Our automatic brake fluid bleeder is engineered for single-person operation, combining efficiency, durability and portability. The brake fluid changer uses pulse pressurization technology   to avoid the generation of air bubbles and the water absorption of brake fluid during the filling process.  It changes the traditional way of exchanging the brake fluid by two people. One person can easily exchange the brake fluid in just 4-10 minutes, which will save you a lot of time and labor costs.
