1970 Honda CB450K · Brake & Clutch Buying guide

Build a separate parts list for each assembly

Brake pads name dimensions and locating features, while the complete aftermarket caliper lists its supplied components. Hand-control parts and brake-rod hardware remain separate repairs. Clutch plate descriptions give per-bike counts that must be distinguished from the quantity supplied by a purchase.

Parts to consider

1969-76 Honda CB750K / CB450K Front Friction Pad Set ~ Replaces 45105-341-305 Front pads with distinct locating featuresKevlar pad set referencing Honda 45105-341-305 / 45106-341-000B. Listed dimensions are 50 × 54 × 20mm and 50 × 26.7 × 12.7mm, with one locating pin and one locating tab. Compare the fitted caliper’s pads.View part Honda CB Clutch Friction Plate ~ Replaces 22201-MA7-000 Friction clutch replacement platePlate referencing Honda 22201-MA7-000 / 22201-283-000. The CB450K application states seven pieces per bike. Confirm the quantity supplied by the purchase before calculating how many plates to order.View part Honda CB750/CB700/CB650/CB550 Brake Rod Joint Separate brake rod / arm jointJoint referencing Honda 95015-32001. Match the rod-to-arm connection currently fitted. The joint pin and adjusting nut have their own listings and should be assessed as separate linkage components.View part

Choose caliper repair scope before adding pads

The complete aftermarket caliper lists pads, piston, seal and bleed hardware among its contents. Separate parts offer a different scope when retaining the existing caliper. Read the chosen package before adding the same components again, and compare the brake arrangement on the motorcycle rather than assuming every assembly has remained original.

Keep custom masters and clutch quantities explicit

The universal Honda-type master has a 13mm bore and single-disc specification, but still needs a suitability check for the custom hydraulic setup. For the clutch, seven friction and six steel pieces are stated per CB450K; confirm how many pieces each purchase supplies before turning those figures into an order.

Practical parts selection questions

Does the complete caliper remove the need to check the rest of the brake order?

It expressly includes pads, piston, seal/ring, piston cap, bleed screw and cap, bolts and clip with both body halves. Check those contents to avoid duplicate purchases, then inspect the other retained brake components. The caliper listing does not describe a complete brake system.

Can the same pivot set be assumed for brake and clutch levers?

The brake set references 90114-300-000, while the clutch set references 90114-310-000 with nut 94001-06200-0S. Each supplies one bolt and nut. Compare the appropriate side and its retained control instead of assuming their references establish interchange.

What dimensions does the rotor listing give for a changed front end?

It supplies Honda references 45120-392-000 / 45120-300-040 / 45120-341-000, but no complete diameter, thickness or mounting drawing. Compare the retained rotor and mounting, and confirm missing dimensions before choosing it for altered components.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
