1984 Honda CB450SC Nighthawk · Front Pads & Rear Shoes Buying guide
Both front sets include the 1982–85 CB450SC application and share 45105-MA5-771 among their references. Their other reference numbers differ. Rear shoes identify 43120-413-006 and a 139 mm diameter by 40 mm width; two shoes form the supplied matched set.

The Kevlar listing also includes particular 1982 CB750 frame-number limits. Its separate CB450SC entry covers 1982–85 and carries no equivalent cutoff. Confirm the CB450SC pad application from its own reference and shape rather than borrowing restrictions from the larger motorcycle.
The shoe FAQ calls for checking the drum surface and service-limit diameter, return springs, cam and pivots. Those retained components are not itemized as shoe-package contents. Assess their condition before assuming the matched pair represents every part the rear brake will require.
No CB450SC cutoff is stated. The Kevlar listing names its CB750 frame limits separately and lists 1982–85 CB450SC front brakes. For this application, compare the pad shape and the stated Honda references rather than applying the CB750 serial restriction.
One package already contains the two matched shoes used in one compatible rear drum. Each shoe is specified at 139 mm diameter by 40 mm wide. Compare that sizing and 43120-413-006 before counting a second set for a different repair.
Check the drum surface, service-limit diameter, return springs, brake cam and pivots, as the shoe listing recommends. The supplied pair renews the friction shoes. Findings at those retained components can identify additional service needs before the order is finalized.
