Product Description
FUCHS MAINTAIN DOT 4 BRAKE FLUID is a premium high-performance glycol ether-based brake fluid specially developed for hydraulic brake systems, hydraulic clutch systems, passenger cars, commercial vehicles, motorcycles, light commercial vehicles, ABS, ESP, ASR, traction control systems, disc brakes, and drum brakes requiring FMVSS 116 DOT 4, SAE J1704, ISO 4925 Class 4, or JIS K2233 performance. Formulated with advanced corrosion inhibitors and oxidation stabilisers, it delivers excellent high-temperature braking performance, outstanding low-temperature fluidity, superior corrosion protection, excellent rubber compatibility, high wet and dry boiling points, and reliable braking performance under severe operating conditions.
Features and Benefits
High Boiling Point
Provides excellent resistance to vapour lock under severe braking conditions with high dry and wet boiling points for improved braking safety.
Excellent Low-Temperature Performance
Maintains excellent fluidity at very low temperatures, ensuring rapid brake response and proper ABS/ESP operation.
Outstanding Corrosion Protection
Advanced corrosion inhibitors protect steel, cast iron, aluminium, brass, copper, and other brake system components against rust and corrosion.
Excellent Oxidation Stability
Resists oxidation and thermal degradation, maintaining fluid performance over extended service intervals.
Excellent Seal Compatibility
Compatible with EPDM rubber seals, hoses, and other elastomers commonly used in hydraulic brake and clutch systems.
Reliable Brake Performance
Provides consistent hydraulic pressure transmission for smooth, responsive, and reliable braking performance under all driving conditions.

Compatibility
FUCHS MAINTAIN DOT 4 BRAKE FLUID is compatible with other DOT 4 and DOT 3 glycol ether-based brake fluids. It is not compatible with DOT 5 silicone-based brake fluids or LHM mineral hydraulic fluids. Always follow the vehicle manufacturer's recommendations and avoid contamination during servicing.
Handling & Storage
Store in tightly sealed original containers in a cool, dry place away from moisture. Brake fluid is hygroscopic and absorbs moisture from the atmosphere; therefore, containers should be opened only when required and resealed immediately after use.
Health & Safety
Refer to the latest Safety Data Sheet (SDS) for detailed information regarding safe handling, storage, transportation, personal protective equipment, and disposal.
