1973 Honda CB500K Brake Friction & Line Positions

The 15-inch Hose B references 45126-300-003 and connects the master cylinder to the three-way joint. The separate 13.75-inch Hose A references 45125-300-003 for the joint-to-pipe position. Match both endpoints and the current routing before choosing the replacement.

Both pad shapes must match the compatible caliper: 52 x 20 mm and 52 x 12.8 mm, including their locating features. The package supplies two pads for one front caliper. The rear two-shoe set has the separate 43120-283-670 reference.

The rigid pipe is separately listed under 45128-323-020 at approximately eight inches overall. Other hoses, junctions, banjo bolts and sealing washers are excluded from a single hose order. Compare the fitted pipe reference and connections when assembling the line-service order.
