1982 Honda CB750C · Master Cylinder Repair Buying guide

Separate reservoir repair from internal hydraulic work

The reservoir kit includes its plastic body, cap, diaphragm, O-ring and screw. The internal kit replaces 45530-MA5-671. A complete aftermarket assembly has its own lever and electrical-connection requirements.

Match the repair kit to the retained body

The original-application internal kit replaces 45530-MA5-671 for the 1981–82 CB750C. Compare that reference with the actual master cylinder. Reservoir sealing pieces are supplied in a separate package, so choose the scope that addresses the inspected condition.

Review a replacement as a complete control

The aftermarket unit has a 15.8mm piston, black lever and integrated brake-light switch with two small spade connectors. Compare the retained hose connection and electrical terminals. Its dedicated replacement lever is different from the lever intended for the stock master cylinder.

Master Cylinder Repair questions

What identifies the reservoir package?

It is the two-screw cover type and includes the reservoir, cap, diaphragm, O-ring and screw. Compare the existing reservoir shape and fixing arrangement before selecting it.

Does the original internal kit service an aftermarket master cylinder?

Use the parts specified for the actual replacement body. The original-model rebuild-kit application should not be extended to another master cylinder merely because it is installed on a CB750C.

Which brake-light connection does the replacement use?

Two small spade terminals at its integrated switch. Compare the retained wiring and make a complete connection plan before choosing the replacement assembly for the front brake.

Not sure which part you need?
