Red Line RL-700 Racing Brake Fluid DOT 4 - Typical Dry Boiling Point: 635°F (335°C) Typical Wet Boiling Point: 401°F (205°C) Specially formulated to provide the highest performance under racing conditions where braking systems operate at very high temperatures For best results ...Red Line RL-700 Racing Brake Fluid DOT 4 - Typical Dry Boiling Point: 635°F (335°C) Typical Wet Boiling Point: 401°F (205°C) Specially formulated to provide the highest performance under racing conditions where braking systems operate at very high temperatures For best results, bleed the braking system with fresh fluid before each race, specifically if the brakes are excessively hot and/ or the conditions are humid Do not mix with other brake fluids, otherwise outstanding performance may be compromised RL-700 conforms to and exceeds U.S FMVSS No.116 DOT 4 Exceptionally low compressibility RL-700 has the highest boiling point of all road legal brake fluids ever produced Red Line now offers its own high-performance brake fluid perfect for street or track use. RL-600 is engineered to maintain viscosity, lubricity and low compressibility at extreme temperatures to help safeguard against brake fade and vapor lock in racing, performance and street applications. Two options for high performance and racing brake fluids that have been engineered to help safeguard against brake fade and vapor lock in racing, performance, and street applications.
