1974 Honda CB750K · Master Cylinders & Rebuild Parts Buying guide

Choose master cylinder parts for the assembly you have

Rebuilding an existing cylinder and replacing the complete unit require different checks. Identify the cylinder first, then compare internal kit references, reservoir shape and any electrical or hose connections involved.

An assembly and a rebuild kit are different choices

A rebuild kit must suit the existing cylinder; a complete replacement can have a different piston size, lever or switch arrangement. Compare those details with the braking system on your motorcycle. Have the original cylinder assessed before deciding whether rebuilding or replacing it is appropriate.

Include the reservoir and external rubber parts

The linked reservoir cap replaces 45513-341-771 and includes a plastic O-ring. The separate diaphragm replaces 45520-300-000. Check the chosen cap’s contents before adding seals or assuming every cap package is supplied alike.

Common questions

Will a stock rebuild kit fit a replacement master cylinder?

It depends on that cylinder’s internal dimensions and design. A replacement unit can look similar while using different components. Identify its manufacturer or reference and compare the kit specification before ordering internal parts.

Does a larger piston size automatically improve braking?

Piston size affects how a master cylinder works with the rest of the system. It should be selected for that system, not treated as a universal upgrade. Seek an informed compatibility assessment for a changed brake setup.

Which sealing parts are included with the reservoir cap?

The 29-0054 cap includes its plastic O-ring. A different cap listing, 29-0080, includes a diaphragm. Select the cap for the fitted reservoir and compare the included sealing parts before ordering extras.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
