Carlube Dot 4 ESP Brake Fluid is a synthetic brake and clutch fluid developed for use in vehicles with electronic stability program (ESP) systems, it has a much lower viscosity than traditional Dot 4 which will maximise the effectiveness of these more Advanced Braking Systems for improved braking and will help to reduce skidding in all driving conditions. Carlube Dot 4 ESP provides high performance and protection exceeding FMVSS116 Dot 3 and Dot 4 and SAE J 1703 specifications. It will mix safely with other Dot 3 or Dot 4 brake fluids which conform to the same specification and it is also ideal for all vehicles with ABS.
