Our High-Performance Brake Fluid has been specially formulated to provide the highest performance under the worlds toughest racing conditions, where braking systems must operate at very high temperatures.

  • Compatible with Dot 5.1 systems
  • Reduces lever fade and brake pump
  • For unrivalled braking performance

Use in a well-ventilated area. Follow brake manufactures instructions for bleeding/fluid replacement. For best results bleed the system with fresh fluid before each race, especially if the brakes are excessively hot and /or the conditions are humid. Do not mix with other brake fluids.

NB: Brake fluid damages paintwork - if spilt, wash off immediately with plenty of water. Not suitable for brake systems requiring a mineral based fluid. Not recommended for use with components made from magnesium or alloys with high magnesium content.

Contamination with dirt, water, petroleum products or other materials may result in brake failure or costly repairs. Store brake fluid only in its original container. Keep container clean and tightly sealed to prevent absorption of water. Caution: Do not re-fill container and do not use for other liquids.
