1974 Honda CB750K · Caliper Rebuild Parts Buying guide

Plan a caliper parts order without missing small pieces

A piston, its sealing ring and the caliper hardware are separate purchasing decisions. Start with an assessment of the fitted assembly, then choose a kit or individual components that cover the required parts.

Compare the kit with individual parts

The featured rebuild kit lists a sealing ring, two caliper bolts, bleed screw and cap, plus an adjuster set. Its contents do not list a piston. If assessment identifies a piston replacement as necessary, compare that separate listing with the fitted caliper before completing the order.

Check the assembly before choosing a repair

Corrosion, damaged threads or previous modifications can affect whether individual replacement components are suitable. A seal kit cannot establish the condition of the caliper body. Have the assembly assessed, and use the correct service information for any hydraulic brake work rather than treating a kit as a diagnosis.

Common questions

Is the piston included in the featured caliper kit?

The kit lists the sealing ring, two bolts, bleed screw, cap and adjuster set. A piston is not listed in those contents. The featured replacement piston is a separate product for comparison when needed.

Do I need a separate adjuster set when buying the caliper kit?

The kit already includes the adjusting bolt, spring, washer and nut. Those four pieces are also sold as an adjuster set, so check the kit contents before adding a duplicate.

Can these parts be used with an aftermarket caliper?

An aftermarket caliper may use different piston dimensions, seals, threads and hardware. Match its own specifications rather than the motorcycle year alone. These listings should be compared with the actual caliper that will receive the parts.
