Product Information

Full details

The Wilwood EXP600 Plus DOT 4 Brake Fluid is designed for motorsports and high-performance road vehicles requiring extreme braking reliability. Its key benefit is maintaining a firm brake pedal under intense heat and pressure, even after repeated cycles. A potential caveat for casual users is its specialized nature, optimized for racing conditions rather than standard daily driving. This highly refined blend exceeds DOT and SAE specifications, offering exceptional performance in demanding environments.

FAQs

What is the difference between EXP600 Plus and standard DOT 4 fluid?

EXP600 Plus has significantly higher dry and wet boiling points (626°F dry / 417°F wet) compared to standard DOT 4 (typically 446°F dry / 311°F wet), making it far more resistant to brake fade under extreme heat.

Can I mix Wilwood EXP600 Plus with other DOT 4 fluids?

While it is technically possible, it is strongly advised against. Mixing can dilute its high-performance properties and compromise its exceptional boiling point. For best results, use it in a system flushed clean of all previous fluid.

How often should I change this brake fluid?

For daily driving, follow your vehicle manufacturer's recommendations. For track use or high-performance applications, it is recommended to flush and replace the fluid at least annually, or more frequently depending on the severity of use.

Is this fluid suitable for ABS systems?

Yes, Wilwood EXP600 Plus is a DOT 4 fluid and is generally compatible with ABS systems. However, always consult your vehicle's manual for specific fluid recommendations.

What does 'wet boiling point' mean?

The wet boiling point is the temperature at which the fluid will boil after it has absorbed a certain percentage of moisture (typically 3.7% for DOT 4). A higher wet boiling point indicates better resistance to performance degradation over time as the fluid ages and absorbs atmospheric moisture.

How should I dispose of old brake fluid?

Brake fluid is hazardous waste. Do not pour it down drains or into the environment. Contact your local waste disposal facility or auto parts store for information on proper disposal methods.

Troubleshooting

Brake pedal feels spongy or fades under heavy use

This often indicates the brake fluid has absorbed moisture or has reached its boiling point. Ensure the system was properly flushed and refilled with fresh EXP600 Plus, and consider a full fluid replacement if the issue persists or if the fluid is old.

Brake fluid appears contaminated or discolored

Contamination can lead to poor performance and component damage. Drain and flush the entire brake system thoroughly and refill with new Wilwood EXP600 Plus fluid. Identify and address the source of contamination.

Difficulty achieving a firm pedal after bleeding

Ensure all air is removed from the system using the correct bleeding procedure. Check all lines, calipers, and master cylinder for leaks. Over-tightening bleed screws can also cause issues.

Pros and Cons

Pros

  • Exceptional performance under extreme heat, preventing brake fade
  • Maintains a firm and responsive brake pedal during demanding use
  • Resistant to aeration and compressibility for consistent braking
  • Exceeds standard DOT 4 requirements for superior reliability
  • Suitable for both professional motorsport and high-performance street applications

Cons

  • Higher cost compared to standard DOT 4 brake fluids
  • May be overkill for typical daily driving conditions
  • Requires careful handling and storage due to its hygroscopic nature
  • Availability might be limited to specialized automotive parts retailers

Setup, Compatibility & Care Instructions

Setup: Always follow the vehicle manufacturer's specific brake bleeding procedures. Ensure the entire brake system is flushed thoroughly to remove old fluid before introducing EXP600 Plus. Use clean, dedicated brake fluid transfer equipment to avoid contamination.

Compatibility: This fluid is a DOT 4 type. It is compatible with most rubber brake components, seals, and hoses designed for DOT 3, DOT 4, and DOT 5.1 fluids. *Do not* mix with silicone-based DOT 5 fluids.

Care: Store the bottle in a cool, dry place, tightly sealed. Brake fluid is hygroscopic (absorbs moisture from the air), which degrades its performance. Once opened, use the fluid as soon as possible. Inspect brake fluid levels regularly and perform a full system flush and replacement according to your vehicle's service schedule or at least annually for high-performance applications.
