1973 Honda CB450K Pad Pairs, Hose Routing & Rear Brake Service

It gives a two-piece package and size groups 52 × 20mm and 52 × 12.8mm, with multiple Honda references. Compare both removed pads and their actual shape. Confirm any missing locating or dimensional detail needed by the changed caliper before using only the size groups.

The hose A listing describes the 13.75-inch joint-to-pipe hose but does not confirm a guide is included. The separate guide replaces Honda 45129-300-000. Inspect the retained guide and hose route, then confirm supplied contents before adding another guide to the order.

Match the retained springs and their attachment points against reference 43151-346-000. The set supplies two springs but gives no complete dimensional drawing. Confirm any missing measurements needed by changed shoe attachments instead of assuming the motorcycle application establishes every replacement-shoe connection.
