TRW PFB425POL DOT 4 Brake Fluid - Premium Protection for Safer Stops

Purpose and Specifications

TRW PFB425POL is a premium DOT 4 brake fluid in a convenient 0.25-liter bottle, designed to deliver reliable braking performance in everyday driving and demanding conditions. This high-quality fluid from TRW resists boiling even under intense heat from hard braking, preventing dangerous brake fade where the pedal softens and stopping power drops. It flows smoothly in cold weather down to below -50°C, ensuring quick ABS and ESP response for shorter stopping distances and better control. With advanced additives, it fights corrosion, protects rubber seals, and absorbs moisture to maintain consistent performance over time.

• Key Benefits: Superior heat resistance for safe, firm braking; excellent cold-weather flow for fast system response; long-lasting protection against wear and corrosion.
• Ideal for passenger cars, vans, and light trucks with hydraulic brakes.
• Shelf life: Up to 5 years unopened when stored cool and dry.

When to Use / Replace?

Use TRW PFB425POL for routine brake fluid changes or top-ups in DOT 4-compatible systems. Replace every 2 years or 40,000 km to avoid moisture buildup that lowers boiling point and risks brake failure - check more often if you drive in humid areas or tow heavy loads. Operating temps: Handles everyday braking up to 150°C+ and peaks over 260°C dry for aggressive stops without vapor lock.

FAQ

Q: Is TRW PFB425POL safe for my ABS or ESP system?
A: Yes, its low viscosity ensures fast pressure changes in small ABS valves, perfect for modern stability control - even in freezing temps.

Q: How do I know when to flush my brake fluid?
A: Every 2 years or 40,000 km; test boiling point at a shop or watch for spongy pedal, dark color, or moisture contamination.

Q: Can I mix it with other DOT 4 fluids?
A: Yes, fully compatible, but for best results, flush the system completely with fresh TRW fluid during service.
