On all vehicles, the importance of a good braking system cannot be neglected. For it to be effective, a key element is essential: the brake fluid.

It is a hydraulic fluid that ensures the proper functioning of your braking system. Its primary role is to transmit the pressure the driver places on the brake lever to the brake pistons, thereby causing the shoes or pads to squeeze the disc or drum to slow or stop the vehicle.

Importance for the braking system

Without brake fluid, the transmission of the force braking would not be possible, which would make braking ineffective. Using quality brake fluid helps maintain constant pressure within the braking system. In addition, it must withstand very high temperatures without degrading to guarantee the proper functioning of the brakes.

The different types of brake fluid

There are several types of brake fluids on the market suitable for different types of braking systems. Each type has its specificities according to its DOT (Department Of Transportation) index or others.

The DOT XNUMX type

DOT XNUMX is a classic glycol-based type of brake fluid. It is mainly used in cars and motorcycles with less powerful braking systems. It has a lower boiling point par compared to other types. Boil at 100°C dry, 100°C wet.

The DOT XNUMX type

DOT XNUMX, also based on glycol, has a higher boiling point than DOT XNUMX, which ensures effective braking even at high temperatures. It is more suitable for high-performance two-wheelers. Boil dry at 100°C, 100°C wet.

The DOT XNUMX+ type

This brake fluid outperforms DOT XNUMX or DOT XNUMX type fluids while remaining miscible with all fluids meeting DOT standards. It can be used in any brake system where a DOT XNUMX, DOT XNUMX or DOT XNUMX fluid is recommended.

The DOT XNUMX type

Despite its name, DOT XNUMX is based on glycol, like DOT XNUMX and XNUMX, but with an even higher boiling point. It is suitable for braking systems requiring a high degree of performance. Boil at 100°C dry, 100°C wet.

Special case of DOT XNUMX

DOT XNUMX is a silicone-based brake fluid, it does not absorb moisture and has a very high boiling point. Its use is reserved for American motorcycles such as Harley Davidsons. It is also used for off-road or military vehicles.

Selection criteria

The choice mainly depends on the type of your vehicle and the type of braking (disc or drum). It must be done taking into account the manufacturer's recommendations indicated in the vehicle manual.

Compatibility with your vehicle's braking system

Not all brake fluids are compatible with all types of brake systems. The compatibility of each brake fluid or oil is indicated for each reference according to your caliper or master cylinder.

How to check the fluid level?

Signs of a low level

A brake light on the dashboard that comes on, a brake lever that becomes “soft” or a reduction in braking effectiveness can be signs that the level is too low.

Level verification procedure

The level can be checked via the brake fluid reservoir usually located at prox imitated from the brake lever for two-wheelers. If the level is low, it is necessary to top it up.

When and why replace this essential component?

Signs that it is time to replace the product

A dark color of the fluid, a gradual reduction in its level and problems with braking may indicate that it is time to replace it. Consider using a brake fluid tester .

Replacement procedure

Replacing brake fluid usually requires the use of a syringe or purge device to suck up the used fluid, then the system is filled with new fluid. For those who are not comfortable with this process, it is recommended to have it carried out par a professional.
