1975 Honda CB550F · Front master cylinder parts Buying guide

Identify the master cylinder before choosing its parts

Rebuild kits, reservoir caps and replacement assemblies are not interchangeable by appearance alone. Match the existing cylinder and connections; distinguish a cap supplied with a diaphragm from a cap supplied with a plastic O-ring.

Choose an internal repair or a complete assembly

The rebuild kit replaces reference 45530-377-305 and is listed for this model year. Inspect the original bore and body before rebuilding. A replacement assembly offers a different purchasing choice: compare its stated piston size, hose outlet, lever layout and brake-light arrangement with the actual front brake before selecting it.

Check the reservoir and hose-junction seals

The featured round reservoir cap includes a diaphragm. If the existing cap is reusable, the linked separate diaphragm replaces reference 45520-300-000. The other linked item is the rubber boot at the brake hose and master cylinder junction. Inspect these separate locations before choosing the seals needed for your repair.

Front Master Cylinder Parts FAQs

Will the rebuild kit fit an aftermarket master cylinder?

The kit is listed for the original-style 1975–76 CB550F application and reference 45530-377-305. An aftermarket cylinder can use different internal parts. Identify its manufacturer, model and bore, then confirm the correct rebuild kit for that specific assembly.

Is the 14 mm assembly the same as the 5/8-inch option?

No. Those are different stated piston sizes. Choose according to the installed brake system and the assembly specifications, rather than treating similar black bodies and silver levers as proof of equivalent hydraulic operation.

Which cap includes the reservoir diaphragm?

The featured round thread-on cap includes a diaphragm, replacing cap reference 43513-MJ6-006 and diaphragm reference 45520-300-000. The other reproduction cap with reference 45513-341-771 is supplied with a plastic O-ring. Compare the contents before ordering.
