Castrol React SRF Racing Brake Fluid - 1ltr. ❭ REACTSRF
React SRF Racing Brake Fluid – High Performance Motorsport Fluid 1ltr
React SRF Racing is an ultra high-performance brake fluid engineered for the most demanding driving conditions, including motorsport and high-performance track use. This is Not your standard DOT 4 – much higher spec
With a dry boiling point exceeding 300°C, this advanced brake fluid delivers exceptional resistance to vapour lock, maintaining consistent braking performance even under extreme heat and sustained heavy braking.
Unlike standard brake fluids, React SRF Racing is formulated to retain its high vapour lock resistance throughout its service life, ensuring dependable performance over extended use.
Supplied in a convenient 1 litre bottle, it is the ideal choice for performance enthusiasts, track day drivers, and professional motorsport applications.
Key Features
• Extremely high dry boiling point (over 300°C)
• Outstanding resistance to vapour lock
• Maintains performance throughout service life
• Designed for motorsport and high-performance use
• Suitable for extreme braking conditions
• Supplied in 1 litre bottle
Performance Benefits
Consistent Braking Under Extreme Heat
Maintains braking efficiency even during prolonged track use.
Superior Vapour Lock Resistance
Prevents brake fade in high-temperature conditions.
Long-Lasting Performance
Retains key properties throughout its service life.
Applications
Ideal for:
• Motorsport and racing applications
• Track day vehicles
• High-performance road cars
• Upgraded braking systems
The OE Match Brake Fluid Bleeding Kit is a high-quality service tool designed to simplify the bleeding of hydraulic brake and clutch systems on Porsche vehicles. Manufactured to OE standards for fit, durability and ease of use, this kit enables efficient removal of trapped air from the hydraulic system, ensuring a firm brake pedal, consistent braking performance and reliable clutch operation where applicable.
Illustrated booklet makes your troubleshooting easy.
Designed for both professional workshops and experienced home mechanics, the kit provides a secure connection to the brake fluid reservoir, allowing controlled bleeding during brake fluid replacement or hydraulic system repairs. Manufactured from durable, brake-fluid-resistant materials, it is engineered to provide reliable performance during repeated servicing.
What This Product Does:
- Enables efficient bleeding of the hydraulic brake system.
- Removes trapped air from brake and clutch hydraulic circuits.
- Helps restore a firm and responsive brake pedal.
- Supports complete brake fluid replacement during servicing.
- Reduces the risk of air remaining in the hydraulic system.
- Assists in maintaining consistent braking performance.
- Can be used during brake caliper, master cylinder or hose replacement.
- Helps ensure safe and reliable hydraulic system maintenance.
Symptoms Of Wear Or Failure:
- Damaged or cracked reservoir adapter.
- Leaking hose connections.
- Worn or perished seals.
- Blocked or restricted fluid passages.
- Damaged pressure fittings.
- Poor sealing to the brake fluid reservoir.
- Cracked or kinked hoses.
- Corrosion or damage to connectors.
- Difficulty maintaining consistent bleeding pressure.
- Fluid leakage during operation.
Why Replacement Matters:
- Effective brake bleeding is essential whenever brake fluid is replaced or hydraulic components such as calipers, hoses, master cylinders or slave cylinders are serviced. Even small amounts of trapped air can reduce hydraulic pressure, resulting in a soft brake pedal, inconsistent braking performance and reduced driver confidence.
- A worn or damaged bleeding kit may leak, fail to maintain pressure or introduce air into the system, making brake servicing more difficult and less effective. Reliable equipment helps ensure the hydraulic system is fully bled, allowing the brakes and clutch to perform as intended.
- Replacing a damaged or ageing brake fluid bleeding kit ensures safe, efficient and reliable hydraulic servicing. An OE Match kit offers durable construction, dependable sealing and workshop-quality performance, making it an essential tool for maintaining the braking and clutch systems of your Porsche.
