1982 Honda CB750F · Master Cylinder Parts Buying guide

Front kit, rear kit or reservoir parts?

The 1982 CB750F listings separate front and rear master-cylinder rebuilds from reservoir repairs. The selected front reservoir kit and chrome cover are two-screw types, while the round cap is listed for the rear master cylinder.

Identify the separate front cover and diaphragm

For a separate front diaphragm, 08-0284 lists Honda 45520-MA5-671 and 45520-MA5-672. The chrome cover 29-0071 lists 45513-MA5-671 and 45513-413-941. These are individual product choices alongside the reservoir package, so distinguish the cover reference from the diaphragm reference.

Keep internal-kit scope tied to the cylinder

The front and rear rebuild kits have separate F-model applications. The rear kit listing specifies one compatible master cylinder per kit. The reservoir package and separate reservoir parts are different purchases from either internal rebuild kit.

Master-cylinder buying questions

Is the 1982 CB750K front kit the same as the F-model kit?

No. Kit 08-0201 is listed for the 1982 CB750K with reference 45530-MA4-671. This F-model page uses 08-0209 with 45530-MA5-671. The supplier lists separate K-model and F-model applications, so the shared year and CB750 name do not identify the same kit.

Does the round rear cap come with its diaphragm?

Yes. Part 29-0080 includes one round thread-on cap and one diaphragm. The cap replaces 43513-MJ6-006 and the diaphragm replaces 45520-300-000.
