Upgrading your brake system is a crucial step in enhancing your vehicle’s performance, especially for those who push their cars to the limit. One of the most important components that often gets overlooked during this upgrade is brake fluid. Choosing the right brake fluid can significantly impact your braking performance, pedal feel, and overall safety. This guide will explore the best brake fluid choices available for upgraded brake systems.
Understanding Brake Fluid Types
Brake fluids are categorized mainly into two types: DOT (Department of Transportation) fluids and mineral oils. Each type has its properties, advantages, and disadvantages.
- DOT Fluids: These are glycol-based fluids that absorb moisture over time. They are rated by their boiling points, with higher ratings indicating better performance under heat.
- Mineral Oils: These are non-hygroscopic and do not absorb moisture. They are often used in classic cars and some motorcycle systems.
Key Factors to Consider When Choosing Brake Fluid
When selecting brake fluid for an upgraded brake system, consider the following factors:
- Boiling Point: Look for fluids with high dry and wet boiling points to ensure optimal performance under high-stress conditions.
- Compatibility: Ensure that the brake fluid is compatible with your brake system materials to prevent damage.
- Moisture Absorption: Consider how quickly the fluid absorbs moisture and its impact on braking performance over time.
- Temperature Range: Choose a fluid that can withstand the temperature range of your driving conditions.
Top Brake Fluid Choices for Upgraded Brake Systems
Here are some of the best brake fluid options for upgraded brake systems:
- Motul RBF 600: This racing brake fluid offers a dry boiling point of 312°C and is ideal for high-performance applications. It is known for its excellent resistance to moisture.
- Castrol SRF: With a dry boiling point of 590°F (316°C), Castrol SRF is designed for extreme conditions and is favored by professional racers.
- AP Racing 600: This fluid provides a high dry boiling point of 312°C and excellent performance in both racing and street applications.
- Wilwood EXP 600 Plus: Known for its superior performance, this fluid has a dry boiling point of 600°F (316°C) and is designed for racing environments.
- Valvoline SynPower Brake Fluid: A more accessible option, this fluid offers good performance with a boiling point of 265°C, suitable for street and occasional track use.
How to Change Brake Fluid
Changing your brake fluid is essential for maintaining optimal braking performance. Here’s a step-by-step guide:
- Gather Supplies: You will need the new brake fluid, a brake bleeder kit, a wrench, and a container for old fluid.
- Locate the Brake Fluid Reservoir: Open the hood and find the brake fluid reservoir, usually located near the back of the engine bay.
- Remove Old Fluid: Use a turkey baster or siphon to remove old brake fluid from the reservoir.
- Refill with New Fluid: Pour the new brake fluid into the reservoir, ensuring it is the correct type for your system.
- Bleed the Brakes: Start with the wheel farthest from the master cylinder. Use the brake bleeder kit to remove air from the lines until clear fluid flows.
- Check Fluid Levels: After bleeding all brakes, check the fluid level in the reservoir and top off if necessary.
Maintaining Your Brake Fluid
Proper maintenance of your brake fluid is crucial for safety and performance. Here are some tips:
- Regular Checks: Inspect the brake fluid level and condition regularly, especially before long trips.
- Change Intervals: Change your brake fluid every 1-2 years, or as recommended by your vehicle manufacturer.
- Storage: Store brake fluid in a cool, dry place and ensure the cap is tightly sealed to prevent moisture absorption.
- Watch for Contamination: Be cautious of any debris or discoloration in the fluid, as this can indicate contamination.
Conclusion
Choosing the right brake fluid for your upgraded brake system is vital for achieving optimal performance and safety. By understanding the different types of brake fluids, their properties, and how to maintain them, you can ensure your braking system operates at its best. Always prioritize high-quality fluids and regular maintenance to keep your vehicle performing safely on the road.
