Aztec Hydratec DOT 4 Brake Fluid Premium For SAE J1703 ISO 4925 FMVSS 116 1L

HYDRATEC DOT 4 BF – Synthetic Brake & Clutch Fluid

HYDRATEC DOT 4 BF is a high-quality synthetic brake and clutch fluid, specially formulated to provide reliable performance under extreme conditions. Designed for cars, commercial vehicles, and motorcycles requiring DOT 3 or DOT 4 fluids, it offers superior protection against corrosion, high temperatures, and vapour lock.

Applications

DOT 4 BF is suitable for all brake systems, particularly those exposed to extreme operating conditions. It is compatible with disc, drum, and ABS braking systems, as well as clutch systems.

Recommended by Aztec Oils as suitable for the following specifications:

• FMVSS 116 DOT 4

• ISO 4925 Class 4

• JIS K2233

• SAE J1703

• SAE J1704

Note: DOT 4 BF can be used in place of DOT 4 LV, although EPS effectiveness may be reduced in cold climates. It should not be used in systems designed for mineral oil-based fluids (e.g., LHM green fluids) or where Silicone DOT 5 fluid is required.

Key Benefits

• Fully compatible with other DOT 3 and DOT 4 brake fluids

• High boiling point ensures consistent brake performance under heavy braking

• Superior resistance to water absorption compared to DOT 3 fluids, reducing vapour lock risk

• Minimal rubber-component (seal) swell

• Reliable performance in clutch systems
