DOT 3 and DOT 4 Synthetic Brake Fluid

Product code : BFLVCN-EA

Maximum ABS and traction-control performance

AMSOIL DOT 3 & 4 Synthetic Brake Fluid maintains maximum ABS and traction-control performance. Brake fluid acts as a hydraulic fluid, transferring power and lubricating brake system components while also preventing corrosion. It must contend with extreme heat and the inevitable moisture contamination that can lead to a brake system failure.

Fights Water Contamination
Water contaminates the brake system by seeping through microscopic pores in flexible brake lines and seals and through the reservoir fill cap. Brake fluid itself is hygroscopic (attracts moisture). Once introduced to the system, water reduces boiling points and compromises performance. It corrodes brake parts, lines and seals, leading to eventual failure. AMSOIL DOT 3 & 4 Synthetic Brake Fluid's superior wet boiling points counteract these problems. It lubricates and protects intricate brake components despite the inevitable water contamination. A nitrogen blanket is added to each bottle during manufacturing to purge moisture and ensure the maximum level of performance.

Firm Pedal Feel
The extreme pressure and high heat common to brake systems can push brake fluid beyond its boiling point, causing it to vaporize or "boil-off." Water contamination can accelerate the process. This leads to a spongy or unresponsive feeling in the brake pedal (vapor lock). In contrast, the unique chemistry behind AMSOIL synthetic brake fluids increases boiling points well beyond DOT standards, even when contaminated with 3.7 percent water. AMSOIL Brake Fluids maintain a stable viscosity over a wide temperature range and flow easily at the high pressures generated in today's automotive brake systems to deliver solid, reliable braking. Maximum ABS and Traction-Control Performance AMSOIL DOT 3 & 4 Synthetic Brake Fluid's low-viscosity (817 cSt) provides superior cold-weather performance and excellent ABS and traction-control responsiveness. It covers a broad range of applications and exceeds DOT 3, 4 and 5.1 specifications.

APPLICATIONS
Use AMSOIL DOT 3 & 4 Synthetic Brake Fluid in passenger car, light truck and powersports applications that require a DOT 3, 4 or 5.1 product. Do not mix with DOT 5 fluid. Refer to your owner's manual regarding the proper change interval for your brake fluid and to determine the correct DOT classification. Change fluid every two years for maximum performance.

    Amsoil always outperforms
    By  ERIK,  a  Verified Buyer  from  Florida   on  April 15, 2023
    We had to do an engine swap and bought generic oil after install to test it out. Once it was driven a while we put in amsoil and the oil pressure increased significantly. That's why all of our equipment from compressors to trucks only gets amsoil. They are unmatched in every field.
    Bottom Line
    Yes, I would recommend this to a friend.

    Purchased this to replace the brake fluid in my 2020 GMC Sierra, which had become contaminated with moisture. Product was shipped quickly and carefully. Has been in my truck over 600 miles so far, and seems to be working very well. I’ll be ordering more, to flush the hydraulic fluid system in my Harley.
