1982 Honda CB900C Custom · Caliper Rebuild Parts Buying guide

Rear-piston fitment warning

For the original rear caliper described in Honda’s 1982 CB900C specification table, the listed 30.15 mm piston does not match the specified diameter. Do not order 29-0509 as a rear replacement from this guide.

Honda specifies different front and rear piston diameters

Honda’s March 1982 CB900C table on page 26-8 gives front piston outside diameter as 30.148–30.198 mm and rear piston outside diameter as 26.918–26.968 mm. It does not support using the listed 30.15 mm piston at both ends.

Select kit coverage before adding parts

The front dual kit is explicitly described as repairing two calipers; the rear kit repairs one. Inspect piston condition separately rather than assuming either kit renews the pistons. Follow the service manual when deciding whether a caliper body remains suitable for rebuilding.

Caliper Rebuild Parts questions

Does this piston fit both ends of the 1982 Custom?

No. Its listed 30.15 mm diameter conflicts with Honda’s rear specification. The catalog’s rear-fitment claim needs correction or verified clarification before this piston is selected for the original rear caliper.

Does matching the front diameter verify the complete replacement piston?

No. Honda’s table gives outside diameters; it does not verify this replacement piston’s 35 mm length or complete part identity. This guide has not established an alternative rear piston.

Is one rear kit enough to service both front calipers?

No. The rear kit is a one-caliper repair kit for the rear application. The separately featured front dual kit is the one specified to repair both front calipers.
