1982 Honda CB450SC Nighthawk · Master Cylinder & Rebuild Parts Buying guide

Choose by fitted assembly and the parts it needs

The internal kit identifies Honda 45530-MA4-671. The reservoir kit supplies a plastic reservoir, cap, diaphragm, O-ring and screw for the two-screw cover type. The universal Honda-type assembly has a 13 mm bore for single-disc systems and a stated bundle of control and connection parts.

Keep reservoir and internal service requirements distinct

Inspect which component actually needs renewal before combining the two kits. The reservoir package itemizes its sealing and cover components. The internal kit gives a Honda application reference but does not itemize every supplied piece, so confirm its contents rather than assuming it includes reservoir hardware.

Allow for the different universal assembly bundles

Both universal choices are described for single-disc systems. The Honda-type listing includes connection hardware and a brake-light switch. The Magura listing instead sells those connection items separately, specifies a 12 mm stroke, and has no mirror mount. Check hydraulic suitability before treating either as a replacement.

Common questions

Which parts are supplied with the two-screw reservoir kit?

The package lists a plastic reservoir, reservoir cap, diaphragm, O-ring and screw. It is for the two-screw cover type. Compare the fitted reservoir style before ordering, and assess internal master-cylinder service requirements separately from this itemized reservoir package.

What extra items should I budget for with the Magura assembly?

The Magura listing sells the brake-light switch, M10 x 1.0 banjo bolt and sealing washer separately. It also has no mirror mount. Include a suitable mount when needed, and verify the connections before building a custom assembly order.

Can I choose either universal 13 mm assembly by the motorcycle name alone?

Both listings describe universal assemblies intended or recommended for single-disc systems. The Magura FAQ explicitly requires the bore to match the brake system’s hydraulic requirements. Verify the installed system, connections and mounting arrangement rather than relying on the motorcycle name.
