The other end of this tubing connects to the MityVac pump. You must first open the bleeder screw on the caliper being serviced.
Vacuum Bleed Brakes with MityVac: Step-by-Step Guide
This method leverages vacuum technology to pull fresh brake fluid through the system, effectively removing air bubbles and old fluid without the risk of introducing new air into the master cylinder. Unlike the traditional "gravity bleed" method, which relies on opening the bleeder valve and hoping fluid and air flow out, the MityVac actively pulls fluid and air through the system from the master cylinder to the farthest caliper.
Furthermore, it is essential to monitor the brake fluid level in the master cylinder reservoir throughout the process. This active pulling action is far more effective at eliminating trapped air, and it prevents the common mistake of introducing air back into the system when the bleeder screw is closed.
Vacuum Bleed Brakes with Mityvac: Step-by-Step Guide
Performing a brake bleed with a MityVac tool transforms a traditionally messy, two-person chore into a clean, efficient, and precise one-person operation. Maintaining System Integrity One of the most critical aspects of using a MityVac is the maintenance of a closed system to prevent air contamination.
