Aztec Oils HYDRATEC DOT 4 BF

Yes, it is fully compatible with other DOT 3 and DOT 4 brake fluids. However, mixing will dilute its superior properties. For best performance, it's recommended to use it in a flushed and refilled system. Do not mix with mineral oil-based fluids or DOT 5 silicone fluids.

DOT 4 fluids, like HYDRATEC DOT 4 BF, have a higher boiling point than DOT 3 fluids. This is crucial for preventing vapor lock, especially during heavy braking or in hot conditions. DOT 4 also generally offers better resistance to water absorption.

Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere. This lowers its boiling point and can cause corrosion. It is generally recommended to change brake fluid every 2-3 years or as specified by your vehicle manufacturer's service schedule.

The Dry Boiling Point (>230°C) is the boiling point of new, uncontaminated fluid. The Wet Boiling Point (>155°C) is the boiling point after the fluid has absorbed a certain amount of water (typically 3.7%). The Wet Boiling Point is a critical indicator of performance over time as fluid ages and absorbs moisture.

Yes, if your motorcycle requires DOT 3 or DOT 4 brake fluid, the HYDRATEC DOT 4 BF is suitable for both its braking and clutch systems.

The Kinematic Viscosity at -40°C is 1207 mm²/s. This ensures proper fluid flow and performance in cold weather conditions for most applications.

Yes, its high boiling point and resistance to heat make it well-suited for demanding driving conditions where brake performance is critical.

This often indicates the presence of air in the brake lines. Bleed the brake system thoroughly according to the vehicle manufacturer's instructions. If the problem persists, check for leaks in the brake lines or consider the possibility of the fluid boiling (though less likely with this high-boiling-point fluid unless severely overheated).

Check the brake fluid level in the reservoir. If low, top it up and check for leaks in the system. The light can also indicate worn brake pads or a fault in the ABS system, requiring further inspection.

Ensure the clutch fluid reservoir is at the correct level and the system has been properly bled. Contaminated or old fluid can affect clutch performance. If the issue persists, the clutch hydraulic system may require professional inspection.

This can indicate contamination, often by water or other substances. Drain and flush the entire brake system and refill with fresh HYDRATEC DOT 4 BF. Regular fluid changes are essential to prevent this.
