MOTUL Brake Fluid - 9040/2

DOT 4 is an international performance standard for brake fluid. It specifies minimum dry (230°C) and wet (155°C) boiling points. MOTUL 9040/2 exceeds these minimums, offering enhanced safety and performance, especially under severe conditions.

Most vehicle manufacturers recommend changing brake fluid every 1 to 2 years, or after a specific mileage, typically 20,000-40,000 miles. This is because brake fluid absorbs moisture over time, which degrades its performance and can lead to brake system corrosion.

While DOT 4 fluids are generally compatible with other DOT 4 fluids, it is always recommended to use the same type and brand to maintain optimal performance characteristics. For best results, a complete system flush with MOTUL 9040/2 is advised when switching fluid types or brands.

Yes, absolutely. Its adherence to the ISO 4925 Class 6 standard means it has a low viscosity, which is specifically designed to work efficiently with modern electronic braking systems like ABS, ESP, and ASR, especially at low temperatures.

Brake fluid can damage painted surfaces. If a spill occurs, immediately wipe it off with a clean, damp cloth and rinse the affected area thoroughly with water. Avoid rubbing aggressively, which could spread the fluid and cause more damage.

The amount of fluid required for a full flush varies by vehicle model. A 1-liter bottle is often sufficient for many passenger cars, but larger vehicles or those with more complex brake systems might require slightly more. Always consult your vehicle's service manual for exact capacities.

While many motorcycles use DOT 4 brake fluid, it's crucial to check your specific motorcycle's owner's manual to confirm the recommended brake fluid type. Using the wrong fluid can lead to severe braking system failure.

This usually indicates air trapped in the brake lines. Re-bleed the entire brake system carefully, ensuring all air is expelled, starting from the caliper furthest from the master cylinder.

A rapid drop suggests an internal leak, possibly in the master cylinder or a subtle external leak not immediately visible. Inspect all brake components (lines, calipers, master cylinder) thoroughly for leaks. Seek professional inspection if unsure.

This could be due to old fluid that has absorbed too much moisture, leading to a lowered boiling point. Replace the brake fluid with fresh MOTUL 9040/2. If the problem persists, inspect brake pads, rotors, and calipers for wear or malfunction.

After working on the brake system, some vehicles may require a sensor reset or specific diagnostic procedure. Ensure all connections are secure. If the message persists, a diagnostic scan by a qualified technician may be needed to pinpoint the exact issue.
