Brake fluid is a vital element for the proper functioning of the braking system. of your car This fluid is a hydraulic fluid that makes it possible to transmit the force exerted on the pedal to the brake cylinders in the wheels of cars, motorcycles, vans and some advanced bicycles.

Currently there are different types of brake fluid, of which DOT3, DOT4 and DOT5 have the same color. However, there is not one that can be used in all cars, as all car manufacturers specify which fluid your vehicle should use.

Regardless of what type of brake fluid your car uses, it is very important that you always have the right level and that you replace it at the recommended times. Don’t wait until it doesn’t work or the liquid is black.

Why is the brake fluid black?

We are sorry to say that when brake fluid turns black it is because its liquid is highly contaminated. When this happens, the pressurizing ability of the brake system is reduced and brake performance may be affected.

Also, black brake fluid means that the rubber gasket has deteriorated and the fluid in the tank is too old and needs to be replaced. In fact, it turns out that brake fluid contaminants attack rubber seals and washers. The black color in the liquid is the carbon particles from the rubber pads.

After a while, your brake fluid will collect enough contaminants and cause the color to begin to change. This change will change from clear/yellow to a darker yellow, and when the brake fluid is brown or black, this can seriously affect the brake system.

It’s important that you don’t let your car’s brake fluid reach that level of contamination. It is best to replace it at the times that the manufacturer recommends and check it constantly to prevent it from turning black.
