Project Mu PSF306 G-Four 335 High-Performance Racing Brake Fluid 1L

The Project Mu PSF306 G-Four 335 is a premium, 100% synthetic glycol-based racing brake fluid engineered for drivers who demand maximum braking performance under extreme heat conditions. Developed in Japan by one of motorsport's most respected brake system manufacturers, this fluid is trusted on the track and on the street.

Key Features:

• Extreme Dry Boiling Point: 335°C (635°F) — resists brake fade even under repeated hard braking
• Wet Boiling Point: 221°C (430°F) — maintains performance even after moisture absorption
• 100% Synthetic Formula: Provides superior thermal stability and durability compared to conventional brake fluids
• Color-Indicator Technology: Fluid starts green and transitions to clear when it has lost its effectiveness — taking the guesswork out of maintenance intervals
• DOT 4 / DOT 5.1 Compatible Rating: Meets and exceeds DOT performance standards
• Sold in a 1-liter bottle — ideal for a full system flush

Important Usage Notes:

• This fluid is not compatible with other DOT brake fluids — a complete system flush is required before use
• Recommended change interval: every two years for aggressive or track-driven vehicles
• Monitor fluid color as an indicator of fluid health — bleed until green fluid is visible to confirm fresh fluid is in the system

The Project Mu G-Four 335 is the go-to choice for track day enthusiasts, time attack competitors, and performance street drivers who want a reliable, high-boiling-point fluid with a built-in maintenance indicator.
