1973 Honda CB350G Front Caliper Parts

The CB350G front disc can be serviced with separate piston, sealing-ring and hardware choices, or an aftermarket caliper assembly. Inspect the original body before deciding between these approaches. A replacement assembly may still require final assembly, installation and bleeding before use.

1973 Honda CB350G · Front Caliper Parts Buying guide

Decide whether to repair or replace the caliper

Choose individual parts for a serviceable caliper body, or assess the replacement assembly when the original is damaged or missing. Confirm the actual fitted caliper before relying on the model application.

Separate piston and seal purchases

The piston and sealing ring are separate products. A new piston alone does not provide every part needed for a caliper repair. Inspect the bleed screw, body and retained hardware, and select replacements that correspond to the diagnosed damage.

Know the assembly contents

The aftermarket assembly includes its body, pads, piston, piston rubber, bleed screw, bolts and bleed cap. It is sold each and may need final assembly. Treat it as a brake-service job requiring correct inspection and installation, not a ready-to-ride guarantee.

Buying questions

Is the sealing ring included with the separate piston?

The piston and sealing ring are offered separately here. Build the repair order from the parts being replaced rather than assuming the piston is a complete rebuild kit.

When should I consider a full caliper assembly?

Consider it when inspection finds the original body unsuitable or the caliper is missing. Verify the fitted brake arrangement and the replacement assembly’s application before buying.

Are caliper mounting bolts available separately?

Yes. The related bolt-and-washer set contains two bolts and two washers. It is distinct from the separate bleed screw and the piston-and-seal choices.

Not sure which part you need?

Send your model and year, plus photos of your existing part and any changes to the original setup.
