1972 Honda CB450K — Maîtres-cylindres et pièces de réfection

Identify the master cylinder fitted to your 1972 CB450K before selecting an internal kit or reservoir component. A universal replacement needs another set of hydraulic and attachment checks. Compare the repair scope, cap contents and included fittings before committing those different choices to one order.

1972 Honda CB450K · Master Cylinder & Rebuild Parts Buying guide

Match service parts to the master that stays on the bike

The rebuild kit references 45530-377-305 without an internal piece list. Reservoir options include a round cap with diaphragm, a cap with plastic O-ring and a separate diaphragm. Universal Honda-type and Magura masters document different fittings, dimensions and mirror provisions.

Parts to consider

Identify the master retained on the bike and confirm essential contents, because no detailed internal component list is given.Voir la pièce Honda CB Master Cylinder Reservoir Cap ~ Replaces 43513-MJ6-006 Round reservoir cap including diaphragmThread-on cap referencing Honda 43513-MJ6-006, supplied with diaphragm 45520-300-000.

Distinguish the reservoir’s separately described sealing parts

Cap 43513-MJ6-006 includes diaphragm 45520-300-000. Cap 45513-341-771 lists a plastic O-ring without itemizing a diaphragm, and a separate plastic O-ring product references 45521-MJ6-006. Compare the retained cap and repair need before combining these choices; their different contents are not interchangeable package descriptions.

Review the complete custom installation before choosing a master

The Honda-type unit has a 13mm bore, included lever, banjo hardware and switch, plus right-hand mirror thread. Magura states 13mm piston, 12mm stroke, separate switch and banjo hardware, and no mirror mount. Confirm the actual system and missing attachment specifications; neither universal unit inherits the model-listed rebuild kit’s fitment.

Master repair scope and custom fitting questions

How can I confirm a specific internal component is in the rebuild kit?

The listing gives reference 45530-377-305 but does not itemize the kit. Identify the retained master and confirm the required internal piece before ordering. A kit photograph or motorcycle application cannot establish compatibility with an unspecified universal replacement.

Which cap purchase already covers a diaphragm repair?

The round thread-on cap expressly includes diaphragm 45520-300-000. The other cap lists a plastic O-ring without itemizing a diaphragm. Match the retained reservoir and compare these contents before adding a separate diaphragm for the same service location.

What else should I check when a mirror is needed with a universal master?

The Honda-type unit states a right-hand-threaded mirror mount without complete thread dimensions. Magura states no mirror mount and identifies that hardware separately. Compare the actual mirror attachment and any missing dimensions alongside hydraulic, switch and brake-line compatibility.
