Understanding Brake Fluid
Brake fluid is a critical component in any vehicle’s braking system. It operates under high-pressure conditions, transmitting force from the brake pedal to the brake components. Brake fluids are categorized based on their boiling points, chemical composition, and intended applications.
There are three main types of brake fluids: DOT3, DOT4, and DOT5, with R2 fluid conforming to and exceeding DOT4 specifications. Understanding these categories is essential for selecting the right fluid for your vehicle.
Why Choose AP Racing Radi-CAL™ R2?
Exceptional Performance
Radi-CAL™ R2 is specially formulated to handle extreme conditions encountered in racing. Its dry boiling point of 312°C ensures that it won’t vaporize under intense heat, providing consistent braking performance. This is particularly crucial during endurance races where brake temperatures can soar rapidly.
Designed for Racing Applications
Unlike standard brake fluids, R2 is designed specifically for competition use. The fluid’s unique properties allow it to maintain its efficacy even in the face of the extreme stresses that racing environments impose. Brands like www.essexparts.com and competitionmotorsport.com recognize R2 as a top-tier option for both amateur and professional racing teams.
Compatibility
While R2 fluid meets DOT4 specifications, it is essential to note that it should not be used with components made from magnesium. This compatibility factor is crucial for ensuring the longevity and reliability of your braking system. Always consult your vehicle’s specifications to ensure proper use.
How to Use R2 Racing Brake Fluid
Installation Process
-
Drain Existing Fluid: Before introducing R2 fluid, ensure that the brake system is completely drained of the previous fluid. This prevents contamination and ensures optimal performance.
-
Flush the System: Thoroughly purge the brake system with fresh R2 fluid to remove any residual moisture or contaminants.
-
Fill with R2 Fluid: Once the system is clean, fill it completely with Radi-CAL™ R2 fluid. Make sure to follow the manufacturer’s recommendations for your specific vehicle.
Maintenance Tips
- Regularly check the brake fluid level and top up if necessary.
- Monitor the fluid’s condition for any signs of contamination or degradation.
- Consider changing the fluid periodically, especially after intense racing sessions.
