Once the Speed Bleeder check valves are installed, they become a permanent part of the brake system. When it is time to bleed your brakes, you loosen the Speed Bleeder check valve 1/4 turn and pump your brake pedal or clutch lever. When the pedal/lever is depressed the pressure generated, opens the check valve letting air and brake fluid out of the end of the Speed Bleeder check valve. When you release the pedal and it returns to the top position, the check valve closes and prevents air from reentering the system through the Speed Bleeder check valve. When bubble free fluid is evident you close the Speed Bleeder check valve. In the closed position it works just like your stock bleeder screw and prevents any brake fluid from leaking out. It generally takes about 5 pumps to purge each caliper or wheel cylinder. That is all there is to bleeding your brakes. If at a later date you need to bleed your brakes, the patented thread sealing system makes it easy to open the bleeder screw to perform the bleeding operation.

Purpose and function of utilizing Speed Bleeders: Perform brake bleeding when brakes become spongy or you suspect of having air in the brake / clutch system. Use to perform complete brake and clutch fluid change during scheduled maintenance. A "one" person operation.


Features of SPEED BLEEDER check valves.

Made in the USA

Stainless steel spring

Stainless steel ball

Brass retainer

The threads are roll formed. This process results in a stronger and smoother thread than cut threads.

The chamber for the ball and spring is precision reamed and the seat for the stainless steel ball is machined to exacting tolerances.

Zinc chromate plating withstands a 30 hour salt spray.

Patented thread sealing system seals the threads when the bleeding operation is performed, preventing air from being sucked back into the system.

The pre-applied thread sealant also displaces air and moisture during thread engagement preventing rust, which usually results in rounded off corners on the hex or busted off bleeder screws making it necessary to replace the caliper or brake cylinder. The application of thread sealant thus makes it easy to loosen or remove the bleeder screw at any time.
