1977 Honda CB550K — Plaquettes, mâchoires, durites et tiges de frein

The description gives two different dimension pairs, 52 × 20 mm and 52 × 12.8 mm. Compare both fitted pad positions with that information before ordering the set, especially where the motorcycle’s caliper has been changed.

The pipe description gives approximately 8 inches total length and reference 45128-323-020. Compare its shape, connection arrangement and the removed pipe with the listing; the approximate length alone is not a complete mounting comparison.

Yes. The separately listed spring set contains two springs and references 43151-346-000. Compare the fitted rear-brake parts and the repair requirements before adding it; the rear-shoe listing itself names a two-shoe package.
