1977 Honda CB750K — Trousses de réfection, pistons et vis de purge d’étrier

The piston sealing ring is sold separately as reference 45215-533-004. The larger kit adds caliper bolts and washers, bleed screw and cap, plus the adjuster set. Choose the package after identifying which retained pieces need replacement.

The kit separately lists the 1977–78 CB750K without that serial restriction. The CB750F-2000003 to CB750F-2022317 range is attached to the 1976 F application. Use the line for the actual model, and identify any substituted caliper before choosing the kit.

Its contents already include pads, piston, piston seal, both body halves, bleed screw, cap and bolts. Compare those against individual items in your order. The complete assembly does not itemize the adjuster set that appears in the rebuild-kit description, so confirm any needed adjuster hardware separately.
