1983 Honda CB550SC · Brake & Clutch Hydraulics Buying guide

Choose the kit for the correct cylinder

The front brake master and clutch master kits have different references. The slave kit lists seals, spring and a cap, while its piston is separate. Keep reservoir and pushrod components tied to their stated roles.

Keep the pushrod kit separate from the master kit

The clutch pushrod kit contains a pushrod referencing OEM 22884-MB0-006 and a bushing referencing 22885-MB0-006. The clutch master rebuild kit has a separate reference and does not itemize its contents. Check both descriptions rather than assuming these parts are duplicated or bundled.

Compare reservoir and slave parts by function

The front reservoir diaphragm references 45520-MA5-671 and two other numbers. The clutch slave piston references 22863-MB0-003. These components serve different assemblies; compare the removed part and its function before using a broad cylinder-category name to choose a replacement.

Brake & Clutch Hydraulics questions

Does the slave kit supply the separate piston?

The slave kit lists an oil seal, spring, piston cup and bleeder-bolt cap. It does not name the separate piston referencing 22863-MB0-003 as supplied, so confirm what the repair needs before combining orders.

Are the front and clutch master kits interchangeable?

They have different stated functions and references: 45530-MA4-671 for the front brake master and 22886-MB0-305 for the clutch master. Both list the CB550SC, but that shared application does not establish interchangeability.

Is a universal master cylinder automatically an original-size replacement?

No original CB550SC bore size is established by the universal-unit descriptions. Their 13mm single-disc application is a condition to compare with the fitted brake, alongside mounting, fittings, switch and mirror requirements.
