1983 Honda CB450SC Nighthawk · Front Caliper Bleeder Buying guide

Select the bleeder using its caliper application

Each order supplies one screw for one compatible caliper. Its FAQ emphasizes exact thread and seat design, not a visual approximation. The detailed fitment names the 1983 CB450SC; frame-number conditions elsewhere in the listing belong to the other Honda applications specified there.

Treat replacement calipers as their own hardware application

A changed caliper must be identified before its bleeder is selected. Use the casting and required Honda reference to confirm the thread and seat. The Nighthawk application cannot establish which screw belongs in an unidentified caliper installed during earlier repairs.

Look at both sides of the sealing joint

The screw seals against the caliper’s conical seat, which the listing instructs you to inspect. Keep that retained surface in the repair assessment. The selection here supplies only the bleeder, so a damaged caliper seat or additional internal service requirement needs a separate plan.

Common questions

Do the other Honda frame-number notes apply to my 1983 CB450SC?

The detailed fitment gives those frame-number conditions for specific CB750 and CB650 applications. Its 1983 CB450SC line has no such cutoff. Match the actual caliper and 45224-413-003 reference without transferring another model’s frame condition to this motorcycle.

Is the package quantity based on the number of front calipers?

The package contains one screw. Count the compatible calipers whose bleeders you are replacing and verify that each uses 45224-413-003. The FAQ’s two-screw note is conditional on two fitted calipers requiring the same reference, rather than a Nighthawk-wide count.

Should I inspect the caliper seat before buying for a leaking bleeder?

Yes. The product FAQ calls for inspection of the conical sealing seat inside the caliper. Confirm the screw application and the condition of that retained seat before choosing the repair; the package does not renew a damaged caliper sealing surface.
