from

$15.49
Prestone® MAX DOT 4 Motor Vehicle Brake Fluid is our highest grade formula, maximizing performance vs. DOT standard. Prestone MAX is our best brake fluid at protecting against overheating and brake fade. With 75,000 mile fluid life, our longest life fluid has 1.5X more miles between replacement than regular Prestone DOT 3. Prestone MAX has superior performance in severe braking conditions when compared to regular Prestone DOT 4, which means even more piece of mind about the braking system. This synthetic fluid starts with our highest dry boiling point giving our best protection against performance decline due to water absorption. Prestone MAX DOT 4 is safe to use in all DOT 4 braking systems, ABS, disc or drum, and can mix with any DOT 4 fluid. Mixing Prestone MAX with other fluids will lower the performance rating for miles and boil points, for best results replace completely with Prestone MAX DOT 4. It is recommended to only use the DOT fluid specified for your car. Using a different DOT product can affect the boiling point or replacement interval if the wrong fluid is used.

Product Features:
  • 75,000 Mile Fluid Life
  • Prevent Overheating & Brake Fade with Our Highest Grade Formula. Prevents corrosion of all metals within the braking system.

ATE – SL.6 DOT4 Low Viscosity Brake Fluid – 1 Liter (Part No.3C100237682ATE)

$21.87
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
