Purpose and Specifications

The TRW PFB405CE is a DOT 4 synthetic brake fluid designed for modern vehicles with advanced braking systems, including ABS and electronic stability control (ESP). This 5-litre canister delivers reliable hydraulic pressure transfer from your brake pedal to the wheels, ensuring consistent stopping power in all driving conditions.

Key performance features include a dry boiling point of 260°C, which means your brakes maintain full effectiveness even under extreme heat from repeated braking. The fluid works safely across temperatures from -50°C to +50°C, making it suitable for both cold winters and hot summer driving. TRW formulates this fluid with advanced additives that reduce corrosion inside brake lines and cylinders, protecting your entire braking system from rust and wear.

This fluid is fully compatible with all vehicles requiring DOT 4 specification, including those with disc brakes on the front and drum brakes on the rear, as well as modern all-disc brake systems.

When to Use and Replace?

Replacement Schedule: TRW recommends changing your brake fluid at least every 2 years, regardless of mileage. Brake fluid absorbs moisture from the air over time, which gradually lowers its boiling point and reduces braking performance. Annual replacement is recommended if your vehicle uses older DOT 3 fluid.

Signs You Need New Fluid:

• Soft or spongy brake pedal feel
• Brake warning light on your dashboard
• Reduced braking responsiveness or longer stopping distances
• Visible corrosion or discolouration inside brake components

Always follow your vehicle manufacturer's maintenance schedule, as some modern vehicles may require more frequent changes. This 5-litre container provides enough fluid for multiple brake system flushes on most passenger cars.

Frequently Asked Questions

Q: Can I mix TRW DOT 4 with other brake fluids?
A: Yes. TRW DOT 4 safely mixes with all other DOT 3, DOT 4, and DOT 5.1 fluids that meet international standards. However, for best results, completely flush your system with new TRW fluid rather than topping up old fluid.

Q: Why does brake fluid need changing if I don't use much of it?
A: Brake fluid absorbs moisture from humidity in the air through microscopic pores in rubber seals and hoses. This moisture lowers the boiling point over time, reducing safety. Even a parked car loses braking performance after 2 years.

Q: Is this fluid suitable for my car with ESP or ABS?
A: Yes. TRW DOT 4 is specifically formulated to work with electronic stability programmes and ABS systems. It reacts quickly enough to support these safety technologies, even in emergency braking situations.
