What is DOT 4 Brake Fluid
DOT 4 brake fluid is a glycol-ether and borate ester-based hydraulic fluid used in the braking and clutch systems of modern passenger vehicles, performance cars, SUVs, and commercial vehicles. It is the globally dominant brake fluid grade for modern vehicle platforms, specified across European, Japanese, Korean, and American OEM vehicles as the standard brake fluid for systems equipped with ABS, Electronic Stability Control (ESC), Electronic Stability Programme (ESP), traction control, and other advanced braking technologies.
The DOT 4 classification is governed by Federal Motor Vehicle Safety Standard No. 116 (FMVSS 116), which mandates a minimum dry boiling point of 230°C (446°F) and a minimum wet boiling point of 155°C (311°F) — significantly higher thresholds than DOT 3, making DOT 4 the appropriate choice for vehicles subject to higher braking loads, more frequent braking cycles, and more demanding operating conditions.
The incorporation of borate ester compounds in DOT 4 formulations is what delivers this superior thermal performance. Borate esters provide a higher boiling point ceiling than the glycol-ether base alone, while also offering improved corrosion protection for the aluminium, steel, brass, and copper components found in modern multi-circuit brake systems.

Exsan DOT 4 Brake Fluid — Technical Specifications
Exsan’s DOT 4 brake fluid is a precision-engineered borate ester and glycol-ether formulation that exceeds the requirements of FMVSS 116 DOT 4, ISO 4925 Class 4, SAE J1704, and JIS K2233.
Chemical Base
Polyethylene glycol ethers and borate esters with a balanced additive package delivering superior corrosion inhibition, pH stability, and full compatibility with both natural and synthetic rubber brake system components.
Dry Boiling Point
Exceeds the FMVSS 116 DOT 4 minimum of 230°C (446°F) — providing a significantly higher thermal safety margin than DOT 3 for vehicles operating under heavier braking loads.
Wet Boiling Point
Exceeds the FMVSS 116 DOT 4 minimum of 155°C (311°F) — ensuring safe and predictable braking performance even after moisture absorption during extended service intervals.
Kinematic Viscosity
Meets the maximum viscosity limit of 1,800 mm²/s at −40°C per FMVSS 116 — ensuring reliable cold-weather brake pedal response across all operating climates.
pH Range
Maintained between 7.0 and 11.5 per FMVSS 116 — protecting all metal brake system components from corrosion across the full service life of the fluid.
Fluid Colour
Colourless to amber — per DOT 4 standard classification under FMVSS 116.
Compatibility
Fully miscible and compatible with all DOT 3 and DOT 4 approved brake fluids, ABS systems, disc and drum brakes, and both natural and synthetic rubber brake components including hoses, master cylinder seals, and wheel cylinder cups. Not compatible with mineral oil-based LHM fluids or silicone-based DOT 5 fluids.
Vehicle Applications for Exsan DOT 4 Brake Fluid
Modern Passenger Vehicles
The OEM-specified brake fluid grade for the vast majority of passenger vehicles manufactured from the late 1990s onwards across European, Japanese, Korean, and American platforms — including Audi, BMW, Mercedes-Benz, Volkswagen, Toyota, Honda, Hyundai, and Ford.
Vehicles with ABS, ESC, and ESP Systems
DOT 4’s superior boiling point and thermal stability make it the recommended grade for vehicles equipped with Anti-lock Braking Systems (ABS), Electronic Stability Control (ESC), Electronic Stability Programme (ESP), and Acceleration Slip Regulation (ASR) — all of which generate additional heat in the brake circuit during automated braking interventions.
Performance and Sports Vehicles
Higher thermal demands from track use, aggressive driving, and repeated heavy braking make DOT 4 the preferred grade for performance vehicle applications where DOT 3 may not provide sufficient boiling point margin.
SUVs and 4WD Vehicles
High vehicle weight combined with frequent braking on steep terrain generates sustained brake heat — making DOT 4’s superior wet boiling point critical for maintaining reliable braking performance in off-road and loaded towing conditions.
Light and Medium Commercial Vehicles
Delivery vans, minibuses, and light commercial vehicles operating in urban stop-start environments with frequent braking cycles benefit from DOT 4’s higher thermal ceiling and extended service interval compared to DOT 3.
Clutch Systems
DOT 4 is widely used as a hydraulic clutch fluid in vehicles with hydraulically operated clutch systems — particularly across European OEM platforms where a shared brake and clutch fluid reservoir is standard.
Why Distributors Source DOT 4 Brake Fluid from Exsan
20+ Years of Error-Free DOT 4 Production
Every batch of DOT 4 brake fluid produced at Exsan’s Ankleshwar facility undergoes daily quality evaluation by an in-house team of chemical engineers and chemists. The result is a verified 20+ year track record of error-free production — a standard that procurement teams across 50+ countries trust for their most demanding vehicle platforms.
Formulated to Exceed FMVSS 116 DOT 4 Minimums
Exsan’s DOT 4 formulation is engineered to exceed — not merely meet — the minimum boiling point thresholds set by FMVSS 116 and SAE J1704. This philosophy ensures consistent performance throughout the fluid’s service life, not just at the point of manufacture.
100% Pure Virgin Borate Ester and Glycol-Ether Additives
Every batch of Exsan DOT 4 is produced using 100% pure virgin borate ester and glycol-ether base stocks sourced exclusively from Europe, the USA, or India — never recycled, never second-quality, never from China. Three-year control batch retention ensures complete traceability on every consignment shipped worldwide.
DOT 4 LV — Low Viscosity Variant Available
In addition to standard DOT 4, Exsan manufactures DOT 4 LV (Low Viscosity) — specifically engineered for vehicles with ESP, ESC, and other advanced active braking systems requiring faster fluid response through complex hydraulic circuits. DOT 4 LV delivers the same superior boiling point as DOT 4 with a significantly lower kinematic viscosity at low temperatures.

Frequently Asked Questions
What is DOT 4 brake fluid used for?
DOT 4 brake fluid is used in the hydraulic braking and clutch systems of modern passenger vehicles, SUVs, performance cars, and light commercial vehicles. It is the OEM-specified grade for most vehicles manufactured from the late 1990s onwards, particularly those equipped with ABS, ESP, and electronic traction control systems.
What is the difference between DOT 3 and DOT 4 brake fluid?
DOT 4 has a higher minimum dry boiling point of 230°C versus 205°C for DOT 3, and a higher minimum wet boiling point of 155°C versus 140°C for DOT 3. DOT 4’s borate ester formulation delivers superior thermal performance for modern vehicles with advanced braking systems. DOT 4 can be used in systems specifying DOT 3, but DOT 3 should not be used where DOT 4 is required.
What is the difference between DOT 4 and DOT 4 LV?
DOT 4 LV (Low Viscosity) meets the same boiling point requirements as standard DOT 4 but is formulated to a significantly lower kinematic viscosity at low temperatures — making it specifically suited to vehicles with ESP, ESC, and high-frequency ABS systems that require rapid fluid response through complex brake circuits.
Is Exsan DOT 4 brake fluid compatible with DOT 3?
Yes. Exsan’s DOT 4 formulation is fully miscible and compatible with all DOT 3 and DOT 4 approved brake fluids. It is not compatible with mineral oil-based LHM fluids or silicone-based DOT 5 fluids.
Does Exsan offer private label DOT 4 brake fluid manufacturing?
Yes. Exsan provides full OEM and private label DOT 4 production including custom packaging design and branded labelling. A minimum single 40FT FCL can be produced and shipped to any global market.
What packaging is available for DOT 4 brake fluid?
Exsan offers 200+ packaging variations for DOT 4 including 100ml, 250ml, 500ml, 1 litre, 5 litre, and bulk drum formats in both metal and plastic. Metal cans include a patented Plasma Polyamide rust-proof treatment guaranteed for 24 months.
How often should DOT 4 brake fluid be replaced?
Most vehicle manufacturers recommend replacing DOT 4 brake fluid every 2 years regardless of mileage, as the fluid gradually absorbs atmospheric moisture which lowers its boiling point over time. Vehicles operating in demanding conditions — frequent towing, track use, or mountain driving — may require more frequent replacement intervals.
