Make bleeding the brakes a "One-Man" job! Patented Speed Bleeders have a spring loaded, one way ball and check valve which replaces original bleeder valves in calipers and wheel cylinders. The check ball opens to allow old fluid and air out then closes automatically between pumps, preventing air from re-entering the system. Sold 2 per package.
