Engineered for higher performance demands, STP Brake Fluid DOT 4 (500ml) delivers superior heat resistance and consistent braking performance under heavy load, towing, or mountainous driving. With an elevated boiling point that exceeds DOT 3 standards, this premium glycol-ether based fluid provides enhanced safety for modern ABS, ESP, and traction control systems while preventing corrosion in brake components.

Key Advantages vs. DOT 3:

✔ Higher Boiling Point – Better resistance to brake fade
✔ Improved Wet Performance – Maintains effectiveness even with moisture absorption
✔ Optimized for Modern Systems – Compatible with ABS/ESP electronics
✔ 500ml Bottle – Ideal for complete fluid flushes

Technical Specifications:

• Dry Boiling Point: ≥230°C (446°F)

• Wet Boiling Point: ≥155°C (311°F)

• Viscosity: Meets ISO 4925 Class 4 standards

• Base: Glycol Ether (Non-silicone)

Recommended For:

• Performance street vehicles

• Cars frequently driven in mountainous areas

• Vehicles used for towing trailers

• European/Asian models requiring DOT 4

• Preventive maintenance (every 2 years)

How to Use:

1. Clean Reservoir – Wipe master cylinder opening

2. Full System Flush – Replace all old fluid (not just reservoir)

3. Bleed Properly – Follow manufacturer’s sequence

4. Disposal – Collect old fluid for recycling

Pro Tips:

 Track Day Prep – Upgrade from DOT 3 for harder braking
Moisture Test – Use test strips annually
Storage – Keep tightly sealed (absorbs moisture from air)
Not for DOT 5 Systems – Incompatible with silicone-based fluids
