1973 Honda CB750K · Master Cylinder & Rebuild Parts Buying guide

Match the rebuild parts to the actual master cylinder

A complete replacement assembly, internal rebuild kit and reservoir diaphragm are separate choices. Start with the fitted unit identification, then compare the listing references and the exact rubber or hardware piece needed.

Separate internal rebuilding from reservoir service

The reservoir diaphragm is reference 45520-300-000; the hose-junction boot is a different location. The 1973–74-specific boot and reference 45522-300-010 are separate choices. Compare the fitted unit and rubber shape rather than assuming identical parts from overlapping model applications.

Replacement assemblies need their own checks

The offered replacement assemblies include a 14 mm piston option and a 5/8-inch piston option. These are specifications of the replacement units, not proof of your original bore. Identify the installed assembly before choosing its rebuild kit or replacement lever.

Common questions

Will the featured rebuild kit fit every replacement master cylinder?

The kit is specified under reference 45530-377-305. That application does not establish fit for every later replacement cylinder. Identify the fitted assembly and its required service parts before ordering.

Do the two stock-look replacement cylinders have the same piston size?

The silver-lever replacements include separate 14 mm and 5/8-inch piston options. Match the required assembly and brake arrangement rather than treating a similar external appearance as proof of the same internal parts.

Does the replacement reservoir cap supply its plastic O-ring?

The reproduction cap referencing 45513-341-771 includes a plastic O-ring. It is expressly paired with the offered silver-lever replacement master cylinders. Check the cap and retained reservoir before adding a separate O-ring.
