For the most demanding motorcyclists, Brembo has two different types of brake fluid: Brembo DOT 4 Sport.EVO 500++, formulated for enthusiasts, and Brembo Racing LCF 600 PLUS, offering the best possible characteristics under stress for those who race on the track.

The main characteristic of a brake fluid is its extremely low compressibility coefficient and notable resistance to high temperatures (boiling point), preventing any great variation in its volume given the high working temperatures that it can reach during the braking phases.

These temperatures depend on the continuity and intensity of the braking action; in fact the liquid has a working temperature range from about -40C° to well over 200°C so the higher the boiling point, the better the characteristic of the liquid.

As a result of its characteristics, brake fluid easily absorbs moisture. This leads immediately to a reduction in its performance to the point where it becomes completely inefficient. Owing precisely to its hygroscopicity (i.e. the tendency to absorb moisture from the air), the brake fluid deteriorates over time and loses the above-mentioned characteristics, developing a tendency to produce water vapour bubbles as the temperature increases (the “Vapour Lock” effect, whereby vapour bubbles develop). This gradually lengthens the action of the brake lever once it has warmed up.

The chart shows the deterioration of the various brake fluids on the basis of the moisture absorbed. You can see that the deterioration of the brake fluid characteristics is immediate, even in the case of just a small percentage of water. It’s therefore a good idea to keep it under control, replacing it when necessary.
For this reason, the brake fluid must have certain specific characteristics:

° be as incompressible as possible
° have a high boiling point
° have low viscosity
° be chemically stable
° be chemically inert in relation to gaskets

Brembo Racing LCF 600 PLUS

Brembo Racing LCF 600 PLUS brake fluid is specifically formulated to ensure the best possible performance: it’s used by the Top Teams of MotoGP and SBK. Without any type of exception, this is the best brake fluid available on the market. It has a low compressibility factor at high temperatures, and a high boiling point.

Given its notable hygroscopicity though, its lifespan is limited (it depends on many factors, but is generally between 2000 and 4000km). Brembo Racing LCF 600 PLUS goes beyond the requisites of U.S. specification FMVSS 116 DOT4.

It’s compatible with all the Brembo braking systems and can be mixed with other DOT3 and DOT4 racing fluids (you are advised to fully drain all the old fluid from the system however).

Brembo LCF 600 Plus must not be used in braking systems containing parts in magnesium.
