For those of you that demand optimum performance from your vehicle's braking system, there is a new Brake Fluid type that should interest you.
Made by Bosch, the new fluid designation is ESI6-32N -- replaces and is compatible with: DOT 3; DOT 4; and DOT 5.1.
The new fluid has a lower viscosity, which allows for better functioning of anti-lock brake systems, plus the added bonus of longer service life. Fluid life is double that of the standard DOT 3 fluid.
Dry Boiling Point = 270 C. - 518 F.
Wet Boiling Point = 185 C. - 365 F.
Comes in a 32-OZ metal CAN -- available at O'Reilly's and Amazon.com.
