Speed Bleeder Screws allow true one-person brake bleeding with no special equipment and without a compressed air source. When the Speed Bleeder screw is opened, a one-way ball check valve lets air and fluid out, but nothing back in.
Speed Bleeders are externally identical to our standard bleeder screws. Some other brands use the seat as the moving part, creating potential leak points. Our Speed Bleeders give you the convenience of a check valve without sacrificing the reliability of a standard bleeder screw. The 5/16-24 threads have pre-applied sealant to prevent air leaking in while bleeding.
Tech Tip: Use two of our Part No. 3139 Brake Bleeder Bottles (sold separately) to bleed the front and rear brakes simultaneously! This prevents the brake bias bar from binding and allows a full stroke on each master cylinder, making the job even more efficient.
