the boiling point, increasing the risk of vapor lock, and can cause corrosion within the brake system. DOT 5.1 is formulated to resist this moisture pickup better than older standards.
How often should brake fluid be replaced?
Consult your vehicle's owner's manual. Typically, brake fluid should be replaced every 2-3 years, or as per the manufacturer's recommendation, to ensure optimal performance and safety.
What should I do if I spill brake fluid on my car's paint?
Immediately wash the affected area with plenty of water. Brake fluid can damage car paint.
Is this fluid suitable for power steering systems?
No, this is specifically a brake and clutch fluid. It should not be used in power steering systems, which require different types of hydraulic fluid.
Can I use this fluid in my classic car?
Only if your classic car's manual specifies DOT 5.1 fluid. It is NOT suitable for older systems that use mineral oil-based brake fluid.
Troubleshooting
Brake pedal feels spongy
This could indicate air in the brake lines or a low boiling point due to moisture contamination. Ensure the system is properly bled and consider replacing the fluid if it's old or has been exposed to the atmosphere.
Braking performance seems reduced, especially after heavy use
This may be due to vapor lock, indicating the brake fluid has reached its boiling point. Ensure you are using a fluid with an adequate boiling point (like DOT 5.1) and that it has not been contaminated. Check for leaks in the system.
Corrosion observed inside brake components
While Carlube DOT 5.1 offers corrosion protection, severe or accelerated corrosion could indicate prolonged exposure to water or the use of an incompatible fluid. Ensure regular fluid changes.
Pros and Cons
Pros
- Meets rigorous DOT 5.1 and ISO 4925 Class 5-1 standards.
- Excellent resistance to moisture pickup, maintaining high boiling point.
- Prevents vapor lock under demanding conditions.
- Protects metal components from corrosion.
- Compatible with essential brake system seals.
- Suitable for modern ABS systems.
Cons
- Must not be used in mineral oil brake systems.
- Can damage vehicle paintwork if spilled.
- Requires careful handling during application.
Setup, Compatibility & Care
Setup: Brake fluid replacement should be performed according to your vehicle manufacturer's service schedule or when the fluid is contaminated. It typically involves bleeding the brake system to remove old fluid and air, then refilling with new Carlube DOT 5.1 fluid.
Compatibility: This fluid is compatible with most standard automotive rubber seals and is ideal for vehicles with ABS. Crucially, it is NOT suitable for vehicles with mineral oil-based brake and suspension systems (e.g., some older Citroen, Jaguar, and Rolls Royce models). Always verify your vehicle's requirement before use.
Care: Brake fluid can be corrosive to vehicle paintwork. Any spills on painted surfaces must be immediately washed off with plenty of water. Store the fluid in a tightly sealed container in a cool, dry place.
