Remsa DOT 4 Brake Fluid — Reliable Performance & Safety for Modern Brake Systems
Remsa DOT 4 Brake Fluid is engineered to deliver dependable braking performance, high thermal stability, and long‑term protection for hydraulic brake and clutch systems. Formulated to exceed SAE J1703 and ISO 4925 specifications, it ensures consistent braking response and enhanced safety across a wide range of driving conditions.
- Purpose & Compatibility
Suitable for All DOT 4‑Specified Systems
Remsa DOT 4 is recommended for:
- Hydraulic brake systems
- Hydraulic clutch systems
- Vehicles requiring a non‑petroleum, glycol‑based fluid
It is compatible with all DOT 3 and DOT 4 systems and can be used in both disc and drum brake configurations.
Meets and Exceeds International Standards
- SAE J1703
- ISO 4925 Class 4
These certifications ensure reliable performance in demanding thermal and mechanical environments.
- Thermal Stability & Vapour Lock Resistance
High Dry Boiling Point
- Minimum Dry Boiling Point: 260°C
This elevated boiling point helps prevent vapour lock — a dangerous condition where brake fluid boils, forming compressible vapour bubbles that reduce braking effectiveness.
Moisture Absorption Awareness
Brake fluid naturally absorbs moisture through brake hoses and seals. Over time, this lowers the boiling point and increases the risk of:
- Spongy pedal feel
- Reduced braking efficiency
- Brake fade under heavy use
Remsa DOT 4 is formulated to maintain stable performance even as moisture accumulates.
- Chemical Protection & System Longevity
Corrosion Protection
Remsa DOT 4 contains anti‑corrosion additives that protect:
- Master cylinder components
- Wheel cylinders
- ABS modulators
- Steel and aluminum brake lines
This helps prevent internal rust, pitting, and premature component wear.
Oxidation Resistance
The fluid maintains its chemical integrity over time, reducing degradation caused by heat cycles and moisture exposure.
- Maintenance Recommendations
Replace Every 2 Years
To maintain maximum braking performance and safety, Remsa recommends replacing DOT 4 brake fluid every 24 months, or sooner under:
- High‑humidity climates
- Frequent heavy braking
- Mountain or high‑temperature driving
Signs of Fluid Degradation
- Dark or cloudy fluid
- Spongy brake pedal
- Reduced braking response
- Increased stopping distance
Regular replacement helps prevent vapour lock and protects rubber seals from corrosion.
- Key Technical Parameters
- Dry Boiling Point: ≥ 260°C
- Viscosity at –40°C: compliant with ISO 4925 Class 4 requirements
These characteristics ensure reliable performance in both high‑temperature braking and cold‑weather operation.
- Recommended Applications
- Passenger cars
- Light commercial vehicles
- Vehicles with disc or drum brakes
- Hydraulic clutch systems
- Drivers seeking a safe, reliable DOT 4 solution
