Brake fluid is a key element of the braking system. It transmits the force from the pedal to the wheels to slow down or stop your vehicle safely. However, over time, this liquid loses its properties, compromising braking performance and your safety on the road.
Signs of brake fluid to be replaced
Spongy or soft brake pedal
A less reactive brake pedal may indicate degradation of the liquid or the presence of moisture in the circuit.
Braking distance elongation
A used liquid reduces the efficiency of the system, thereby increasing the distance needed to stop.
Change of colour of the liquid
A healthy brake fluid is clear or slightly amber. When it becomes dark or opaque, it is a sign that it has lost its properties.
Lighted informants on the dashboard
Some modern vehicles have sensors that detect braking anomalies. If an indicator lights up, check the system quickly.
Why regularly replace the brake fluid?
The brake fluid is hydrophilic, which means that it absorbs moisture from the air. Over time, this humidity can:
Reduce braking efficiency: The formation of steam bubbles during heavy braking reduces hydraulic pressure.
Accelerating internal corrosion: Humidity can damage the metal components of the braking system.
How often to change the brake fluid?
The frequency of replacement varies according to several criteria:
