DIY: How to Bleed Brakes Using a Vacuum Pump

Video tutorial on how to bleed your brakes with a vacuum pump. If you’ve replaced a wheel cylinder, caliper, flex lines, brake lines, master cylinder, or any other brake components associated with brake fluid, you will need to bleed the air from the brake system. Other times if your brake pedal feels spongy, air could possibly be present in the lines and will need to be bleed. This applies to both disk and drum brakes. For this example I will be using disk brakes. When working with brake fluid, DO NOT allow it to come in contact with the paint. Either by dripping or even just the residue on your hands. Brake fluid can damage your vehicle’s paint.
