Maintain reliable braking performance with Penrite Super DOT 4 Brake Fluid, a premium full synthetic brake fluid designed for use in a wide range of brake and clutch hydraulic systems. Formulated with a high boiling point, it helps deliver excellent braking response, consistent performance and dependable operation under demanding driving conditions.

Over time, brake fluid absorbs moisture from the air, which lowers its boiling point and can reduce braking performance under heavy braking. Penrite Super DOT 4 features a high dry boiling point of 275°C and a typical wet boiling point of 183°C, helping maintain effective braking performance and resist vapour formation across a wide operating temperature range. Its advanced formulation also provides compatibility with common brake system materials, making it suitable for a broad range of vehicle applications.

It’s suitable for passenger cars, 4WDs, motorcycles, light and heavy commercial vehicles, mining equipment, construction machinery and agricultural equipment requiring non-petroleum-based DOT 3, DOT 4 or Super DOT 4 brake fluid.

Directions

• Check the vehicle manufacturer's handbook to confirm the required brake fluid specification.
• Use only in brake or clutch hydraulic systems designed for compatible DOT 3, DOT 4 or Super DOT 4 fluid.
• For best results, flush the system with Penrite Super DOT 4 Brake Fluid before first filling or refilling.
• Replace brake fluid according to the vehicle manufacturer's recommended service intervals.
• Keep the container tightly sealed after opening to help prevent moisture contamination.
• Avoid contact with vehicle paintwork, varnish and skin. If skin contact occurs, wash thoroughly with water.

Important: Do NOT mix with silicone DOT 5 or mineral-based brake fluids. Vehicles requiring mineral-based hydraulic fluid, should use the specified fluid where appropriate.

Suitable For

• Passenger cars
• 4WDs and SUVs
• Motorcycles
• Light and heavy commercial vehicles
• Mining and construction equipment
• Agricultural machinery
• Compatible brake and clutch hydraulic systems requiring DOT 3, DOT 4 or Super DOT 4 brake fluid

This is a multi-application brake fluid and is not vehicle-specific. Always confirm the manufacturer's required specification before use.

Common Signs You May Need to Replace Your Brake Fluid

• Brake fluid has reached the manufacturer's recommended replacement interval
• Brake fluid appears dark or contaminated
• Reduced braking performance under demanding conditions
• A soft or spongy brake pedal
• Brake fluid has absorbed moisture over time
• The vehicle's maintenance schedule calls for a brake fluid flush
• Brake system servicing requires fresh fluid
• The brake fluid service history is unknown

Using Penrite Super DOT 4 Brake Fluid helps maintain reliable braking performance, supports consistent hydraulic operation and protects compatible brake system components. Regular brake fluid maintenance is essential for safe and dependable braking.
