How Often Do I Need to Change My Brake Fluid – Like all fluids in a car, the level of brake fluid deserves regular attention. But for your safety, keep in mind that its replacement must be given to a professional.
Check the brake fluid level
A check every quarter is perfect. The level must be between the “mini” and “maxi” indicators engraved on the small jar generally placed above the brake master cylinder.
The Too generous filling does not cause any deterioration. But it is normal for the level to drop gradually over time: it corresponds to the lengthening of the brake calipers (this is what makes them catch up on the pads). For this reason, the level of the “maxi” Mark is never reset when the brakes are worn because when the platelets are changed, the overflow will overflow the tank.
Low level: Check Brake Pads
If the level is close to the Mini, check the status of your pads. If worn, replace them: the level will automatically rise by pushing the pistons out of the calipers. On the other hand, if they are new or poorly worn, this is likely to be a leak in the braking system. Especially when you notice by braking slowly that your pedal is sinking to the floor. Please consult with a specialist without delay.
Change the brake fluid
The brake fluid tends to lose its qualities over time. Think about changing it every two years or 50 000 kilometers. The quality of the brake fluid is also important. A dot index is used to identify the heating resistance of the liquid. ABS-equipped vehicles are systematically mounted with dot indices greater than 4.
The purge of the brake system is an operation that engages your safety. By caution, it is better to entrust it to a professional, especially if your car is equipped with an ABS: in fact, any presence of air bubbles in the hydraulic power plant of the ABS is irreparable! It is then the plant that needs to be changed.
