One-way check valve allows air and brake fluid to escape, but will not allow air to re-enter the system. Works with most brake bleeder valves. Makes bleeding and servicing hydraulic brakes a one person job. Note: This tool requires priming and will not bleed air from a dry system. Saves time and frustration.
