Brake Fluid Comparison Chart
Equilibrium Reflux Boiling Point (ERBP) dry is "when you get the material in a reflux state where the hot brake fluid hits the top of a cup, drips down back into the jar and you record the temperature when it is in “reflux” in a consistent fashion." Our Torque RT700® has been tested to meet and exceed this DOT4 and FMVSS116 standard.
Boiling point (Extreme) values on the other hand is if you were to hit it with heat for so long that it turns into another form (whether it is black goo, whether it evaporates, etc.) and you record “a temperature” to get there at one time. We use the extreme value as it keeps consumers better informed with a temperature limit where it can be reached but recommend not surpassing.
Boiling Point is NOT the same as ERBP / WERBP! ERBP will always be lower than the Boiling Point. ERBP is the minimum standard requirement for the brake fluid to be road legal.

Red indicates where the brake fluid did not meet the SAE J1704 and/or FMVSS 116 requirements.
Yellow indicates where brake fluid did not meet the manufacturer's performance claims.
*While we have only listed competitor M1 and M2 and a few others, the performance characteristics are applicable to a large number of other brands of fluids as they all come from mostly one manufacturer.
For mobile devices, best viewed in horizontal format.
