The Millers Oils Racing Brake Fluid 320 Plus is designed for drivers of high-performance vehicles, including those participating in track days and competitions. Its primary benefit is the exceptionally high boiling point, ensuring consistent braking performance under extreme conditions and offering superior pedal feel. A key caveat is that it is not suitable for systems requiring mineral oil-based brake fluid. This fluid offers advanced protection and confidence for demanding braking systems.

DOT 3 and DOT 4 fluids have lower dry and wet boiling points than the Millers Oils Racing Brake Fluid 320 Plus. The 320 Plus has a significantly higher dry boiling point (over 320° C) designed for the extreme heat generated in motorsport, while standard DOT 4 fluids typically have dry boiling points around 230° C.
For general fast road use, changing the fluid every 1-2 years is recommended. For track day or competition use, more frequent changes, possibly after every few events, are advisable to maintain peak performance.
It is not recommended to mix this fluid with other brake fluids, as it can dilute its high boiling point and potentially affect performance. If changing fluid type, it is best to completely flush the system.
The Dry Boiling Point is the temperature at which the fluid will boil when it is fresh and contains no moisture. The Wet Boiling Point is the temperature at which it will boil after absorbing a small percentage of moisture (typically 3.7% for DOT 4 standards), indicating how performance degrades over time.
While it meets DOT 4 specifications, its primary design is for high-performance applications. For a standard road car without performance modifications or track use, a good quality standard DOT 4 fluid may be sufficient and more cost-effective. However, if you frequently drive spiritedly or want enhanced braking performance, it can be an upgrade.
The Technical Data Sheet (TDS) is usually available from the retailer or the manufacturer's website. It contains detailed specifications and properties of the brake fluid.
This typically indicates air in the system or that the fluid has absorbed too much moisture and its boiling point has been compromised. Bleed the brake system thoroughly to remove air and consider replacing the brake fluid if it is old or has been exposed to high temperatures.
This suggests a leak in the brake system. Inspect brake lines, calipers, wheel cylinders, and the master cylinder for any signs of fluid leakage. Do not drive the vehicle if a leak is suspected.
This is often due to the brake fluid boiling. Ensure you are using a high-boiling point fluid like the 320 Plus and that it has not been contaminated with water. Regular fluid changes are essential for preventing fade.
Compatibility: This brake fluid is compatible with most modern high-performance brake and clutch systems that specify DOT 4 fluid. Crucially, it is NOT suitable for vehicles that use mineral oil-based brake fluids (e.g., some older Jaguars or Citroens). Always consult your vehicle's service manual to confirm the correct brake fluid type before use.
Setup: When bleeding or flushing your brake system, ensure all old fluid is completely removed. Use clean tools and containers to avoid contamination. Fill the master cylinder reservoir to the indicated level.
Care: Brake fluid is hygroscopic, meaning it absorbs moisture from the atmosphere over time. This lowers its boiling point and can lead to corrosion. For optimal performance, it is recommended to flush and replace the brake fluid every 1-2 years, or more frequently for dedicated competition vehicles.
