Stahlbus Oil Drain Valves With Racing Caps - Steel (M14x1.25x12mm)

Q: What is a brake bleeder valve? Why buy one?
A: Brake bleeder valves are small threaded valves that attach to your brake calipers and slave cylinders and allow you to bleed air and bubbles out of the hydraulic fluid in your brake system. In order to bleed the system you loosen these valves slightly allowing air and fluid to exit and then close the valve before any air can return to the system. These valves are extremely vulnerable to becoming stripped and frequently require replacement, especially on older vehicles. When it comes time to change your brake bleeder valves there are upgrade options available. New bleeder valves have been designed with internal spring loaded ball bearings that act as one-way valves. When you open one of these upgrade valves and push the pedal to the floor, fluid and air are allowed to exit like normal but the spring loaded ball bearing prevents any air from being sucked back in. This makes brake bleeding a one man job so you no longer have to trade favors with a friend to get your brakes finished.
