Racingline Brake Fluid 300 DOT 4 500ml

Racingline Brake Fluid 300 DOT 4 – 500ml (VWR69000BF1)

Whether you’re running standard factory brakes on the road or a serious big brake setup on track, Racingline’s Brake Fluid 300 DOT 4 is one of the simplest and most effective upgrades you can make to your braking system. It is a high specification racing fluid that performs just as well during everyday driving.

If you’ve ever pushed your car hard and felt the brake pedal go soft or spongy, you’ve likely experienced brake fade. This usually happens when standard brake fluid gets too hot and starts to boil, creating air bubbles in the brake lines. Switching to a higher specification fluid like this one should always be your first step before considering bigger upgrades such as performance pads or a big brake kit.

Why upgrade your brake fluid?

Brake fluid quality is measured largely by its boiling point. The higher the boiling point, the harder you can use your brakes before performance drops off. Racingline 300 DOT 4 offers one of the highest specifications available, giving you firmer, more consistent pedal feel even under repeated heavy braking.

• Dry boiling point: 312°C (594°F)
• Wet boiling point: 204°C (399°F)
• Highly refined Super DOT 4 formulation, exceeding many DOT 5.1 fluids
• Compatible with all brake setups, from factory systems through to Racingline Stage 3 Big Brake Kits
• Suitable for road, fast road and motorsport use without compromise
• Supplied in a sealed 500ml bottle

Important notes on use

Brake fluid is hygroscopic, meaning it absorbs moisture from the air over time. This moisture lowers the boiling point and reduces braking performance, which is why regular fluid changes are essential.

• Fully replace your brake fluid every 1 to 2 years for road use, and more often for hard driving or track days.
• Always store new fluid in a sealed container to prevent moisture absorption.
• Once opened, a bottle of brake fluid should not be re-used. This is why Racingline supplies the fluid in 500ml bottles, the ideal size for a single complete change.
• For correct performance, fully bleed and replace the existing fluid rather than topping up.
