Amsoil DOT 3/4 DOT 3/4 Brake Fluid 355mL Bottle BFLVCN

Description

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. AMSOIL synthetic brake fluids surpass Department of Transportation (DOT) requirements and provide auto enthusiasts and racers with a brake fluid that delivers superior high-temperature performance.

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 synthetic brake fluids’ superior wet boiling points counteract these problems. They lubricate and protect intricate brake components despite the inevitable water contamination. Nitrogen 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 todays automotive brake systems to deliver solid, reliable braking.

Maximum ABS and Traction-Control Performance

AMSOIL DOT 3 & 4 Synthetic Brake Fluid’s low-viscosity 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.
