Brake Caliper auto bleed nipple M7 7mm x 1mm x 1+ Nipple Cover
Auto bleeders with the built-in check valve have been around the motorbike scene for quite sometime. Fitting Auto bleeders to your brake calipers makes brake bleeding truly a one-person operation. Once installed it becomes a permanent part of the brake system.
When it is time to bleed your brakes you loosen the Auto Bleeder 1/4 turn and pump your brake lever. On depressing the lever the pressure generated opens the check valve letting air and old brake fluid escape the Auto Bleed nipple. Releasing the lever closes the check valve preventing any air from entering the system. When bubble free fluid is evident you close the Auto Bleeder.
In the closed position it works just like your OEM bleeder screw and prevents any brake fluid from leaking out. It usually takes about 5 pumps to purge each caliper of air and that is all there is to bleeding your brakes.
