How to Bleed Air After Changing Brake Fluid?

[DeMaya]

Methods for bleeding air after changing brake fluid: 1. Connect a bottle filled with water to the bleeder valve using a hose. One person presses the brake pedal inside the car while another observes if the dirty fluid has been completely drained. Add new brake fluid and continue pressing the brake pedal until clear new fluid comes out of the bleeder valve and no bubbles are seen in the water bottle. 2. Use a vacuum fluid extractor to suck the old brake fluid out from the bleeder valve. After adding new brake fluid, continue extracting until the discharged fluid is clear and free of air. Situations requiring brake fluid replacement include: 1. When brake fluid absorbs moisture or contains impurities; 2. When the vehicle experiences inconsistent braking performance during normal driving, the brake fluid should be replaced promptly; 3. When the wheel cylinder rubber cup expands excessively; 4. Brake fluid should be replaced every two years.
