1975 Honda CB750K · Brake Caliper Rebuild Kits, Caliper Pistons, Bleed Screws Buying guide

Choose the seal-and-hardware kit or an individual caliper part

The rebuild kit groups the sealing ring, bolts, bleed hardware and adjuster pieces. The piston is a separate purchase. Compare the dismantled caliper with those contents before ordering both a kit and individual repair parts.

Check the piston before deciding the kit is enough

The replacement piston is specified at 38.15 mm diameter and 34 mm length, reference 45107-300-003. Compare it with the actual caliper and removed piston. The kit’s seal and hardware do not establish that the caliper body or piston can be reused.

Choose the adjuster package for an isolated hardware repair

The individual adjuster set contains the bolt, spring, washer and nut. Those same types of adjuster pieces also appear in the larger caliper-kit contents. Check the pieces needing replacement before purchasing both packages.

Common questions

Does the rebuild kit include a piston?

No piston is named in its contents. It supplies the sealing ring, two caliper bolts, bleed screw and cap, plus the adjuster components. The piston has a separate listing.

Can I buy a replacement sealing ring without the hardware kit?

Yes. The individual ring replaces reference 45108-300-003. Match it to the fitted caliper before choosing it for a seal-only repair.

Can I replace only a missing bleed-screw cap?

Yes. The separate stock-type rubber cap replaces 45110-300-003. Compare that product with the fitted bleed screw rather than ordering a metal screw when only the cap is missing.
