1971 Honda CB500K · Pads, Shoes & Brake Lines Buying guide
Front pad and rear shoe sets address different brakes. The hydraulic listings distinguish the master-cylinder hose from the lower hose and rigid pipe, so check the complete routing before selecting a single replacement section.

Hose A is listed between the three-way joint and front brake pipe. Hose B runs from the master cylinder to the three-way joint and measures 15 inches. These are individual sections, so ordering either one does not provide both hoses or the metal pipe.
Before ordering friction parts, inspect the disc or drum and the associated hardware. For line work, compare the fittings and existing junctions as well as length. A changed handlebar or aftermarket master cylinder may alter routing even when the motorcycle retains its original model identity.
Hose B is the 15-inch master-to-three-way-joint section, referenced to 45126-300-003. Hose A measures 13.75 inches and runs from that joint to the front pipe. Compare endpoints and routed length when handlebars or brake plumbing have changed.
The separate rigid pipe references Honda 45128-323-020 and measures approximately eight inches overall. Match the reference and fitted connections rather than length alone. The hose listings exclude other line sections, junctions, banjo bolts and sealing washers.
Compare both supplied pad shapes, 52 x 20 mm and 52 x 12.8 mm, with the caliper’s locating features. One package supplies the two pads for one compatible front caliper; the rear shoe package separately references 43120-283-670.
