These brakes are original vintage parts Made in Japan. Complete brakeset in good condition. A sicker is missing and the rubber on the pads is old, one is cracking (but it seems fine to me and I doubt it even needs to be replaced right away). Nothing I'd missing. Bolts, washers, internal bushings, dust covers, springs, tensioner washers, straddle cables, straddle harnesses, levers, cantilever arms. It's all there in good condition.
