Wilwood Hi-Temp 570 Racing Brake Fluid - High Boiling DOT 3

In this review the Wilwood Hi-Temp 570 Racing Brake Fluid is evaluated from the perspective of performance-minded drivers and racers who need a DOT 3 fluid that resists vapor lock under extreme heat. The bottom line: this fluid is for anyone needing a high dry-boiling point in a ready-to-use 12 ounce sealed bottle, and its chief selling point is a guaranteed minimum 570 F dry boiling temperature that helps preserve braking performance in severe conditions. The sealed containers also reduce moisture absorption, which is critical for maintaining boiling characteristics over time.

Key Features

• Minimum 570 F dry boiling point: Provides a high heat threshold to reduce the risk of vapor lock during heavy use or racing conditions.
• Low viscosity: Makes bleeding the brake system easier and helps avoid aeration from excessive pedal pumping.
• Hermetically sealed 12 oz bottle: Keeps moisture out so the fluid retains its boiling performance until opened and used.
• Available in single bottles or multipacks: Lets buyers choose a single replacement bottle or stock up with six-packs or case quantities for frequent maintenance.
• Formulated for racing: Specifically designed to meet the severe heat requirements encountered in automotive racing applications.

Who It's For

The Wilwood Hi-Temp 570 is aimed at racers, track-day drivers, and anyone who pushes braking systems hard enough that a standard DOT 3 fluid might boil. It suits owners of performance cars and vintage race cars where DOT 3 compatibility is required and a high dry boiling point is essential.

Those who should look elsewhere include drivers who need DOT 4 or DOT 5.1 performance characteristics, or users who prefer larger refill containers for frequent shop use; the 12 oz sealed format is best for preserving fluid until use rather than bulk dispensing.

Pros & Cons

Pros

• High minimum dry boiling point reduces brake fade risk in demanding conditions.
• Low viscosity eases bleeding and reduces the chance of aeration during maintenance.
• Sealed 12 oz bottles prevent moisture contamination prior to use, preserving performance.

Cons

• Only supplied in 12 oz sealed bottles, which may not be ideal for shops that prefer bulk containers.

Frequently Asked Questions

Is this fluid suitable for racing?
Yes. It is formulated with a minimum 570 F dry boiling point specifically to withstand racing heat conditions.

Can this replace standard DOT 3 in a street car?
Yes, it is DOT 3 compatible and can be used in street cars, though it is designed for higher-heat applications.

Why are the bottles sealed?
The hermetic seal prevents moisture absorption that would lower the boiling point, preserving performance until the bottle is opened.
