| Features |
“Brake fluid focusing on stable pedal-feel under high
temperature for driving on the circuit” |
When people talk about
high performance brake fluid, they tend to focus on the smoke point. However,
we are more concerned with another important factor that the driver expects
during circuit driving which is how stable the pedal-feel remains after many laps.
To achieve a high level
of braking control, it is essential that change in every characteristic other
than brake pads be minimized. Therefore, “BF338” brake fluid - that prioritizes
high temperature performance - deliberately sacrifices low temperature (below -10℃)performance and focuses on circuit driving
conditions, without adhering to the DOT standard.
We have formulated it to
minimized metal corrosion and the swelling of rubber seals and gaskets to
support race car users and to balance high performance and endurance for a wide
range of users from street to competition.
When used in conjunction with
our brake pads this brake fluid will
contribute to a total braking system for users driving in harsh braking
conditions, such as circuit driving and with limited brake capacity. |

fluid in a passenger vehicle in a 6-12 month period. |
※2:As shown on the chart above, the kinetic viscosity for JIS standard of
-40℃ is outside the specification range for “BF338”.
Please avoid using if the outside temperature is
below -10℃. (It may be liable to impaired fluid response.)
Meets all criteria for metal corrosion, swelling of
the rubber and water-resistance, as set out in the JIS BF-4 (DOT4 equivalent)
specification. |
| Caution: Please do not mix
with other brake fluids. (Depending on the component, it may cause
deterioration.) |
