1986 Honda CB450SC Nighthawk · Brake & Clutch Buying guide

Let each component reference determine its own repair order

The front pad set serves one compatible caliper and measures approximately 90 × 49 × 9 mm per pad. Rear shoes arrive as a matched pair at 139 × 40 mm. The front-master kit names 45530-MA4-671; clutch friction and spring purchases have their own stated supply formats.

Identify caliper pieces before counting a hydraulic rebuild

The piston listings identify two different diameters for the CB450SC front application. Measure the removed part and confirm its Honda reference and caliper identity before choosing. Their shared motorcycle application does not make the 30.15 mm and 27 mm pistons interchangeable or establish that both should be bought together.

Keep clutch service findings separate from brake repair quantities

The clutch spring package contains four springs, while main friction plates are sold individually with six specified. Measure spring free length and inspect plates, basket fingers and hub to decide the work needed. A complete spring package does not settle which plate groups the retained clutch requires.

Parts ordering FAQs

What details identify the front pad order for this model?

Use Honda reference 45105-KN8-026 and compare the removed pads with the approximately 90 × 49 × 9 mm dimensions. Each Kevlar set services one compatible front caliper. Count the matched calipers being serviced without transferring another Honda model’s installed quantity.

How should the rear shoe order be counted alongside the clutch plate order?

Rear shoes are supplied together as two matched 139 × 40 mm pieces for one compatible drum. Main 22201-333-010 / 22201-ML4-610 clutch friction plates are individual items, with six specified. Apply each listing’s supply format when calculating the packages for the planned service.

What could add caliper hard parts to a seal-kit repair plan?

Inspect the piston and bore for corrosion, scoring or plating damage, as the deluxe-kit listing advises. New seals cannot correct damaged hard parts. Confirm the required piston’s dimensions and reference, then choose any necessary hard-part repair separately from one-caliper kit coverage.
