$23.78
Type: ISO Class 6 Dot 4 Brake Fluid Specifications: Meets FMVSS 571.116, DOT 4/DOT 3, SAE J1703 as well as ISO 4925, Class 6 specifications. Volume: 1 Liter The optimal brake fluid for electronic brake systems Since the introduction of ESP, brake fluid must decelerate individual wheels in fractions of a second in order to stabilize the vehicle in critical situations (e. g. a skid). The development of particularly thin bodied brake fluids such as Original ATE SL.6 have been essential in ensuring the rapid response times required for ESP can be attained. The requirement for such fluids has already been incorporated into the design of the ESP system. With conventional brake fluids the system’s reaction times (in critical situations) may be several times longer than with Original ATE SL.6. In practice this may mean that the system cannot stabilize the vehicle. Advantages of Original ATE SL.6

Product Features:
  • Low viscosity (thin-bodied)
  • Permits fastest response by ESP
  • Optimum brake fluid for electronic brake systems like ESP, ABS, TCS, etc.
  • Improved handling safety owing to speedy response of ESP
