1973 Honda CB350F0 · Front Brake Caliper Parts Buying guide

Rebuild a sound caliper or replace a damaged assembly

The separate piston and seal support a targeted repair. The aftermarket caliper includes its main components but can need final assembly, so treat its contents as the start of a properly checked brake service.

A piston and seal are separate choices

The replacement piston is 38.15 mm in diameter and 34 mm high. The sealing ring is a separate product, so include it when the repair requires both. Inspect the bore, seal groove and other caliper parts under the service procedure rather than assuming a piston alone completes the job.

Check the replacement assembly before fitting

The aftermarket caliper includes the body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. Final assembly may be required. Have the assembly checked, installed and bled correctly before the motorcycle returns to use; the package is not a substitute for a complete brake-system inspection.

Common questions

Does the piston come with its sealing ring?

The piston and sealing ring are separate products here. Order the ring separately when rebuilding with a new piston, and inspect the other caliper components before completing the parts list.

What comes with the replacement caliper?

It includes the body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. The assembly may require final assembly and still needs correct installation and bleeding.

When is a complete caliper the better purchase?

A missing or damaged caliper body may make a replacement assembly more suitable than individual internals. A competent inspection of the body and sealing surfaces should decide whether the original can be rebuilt safely.
