Ravenol R325+ Racing Brake Fluid is a top-tier high-performance brake fluid designed for drivers who want exceptional braking consistency on fast road, performance, and enthusiast-driven vehicles. While originally developed with motorsport-level thermal stability, its real strength for road users is simple: it massively reduces brake fade, keeps the pedal firm for longer, and maintains performance where standard fluids quickly fall short.
Blended using advanced glycol ether/ester chemistry, R325+ offers outstanding heat resistance and long-term stability. With a 328°C dry boiling point, it provides far greater vapour lock resistance than typical DOT 4 fluids – ideal for modern turbocharged, heavy, or high-output cars that generate significant braking temperatures even during spirited road driving.
The enhanced lubricity additives also help protect brake system components, promoting smoother operation, cleaner ABS performance, and increased longevity of seals and moving parts.
This makes Ravenol R325+ a perfect upgrade for drivers who enjoy fast B-road runs, performance tuning, or simply want the most dependable brake pedal feel in all conditions.
Real-World Experience: Solving Ducati Rear Brake Fade
I use Ravenol R325+ personally in my Ducati Monster 1200 R, and it’s the only brake fluid that’s cured the infamous issue of rear brake fade that plagues modern Ducati models. Normally, the rear fluid would degrade every couple of weeks due to heat soak – but since switching to R325+, the rear brake stays firm, consistent, and reliable.
If you own a performance motorcycle or a car with brake systems prone to heat-related fade, this fluid makes a noticeable, real-world difference.
Why It’s Ideal for Fast Road & High-Performance Cars
- Handles high braking temperatures produced by heavy, turbocharged, or performance-focused vehicles
- Reduces brake fade during spirited driving or repeated hard stops
- Provides a consistently firm pedal feel
- Excellent for upgraded brake setups (big brake kits, performance pads/discs)
- Perfect for drivers who want race-level stability without needing a full motorsport fluid service schedule
Key Features
- Extremely high 328°C dry boiling point for superior fade resistance
- Stable, consistent performance in demanding real-world driving
- Excellent lubricity for longer component life
- Outstanding ABS response and system compatibility
- Low viscosity at cold temperatures for strong year-round performance
