Frequently Asked Questions

How many front-caliper bleed screws are included?

One bleed screw replacing Honda OEM 45109-300-003 is included, enough for one compatible front caliper on a 1969-1976 CB750K or 1970-1971 CB450K.

Is the rubber bleed-screw cap included?

The matching stock-type rubber cap is a separate part. One cap is used over each installed bleed screw to keep contamination out.

What should be checked if a new bleed screw still leaks?

Inspect the screw's sealing cone and the caliper seat for corrosion or damage, then bleed the brake and hold firm pressure while checking for leakage. Do not rely on thread sealant to repair a damaged hydraulic seat.
