Reproduction Honda bleeder valve for the front brake caliper. This valve is usually stuck in the caliper due to rust or from someone using gorilla like force to tighten it. Once you do get the darn thing off, the 10mm hex is most likely stripped or marred by the vice grips you used. We won't tell...just replace it and brake with confidence. We also have the Genuine Honda rubber cap that goes on top of the valve as well as a replica caliper.
Note: Check the fitment list below, this does not fit all years of the CB450K and CB750K. It fits the finned front brake caliper. This reproduction is chromed steel but the original bleeder was black.
