Product Code: BFR |
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 fl exible brake lines and seals and
through the reservoir fi ll 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
fluid's superior wet boiling points counteract these problems. They
lubricate and protect 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. |

Ultra-High Boiling Points
AMSOIL DOMINATOR® DOT 4 Synthetic Racing Brake Fluid features
ultra-high boiling-points of 410ºF (wet) and 580ºF (dry). It
maintains a low compressibility during the most extreme racing
conditions.
*Dry equilibrium reflux boiling point (ERBP)–the
boiling point of new, freshly opened brake fluid.
**Wet
ERBP–the boiling point of brake fluid having absorbed 3.7 percent
water. Only 3.7 percent water contamination is often sufficient to
reduce a DOT 3 fluid’s boiling point below the DOT minimum.

Applications
Use AMSOIL DOMINATOR® DOT 4 Synthetic Racing Brake Fluid in racing
applications that require a DOT 4 product. Change fluid once a year
for maximum performance.
