1982 Honda CB750K · Master Cylinder Parts Buying guide

Keep the original-type repair and replacement assembly distinct

Master kit 08-0201 lists the 1981–82 CB750K and replaces reference 45530-MA4-671. Reservoir kit 29-0051 supplies a different group of parts. Complete assembly 08-0457 is an aftermarket alternative described as similar to, but not identical to, the original.

Parts to consider

Check the package against the repair

Reservoir kit 29-0051 lists a plastic reservoir, cap, diaphragm, O-ring and screw for the two-screw cover type. Master kit 08-0201 gives its application and replacement reference without an itemized contents list. Confirm any specific internal part you need before assuming it comes with that kit.

Record an aftermarket master cylinder’s identity

If assembly 08-0457 is fitted, keep that part number with the motorcycle’s service records. Its replacement-lever listing is expressly for 08-0457 and excludes stock master cylinders. Similar appearance does not establish that the original lever or internal repair kit fits the replacement assembly.

Common questions

What brake-light connection does assembly 08-0457 use?

Its integrated brake-light switch has two small spade connectors. Compare those connections with the wiring on your motorcycle before buying the assembly; the listing does not describe a complete replacement wiring harness.

Does the replacement cylinder include a lever, or must I buy one?

Assembly 08-0457 is described with a black lever. The separately listed replacement lever is for servicing that specific assembly, and its description says it is not for stock master cylinders. Identify the cylinder before ordering a spare lever.

Will the 1981–82 stock-application rebuild kit service assembly 08-0457?

The current descriptions do not establish that compatibility. Kit 08-0201 lists the motorcycle application and reference 45530-MA4-671; assembly 08-0457 is expressly non-identical to the original. Ask for repair parts matched to the actual assembly instead of carrying over the model-year kit.
