Product Number: 84232
Brake fluid must withstand extreme heat under heavy braking and resist moisture absorption that lowers boiling point over time. BG DOT 4 Brake Fluid (84232, 946ml) provides high-temperature protection, moisture resistance and lubricity. BG actual dry boiling point: 260°C (500°F) against the DOT 4 minimum of 230°C. BG actual wet ERBP: 166°C (330°F) against the DOT 4 minimum of 155°C. Compliant with FMVSS 116 (DOT 4) and SAE J1704. Suitable for ABS and clutch hydraulic systems.
BG DOT 4 meets the minimum dry equilibrium reflux boiling point (ERBP) of 230°C and wet ERBP of 155°C as defined by the specification, ensuring reliable braking performance before and after moisture absorption over the fluid's service life. Brake fluid absorbs moisture over time, which lowers its boiling point — regular replacement with high-quality DOT 4 maintains braking system reliability and prevents brake fade under hard use.
Compatible with all brake and clutch systems specifying DOT 4 fluid. The 946ml size is suited to workshops performing multiple brake fluid changes. Follow vehicle manufacturer's recommended change intervals.
DOT 4 fluid is compatible with DOT 3 systems and provides a higher boiling point. Please confirm with your vehicle manufacturer's recommendations.
The No. 1 fuel system cleaner among automotive professionals.

A. A high-performance glycol-ether DOT 4 brake fluid that meets or exceeds FMVSS 116 DOT 3 and DOT 4 specifications. Minimum 230°C dry boiling point — exceeds DOT 4 minimum requirement.
A. Where the vehicle manufacturer specifies DOT 4 — the most common UK passenger-car specification. Check vehicle handbook to confirm before fluid change.
A. Yes. All three are glycol-ether based and fully cross-compatible. WARNING: DOT 5 (silicone-based) is a different chemistry and is NOT compatible — do not confuse DOT 5 with DOT 5.1.
A. Most manufacturers specify brake fluid replacement every 2 years regardless of mileage. Brake fluid is hygroscopic — it absorbs water, which lowers boiling point and causes corrosion in the brake system.
A. Yes. BG DOT 4 is fully compatible with modern brake systems including ABS, ESP, traction control and electronic brake assistance.
A. For most passenger-car brake systems, 946ml is sufficient for a full brake fluid flush. For larger commercial vehicles or motorcycles, plan for additional fluid.
A. DOT 5.1 offers higher boiling point — useful for towing, performance driving, or sustained heavy braking. For normal road use, DOT 4 fully meets requirements. Both are interchangeable in DOT 4 systems.
A. Yes — WhatsApp us on 07754 288583 with any questions about specifications, suitability, or compatibility.
