TERZO Brake Fluid DOT5.1—Redefining the Limits of Braking Safety
With 20 years in the lubricants industry, I’ve always believed: The performance of brake fluid directly determines control in life-or-death moments. As the flagship product of TERZO Brake Fluid series, DOT5.1 embodies our relentless pursuit of “safety redundancy.”
Why It’s Trusted:
→ 275°C Dry Boiling Point: Even after 10 consecutive hard brakes on the track, fluid temperature peaks below 200°C, eliminating vapor lock risks.
→ -40°C Silk-Smooth Flow: With a low-temperature viscosity of 850 mm²/s, response speed outperforms conventional DOT4 by 35%, delivering instant stops in extreme cold.
→ Dual Protection for Metal & Rubber: Copper strip corrosion rate <0.1mg/cm² (ASTM D130), tripling the lifespan of rubber seals.
The Numbers Don’t Lie: TERZO lab tests confirm that after 100 consecutive 100km/h→0 emergency stops, pedal travel deviation remains ≤1.2mm, with near-zero performance degradation.
Performance Comparison: About TERZO DOT5.1 vs DOT4
| Parameter | TERZO DOT5.1 | DOT4 Standard | Improvement |
|---|---|---|---|
| Dry Boiling Point (°C) | 275 | ≥230 | +19.6% |
| Wet Boiling Point (°C) | 185 | ≥155 | +19.4% |
| Kinematic Viscosity (-40°C, mm²/s) | 850 | ≤1,800 | 52% Reduction |
| Rubber Compatibility | Passes SWR Test | Basic Requirement | Zero Swelling |
